last ditch goose

the local patch list has clearly fizzled out as it often does in December so I took the opportunity to add one bird to the Scunny year list with a European White-front accompanying a small group of 140 Pink-feet; a much larger flock of 1650 Pinks just  mile away held nothing different; so 208 for the year on the Scunny list and it looks like the patch list will stick on 180 unless something dramatic happens in the next week which seems unlikely

bat and gull






a decent afternoon on the patch; the two Twite still around although not very approachable, plus Grey Wag, Marsh Harrier, drake Smew, Long-tailed Duck and a large bat presumably a Noctule being mobbed by a Black-headed Gull; while trying to get some photos of the bat a first-winter Glaucous Gull flew through albeit in terrible light -- it takes the patch year list to 180 equalling the third highest ever total obtained in 2002;

one more

waiting for the possible return of the White-rumped Sand at Alkborough I received a call from JH to the effect that there were two Twite on the bank at Chowder where I had spent 5 hours on Saturday with the Snow Buntings; I managed to get back in time to see them before the clouds merged into total blackness and the rain and hail reduced visibility to a few yards. 179 on the patch  list and 207 for the Scunny area; and the most ridiculous missing bird on the patch list Green Sandpiper - but then again there has only been one record this year and that was 9 days ago!

White-rumped Sand

doing a routine survey at Alkborough this afternoon I was amazed to come across a White-rumped Sandpiper with a small flock of Dunlin feeding on the snow and ice covered mudflats; the latest ever in Lincolnshire it showed well for about 40 minutes before disappearing into the fading light in the middle of the site; it takes the Scunny year tally to 206

205 scunny area

finding a Green-winged Teal this am was a bonus but not a year tick -- a Slavonian Grebe though was and it was followed by a Tundra Bean Goose with the Read's Island Pinks making the scunny area total 205 for the year

manflu gulls

with a particularly bad case of manflu I certainly did not feel like getting out of bed this morning but the northerly wind had been howling all night accompanied by heavy rain which must have produced something on the Humber? so at 07:30 I was in position and by 08:00 was certainly wishing I had stayed in bed with nothing to put in the notebook in spite of the conditions; Two Common Scoter tried to liven things up but it was still dire until a juvenile Kittiwake took the patch list to 177; an expected addition it was not accompanied by any auks, grebes or divers but a Bonxie then moved up and back out along with a passage of big gulls mainly GBB's -- and as can happen a totally unexpected bird appeared in front of us and duly landed on the Humber for about 30 minutes before flying around for another 15 minutes - a third winter Iceland Gull was most unusual on this date and a rare addition on the patch year lists so this one was most welcome --a flock of 27 Common Scoter a drake Goosander and another Bonxie added to the day tally before the flu forced an early retirement leaving the patch year list on 178 still a long way from the record 184 in 1996 but there must still be a chance of an arctic blow with a wad of auks and divers, Slav and Red-necked Grebes and some wild geese, Bewick's Swans or even a Spotted Redshank

Bombycilla

I abandoned a trip to the coast to have a look through the thrushes on the patch this morning; in fact it took me 15 minutes to get out of the garden as I watched Blackbirds and Redwings exploding from all the adjacent gardens and gaining height before moving off westwards -- the Blackbird movement continued to midday with a few flocks of Fieldfares heading west and 2000+ Starlings in several flocks also taking the westward route up the estuary; checking the sallows for a Yellow-browed or Pallas' or even that skulking Bluetail the distinctive call of Waxwings caused me to look up and see a flock of five birds heading west with the other incoming migrants; so 176 for the patch and 203 on the scunny list -- already a scunny record could the patch list struggle on to 180 -- we need a northerly gale with some Little Auks and other seabirds!

Phal

a terrible day of local weather with heavy to torrential rain all day and a strong easterly wind during the early morning; as the rain eased for a while mid afternoon I thought Waters' Edge would be a good spot for a Pallas's Warbler but the only arrivals were a flock of 10 Song Thrushes and plenty of Blackbirds but on the mud of the rising tide walking behind a Redshank was a first-winter Grey Phalarope -- it flew onto the outflow from the local sewage plant and then made a few more flights before drifting up the estuary on the rising tide; 175 for the patch and 202 on the local scunny year list

Monday, 20 October 2008

Barnacle

I had previously ignored the noisy Barnacle Goose that accompanied the local Greylags in May but today's lone bird battling westwards into the teeth of the gale seemed a little more acceptable; it caused mass panic amongst the local waterfowl as it passed over the pits possibly due to its general resemblance to an Osprey from underneath? taking the patch tally to 174

Leach's and Merg

a twitched Leach's Petrel on the Humber off Read's Island took my Scunny tally to 200 for the year while a first-summer male Red-breasted Merganser on the Humber off Waters' Edge was a patch year tick and took the local list to 173 (still well down on the record years) and the scunny total to 201 with two and a half months still to go.

Spoons take it to 199




after not making much effort to see the adult Spoonbill at Alkborough in the spring and missing it on every visit I thought that Spoonbill had evaded my Scunny area year list so a call informing me that two immatures had just landed there this afternoon prompted a response (I had been there all yesterday afternoon so the birds were certainly new in) just prior to my arrival a helicopter flushed the birds which flew off just as I arrived! fortunately they returned about 5 minutes later and settled in to feed in the main channel taking my tally to 199 on the brink of a first ever 200; not sure if these can be tied to records anywhere else in the UK of late. Spoonbill is still the most silly species missing from my local patch list although several must fly past Barton every year-- I have even seen one from the patch but over the north bank of the estuary in Yorky land

198 Scunny Anthus richardi




tracking a couple of Lap Bunts we came across this Richard's Pipit this afternoon at Alkborough making my scunny year list 198; it was to say the least elusive

Pecs 197


finally managed to get decent views of three of the Pectoral Sandpipers at Alkborough today and firmed up the 197 on the Scunny year list which must surely now top the 200 mark

spot the Pec with Dunlin in the shot above

Brown Shrike



a new bird for Britain but a bit far to count on the local list and a bit far off even for digi-scoping!

Gannet special

after a day of north-easterlies on the 23rd with not a single Gannet today made up for the lack of that species with 108+ at the bridge this morning; a juvenile Little Stint was a second overdue addition but a juvenile Sabine's Gull was only the second patch record following  a juvenile on September 13th 1993; today's bird quickly moved out into the murk of the Humber and disappeared before providing a photo opportunity ( and I still have not had a Kittiwake!); this takes the patch year list to 172 and the Scunny list to 196 but the latter should perhaps be 197 taking into account the fly-by Pec Sands at Alkborough this afternoon -- surely they will get tied down before long but with easterlies prevalent the patch is likely to miss out for the next few days

another Scunny addition

a most unexpected close encounter with a Quail at Alkborough added a species to the scunny area year list which I had missed all summer 194;

New scunny birds





the day at Alkborough started well with a juvenile Honey Buzzard and got better with a female Redstart then it peaked when I picked up a Wilson's Phalarope; the trouble was it was 800m (measured on the map) from where I was viewing with a 27x50 scope in poor light and that tested my imagination! views from 100m confirmed the ID of this first for the Scunny recording area and a new bird for my UK self found list taking respective tallies to Scunny area total 278 Britain and Ireland self found 325 and British self-found 323; the Scunny area year list meanwhile moves on to 193
Honey Buzzard above form this morning's fly-by

Whinchat at last

after yet another search of the weedy fields of East Marsh a single Whinchat was eventually added to the local year list 169; one Opsrey was still around, a Hobby and 5 Common Terns but little else of note today

raptor roll




after the first Honey Buzzard of the morning a flock of eight Ruddy Shelduck flew west; eight must be worth a tick! then the expected Osprey turned up and stated fishing; by the end of the day there had been at least three and probably four different Ospreys through with Hobby, Peregrine, Merlin, Common Buzzard, Sparv and Kestrel; in fact it has been a raptor hot weekend as Saturday produced Marsh Harrier and 3 Buzzards on the patch and a thermal full of 3 Red Kites, 3 Marsh Harriers and 3 Buzzards at Alkborough; adding the ducks and two raptors the tally jumps to 168 for Barton and 191 for Scunny
the Ruddy flock, the juvenile Hobby hunting the dragons and one of the Ospreys

HB






high expectations of a Honey Buzzard for the list this morning saw me out on the Humber at 06:30; should have had a lie in as the first bird did not come through until 09:32; a second followed and a third (see terrible pics) was low over Far Ings mid afternoon. 166 for Barton and 189 for the Scunny area with a Whinchat on the Saturday

5 ticks in 90 minutes!

it must be a record for this late in the year and all down to a rising spring tide and a fresh east-south-easterly wind; after tea I headed down to the Humber expecting Black Tern at the very least and almost the first birds I saw were two adult Black Terns! there were a lot of birds moving with 300+ Teal and 70+ Shelduck milling around on the estuary along with 8 Common scoter and most surprisingly a flock of 11 Eiders; this species is fairly regular in late October - December but not in August; a couple of juvenile Arctic Terns were picked out amongst the passing Commons and a Guillemot put on a fine performance flying back out to seas on two occasions! finally a passing party of four Common Terns attracted the attention of an adult Arctic Skua completing the five up for the night. This takes the annual tally to 165 and the Scunny list to 187 with some silly birds still missing including amazingly Whinchat and Osprey plus that Green Sand

unexpected tick



after a morning around Far Ings NNR where the appalling lack of reserve management means that you cannot even see out of most of the hides let alone take a photo from them, I had logged six Common Buzzards together, the highest patch total ever and a few dragons -- still searching fro a Green Sand I had a scan over pursuits pit where there appeared to be a rather small sinensis Cormorant on the tern raft; it looked rather like a Shag but as I was looking into the sun I had to have a look from the other side to confirm that it was indeed a juvenile Shag, my first August patch record and a totally unexpected list addition taking me up to 160 for the patch and 183 in Scunny area; terrible digi-scoped images above; I went back in the evening when the light was better but was unable to see out of the hide!!!!! the bird though appeared to have gone as had the Black-necked Grebe but the Red-crested Pochard was still showing well

Thursday, 21 August 2008

miss one hit another

another late night and with the forecast of rain I decided on a lie in --- phone going off at 06:43 with a text -- Osprey passing over KC's --- no direction given! --so I jumped up and headed out into thick black threatening cloud but scanning all the usual spots revealed nothing --- as I was up I had a quick look at Chowder and a juvenile Ruff filled one of the obvious holes in the list; 159 up the third highest August total to date; an adult Dotterel in with a big flock of Goldies took the Scunny year list total to 182 but big fly over raptors seem to be eluding me at the moment

Wednesday, 20 August 2008

its all luck



the waders were absent at Chowder this afternoon but as I walked back to the car the sun broke through briefly so I took the camera to have a go at the late nesting Common Terns; while photographing them a caffuffle in the edge of the reeds revealed a Little Grebe in hot pursuit of a juvenile Black-necked Grebe 158! If the sun had not come out I would probably have missed this bird! the eclipse drake Red-crested Pochard was on the same pit and the two star birds were together for a while. Still missing silly birds like Ruff, Green Sand, Whinchat, Black and Arctic Terns though

another 3 tick day

well nearly a month on from the last additions and a three tick day; as the rain cleared a party of four Wood Sandpipers flew west chiffing over Chowder Ness; a female Common Scoter was on the Humber and a long overdue Greenshank put in an appearance amongst a good gathering of waders; so 157 on the patch list but the afternoon also paid dividends with fairly brief views of the Audouin's Gull at Chapel St Leonards taking my Lincs list to 341 species BOU
In recent weeks the Scunny list has reached 181 with a few notable additions including Buff-breasted Sandpiper; 

Thursday, 24 July 2008

SE + rising tide =

well usually it brings in Black Terns but tonight none appeared though I thought I heard a Sandwich Tern over Waters' Edge but only two Common terns were present; a scan of the Humber suddenly revealed a Bonxie heading west; almost annual in September - November there have been very few July records and then a Sandwich Tern called and passed right over my head! a two tick night and a three tick day so the list is looking up! 154

a new wader at last

I have not been around the patch much of late so may have missed all sorts of goodies but at least wader passage is picking up and there were 390 Dunlin on Chowder this morning accompanied by two Red (rather nice peach) Knot and a splendid orange Curlew Sandpiper an early autumn tick for this regular species normally picked up as smart juveniles in September - October. This takes the tally to 152 after a long barren spell; still not had a Greenshank yet this year and this species seems to be getting scarcer locally for some reason; others missing are Green Sand, Spotted Red and Red-necked Stint -- the latter an obvious candidate for next patch list addition!

Sunday, 6 July 2008

slow struggle

With very few gulls on the local part of the estuary it was with some good fortune that I managed to pick up a 3cy Yellow-legged Gull amongst the 10 Lesser Black-backs today; the chances of a Caspian Gull though must be minimalist with so few gulls using the patch this year; 151

rare swifts






well 8 hours and severe swift eye burn out but nothing rarer than this white Sand Martin as a reward ----
given the apparent good high ISO performance but continuing poor AF reviews on the Canon 1DIII I tried some swift shots on different ISO's with the 1DIIN -- here from the top 400, 1600, 800 and 500---- the sun helps of course

Thursday, 19 June 2008

xbill

with a lot coming in it was probably not too surprising to hear a Common Crossbill calling over Waters' edge on a beautiful evening; 2008 is however only the 4th year in the last 15 in which this rare migrant has been recorded from the patch; strangely 2007 produced three small flocks when the species was generally very scarce. 150

unexpected Jay

a late evening walk over the Wolds to listen out for Quail turned out to be rather chilly and quail free but an unexpected year tick was a Jay which flew out of Turton's covert and across the footpath onto the patch; this species is less than annual (missing years being 1997, 2000 and 2006) with autumn movements accounting for virtually all the usual records after which odd birds have wintered in the park if there has been a good acorn or beech crop; so 149 on the year list the third highest June count to date behind the record breaking 1996 and 2002 totals of 162 and 151 respectively

swift conundrums




having spend a few more hours this afternoon scanning the 300+ swifts and 100+ House Martins (new arrivals) feeding over the pits I was again struck by the conundrum that is finding a rare swift on your local patch. Over 30 years during May-August I have spent a ridiculous amount of time scanning through swifts on my local patch in the hope of picking up an Alpine or something better! in that time I have seen at least 6 birds with some white in the plumage including three with white rumps and a very striking bird (pics above) seen in two successive springs late April 2004 and May 5th 2005 (rather poor pictures above) but never an Alpine; in June 1977 I found a Pallid Swift which just failed to make it as a British first, probably a correct decision on a non-photod single observer first, and in 1998 a Little Swift which about 200 people managed to see in its one afternoon stay on the pits; the latter bird was found not while looking through swifts but hiding from a thunderstorm in a hide watching a Common Tern nest! ---I have attached the agony and trauma of the latter find below as written at the time 

Little Swift at Barton pits June 26th 1998

    

On the afternoon of June 26th I was trying to mop up any outstanding broods of wildfowl to complete the annual breeding survey of the clay pits. Dodging the regular thundery showers I found myself sitting in the hide which looks westwards over Barrow Haven reedbed at about 14-30 hrs as yet another downpour threatened to engulf the local environs. Scanning across the pit I realised that the Common Tern, sitting on its nest on a brick pillar in the next pit to the west, about 700m away, was visible from the hide; at least it would save me the trouble of walking through 700m of wet grass to check on their progress. It was at this point that I realised there were good numbers of Swifts feeding low over the Humber embankment which borders the next pit, pit25, beyond the ski pit where the terns were nesting.

With over twenty years of regular summer swift scrutiny already having passed without reward, the news of three Alpine Swift fly bys at Spurn, in recent weeks, had inspired renewed swift watching but as usual to no avail. June 26th was not intended as a swift watching day but events suddenly took a turn swift-wards as a bird with a bright white rump literally flew through my scopes field of view at over 1km range. The view was so brief I initially suspected that I had glimpsed a House Martin in strange light and had missed the white underparts. The day was thundery, with dark brooding black clouds passing quickly north-eastwards, intermixed with bright sunny spells and some glaring skyscapes. A quick scan soon revealed the bird again; it showed a bright white rump and appeared to have a contrast of blackish belly and silvery underwings but in size it was difficult to judge just how big it was at 1km range, as it did not appear strikingly different to the swifts nearby although judging which individuals were close to it was hard enough at such a range and with such fast moving birds.

      At this point panic set in. In my past swift studies I had located three swifts with white rumps, one with a white belly and a couple with a variety of white areas elsewhere in the plumage but this bird looked too precise and distinct to suggest an partial albino swift and its immediate jizz was more reminiscent of a Little Swift. I needed to get a closer view but the options were all fraught with problems and all relied upon the bird staying put which given the fast moving thunder showers and the rapid movements of swift flocks in association therewith, seemed hopeful at best. Of the three possibilities a run/walk along the 1km of bank would have left me one, exhausted and two having to walk that distance back plus more to alert other observers; driving 1.5 miles round to the next access point westwards would get me about 300m closer but take a good 5 minutes and driving right round to the location where the bird was feeding, a good 5 miles by road would take at least 10 minutes but would pass close to a phone box en route. Option two won and after a quick 200m jog back to the car I raced down the rough tracks to the ski pit access and quickly relocated the swift albeit still 700m away. At this range with a 30x scope however, I could see a broad white rump, short square ended tail and shorter more rounded tipped wings than the nearby swifts. I was convinced it was a Little Swift, not considering any similar African swifts, and thus set off on the 5 mile epic to get even closer. Calling at a phone box (this was pre-mobile phones) on the way I suffered a complete mental block on phone numbers and with just 30p in change got one answer phone, a very dippy pager operator and a BLNE answer phone where I left a message to the effect that I thought it best going out as a probable until I made 100% certain; shadows of large seagulls hung over the phone box. Eventually arriving by the sailing pit at about 15-10 hrs a desperate search failed to turn up any sign of the bird and 10 minutes later it had still not materialised. Then suddenly there it was low over the Humber bank, coming towards me in bright light backed by a black sky giving unbeatable views. It fed over the water on pit25 for about 20 minutes and then as the sun came out it began to climb with the swifts and I lost sight of it as it passed across the sun. At this point no-one I phoned had appeared and nothing had come on the pager so I begged the use of a phone in the sailing club and rang birdline. Again no response! I thus returned to the bird and failed to relocate it by 15-50 but then it again appeared over the pit where I watched it to 16-04 when it again disappeared. With still no response from any birders I decided to return home and ring round more people plus I had my daughter to collect from nursery and due to the mental block could not remember when!

     Back home at 17-10 hrs a phone call came in saying the swift could not be found in spite of 30 minutes searching. I headed back down to the pits on my bike and just as I arrived it was relocated flying back in from the Barrow Haven direction. It was then seen almost continually with odd short absences until about 19-15 (I left the site at 18-40) when heavy rain set in for over an hour after which it was not seen again.

   The number of swifts present on 26th was certainly higher than in recent days with over 500 estimated compared to about 300 over the last 2-3 weeks and it would appear that the Little Swift arrived with a mobile flock of common swifts in association with the thundery weather system affecting the area at the time.

Marsh warbler (not this year)



thoughts of Marsh Warbler brought back memories of the 1997 long stayer at Far Ings upon which I wrote a small essay produced here for reference! In the last two springs I have come across a couple of Marsh warblers at Phasouri in Cyprus in early - mid April; the distinctive and repeated call is the thing which draws attention to them when they are foraging on the edge of the reedbed; a couple of photos attached from April 2008

The Marsh Warbler at Far Ings, Barton, May-June 1997.


Somewhat surprisingly given the successful nature of the early 20th century ornithologists, notably Caton Haigh, who bagged several rare species of warbler on the Lincolnshire coast, including the first British Greenish and second Lanceolated, there are no historical records of the Marsh Warbler in Lincolnshire prior to 1961 when one was trapped at Low Farm Tetney on October 8th.


The following record, a singing male trapped at Bardney sugar beet pits, stayed from June 14-22nd 1964 and set a longevity record for residence in the county which stood for thirty three years! This bird also fell into what quickly became established as a regular occurrence pattern of singing males arriving during early June as spring overshoots from their main breeding range on the near continent and in particular Scandinavia, where the breeding population underwent a rapid expansion from the 1960's. The following seven county records all occurred between May 28th and June 5th, a remarkably restricted period, with the exception of a very early bird at Theddlethorpe on May 17th 1980. All were found on the coast apart from two which were discovered at Messingham Sand Quarries from June 4th -10th 1983 and on June 3rd 1985. The first bird had located an area of suitable breeding habitat on the northern slope of the old sand workings where a growth of nettles and willow herb was set amongst invading sallow and willow scrub on the edge of a phragmites reedbed. The latter was far more unusual in favouring a small clearing, again with nettles and willow herb, but in the middle of a plantation of 5m high corsican pines. Autumn 1986 produced a well photographed bird at Saltfleetby on August 24th in a fall of Scandinavian night migrants and further late autumn birds followed at Chapel Point from October 22nd - 23rd 1988 and at Skegness on October 16th 1993. The spring of 1992 proved to be a classic period for the occurrence of Scandinavian overshoots with regular periods of south-easterly winds from mid May to mid June. Not surprisingly several Marsh Warblers appeared on the east coast with a record 35 in Shetland. Following a singing bird at North Cotes on June 7th the first for Barton pits was a singing male which took up residence in the Humber Bridge viewing area pit from June 8th - 10th. Again it had found a piece of suitable habitat with nettles and willow herb growing amongst some stunted dead elders on an island surrounded by phragmites. In spite of regular searching after the 10th this bird was not relocated and thus the appearance of a singing male in the scrub by the pursuits centre track on June 16th most probably involved a second individual especially given the large number of birds arriving on the coast at this time. The most recent Lincolnshire bird prior to 1997 was a bird singing briefly at North Cotes from May 24th - 25th 1994 in the same bushes frequented by another Scandinavian overshoot a male Rustic Bunting.

   The spring of 1997 was a poor one for observers of bird migration which meant it was a good one for the birds which were undertaking the migrations! Long periods of high pressure enabled birds to navigate successfully and arrive back on their breeding grounds without displacement. A count of singing male warblers around the Barton-Barrow Haven pits over the period May 15th - 17th produced totals of 353 Reed, 98 Sedge, 80 Willow Warblers, 90 Whitethroats and 35 Blackcaps indicating a good arrival of summering birds with only Lesser Whitethroat at a mere 12 males being well down in numbers. Further sample counts during late May however, showed that a later arrival had increased numbers considerably in the latter days of the month with up to 20% more Reed Warblers present in some areas, 100% more in one pit, and a few more Sedge, a late increase in Lesser Whitethroats and a new Grasshopper Warbler also arriving in Westfield Lakes on May 30th.

    At 05-35 hrs on May 31st while crossing the south meadow from the car park at Far Ings I heard a few fluty notes followed by a rapid musical chatter. It sounded a bit Marsh Warbler like but not very loud. Could it be a newly arrived Reed Warbler mimicking? A return to the car park however, quickly revealed the songster perched in full view on the burnt-out front of a large hawthorn in the adjacent reedbed. Being closer to the bird its full very distinctive song rendered it easily identifiable and good telescope views established that it showed the relevant structural and plumage criteria.

    The bird, presumed to be a male, but both sexes sing, had adopted a territory based on the large hawthorn with a periphery of burnt off brambles and resurgent nettles and willow herb set in amongst a phragmites reedbed with some old dead stems and a luxuriant growth of new green reed. For the first three days of its residence Marshy sang almost constantly with short breaks to go down into the surrounding vegetation no doubt for necessary sustenance. It sang from exposed perches high in the bush, often on top, and provided a steady stream of observers with superb views although many seemed unable to hear its superb song! It was still singing strongly at 00-33 hrs on June 1st when its quick fire renditions could be appreciated from the visitor centre over the odd can of lager! It certainly appeared to be holding a territory and was noted seeing off Reed Warblers, Blackcaps and Sedge Warblers from its favoured bush. From day four June 3rd, with increasing winds it became less obvious during the day time with long absences from its song perches but it was still singing strongly in the early mornings between 04-00 and 06-00 hrs at least. It now sang more frequently from lower perches in the brambles and reeds and less from the hawthorn.

    Marsh Warblers are known to be incredible mimics and will copy the songs and calls of a wide variety of other species.  On June 5th in the early morning 05-30 to 06-00 hrs I attempted to identify the species which Marshy was mimicking. I managed a total of eighteen species and I am sure there were others but at times it is sometimes difficult to know whether you are listening to the Marsh Warbler or the real bird; they are that good. The following were picked out; Blackbird, Song Thrush, House Sparrow, Magpie, Tawny Owl, Common Tern, Nightingale, Blue Tit, Great Tit, Sedge Warbler, Reed Warbler, Blackcap, Willow Warbler, Goldfinch, Chaffinch, Starling, Swallow, Greenfinch. Some of the species like Blackcap, Blackbird and Common Tern were represented by alarm calls only. Of interest was the reaction to a female Blackcap which approached the singing Marsh Warbler on the top of the bush. Turning to face the Blackcap in threat posture it uttered a fine rendition of Magpie calls no doubt intended to be more intimidating than its own calls!

   Identification of a singing Marsh Warbler is relatively straightforward but note that Blyth's Reed Warbler's song is quite similar and it is also an expert mimic. Apart from song the Far Ings Marsh Warbler displayed the following structural and plumage characteristics which identify it from Reed Warbler. Long winged appearance created by eight pale tipped primaries visible beyond the longest tertial; contrasting wing with dark centres and pale fringes to tertials and dark alula with narrow pale fringe, the darkest part of the wing. Rounded head profile with spiky rear crown when singing and pronounced jowl. Short but obvious white supercilium which bulged slightly before the eye and faded quickly behind the eye; notable pale eye ring. Distinct olive tone to whole of upperparts in sunlight with slightly more buffy rump. Silky white chin and throat contrasting slightly with pale buff wash across upper breast and along flanks. Stout blunt tipped bill mostly yellow with dark ridge to upper mandible and a dark tip to underside of upper mandible tip when singing. Bright orange inside to bill and gape, open wide when in song. Pale straw coloured legs and feet. Iris mid brown.

   By June 7th the Marsh Warbler became very elusive and could easily have been overlooked. It moved its location slightly to the periphery of a patch of willow, hawthorn and bramble scrub on the edge of the reedbed, and appeared to have ceased singing. A singing Reed Warbler had also moved into the same area and another pair of Reed Warblers were nest building in the Marsh Warblers original territory. Late on the 7th and early in the morning of the 8th however, I was convinced that I heard very brief snatches of Marsh Warbler song amongst that of a Reed Warbler. Was the Marsh Warbler doing a perfect mimicking job of a Reed Warbler or had a Reed Warbler managed to copy some of the Marsh Warbler's song? With less wind and a cooler morning on June 9th I positioned myself in a spot from where the Marsh Warbler's territory could be observed and from 05-30 hrs stood and waited. Again very brief snatches of Marsh Warbler song appeared to be coming from its new location along with regular Reed Warbler song but no bird was visible. While watching the pair of Reed Warblers nest building in the reeds adjacent to the hawthorn a third bird started to chase them and then followed them around. At one point it broke off perched up on a dead reed and sang well. It was undoubtedly the Marsh Warbler. The song and all the plumage features were clearly heard and seen. What appeared to be happening was that the male Reed Warbler was singing occasionally and the Marsh Warbler chipping in with odd notes and very short song bursts while following the pair of Reed Warblers. It did not seem to have a mate but was obviously interested in the female Reed Warbler!  Following a few days with little attempt to ascertain if the bird was still present, on the evening of June 18th it was heard singing well from the hawthorn scrub adjacent to its initial territory where a Reed Warbler and Blackcap were also in song.  Given that the Marsh Warbler had apparently ceased to sing on a regular basis however, it was impossible to ascertain just how long it stayed at Far Ings but it became the longest staying bird of its species in Lincolnshire.

It suddenly occurred to me that Whiskered Tern was in fact a new bird for what is probably my most valuable list that of species self found in Britain and Ireland; this list gets very few additions nowadays so it tends to be forgotten; so a quick check revealed that the list stands at 324 species in the combined Britain and Ireland and 322 in Britain (Fea's Petrel and Wilson's Petrel found only from the famed Bridge's of Ross)

the Whiskered Tern was also a year tick of course in the Scunthorpe area where that tally has risen to 173 with Nightjar and Common crossbill also recorded in the last week

No shots of the Barton Whiskered Tern so a couple of retro shots from the Coto April 2003 digi-scoped -- those were the days

another tick just when it looked like spring was over

I have often surmised that finding rare birds is 70% luck, 25% chance and 5% effort; thus today was another in the long run of spring hopefuls; with rain forecast for the morning it was pure chance that I woke early, after  alate night, and strangely thought that it looked bright outside so without actually checking I was up and ready for some birding only to discover that it was actually dull, dismal and raining! having got up though I donned the waterproofs and set off for a walk around the 200ha of rough fields at East Marsh farm which has thus far this spring produced absolutely zilch but must surely be due a goody; 2 hours later, drenched and a bit peed off I headed for the adjacent pits where there was a big gang of low flying swifts to look through for that needle-tail; no needle but on sailing pit, right at the far end was a black tern with the two Little Gulls; oh well a year tick but even at 600m the upperwings seemed rather silvery and the underwings contrasted with a blackish looking belly and breast; with only my bins it was difficult to be sure but the bird looked to have white cheeks and a black cap -- suddenly it dawned that this was indeed a Whiskered Tern, first for the patch and only my second in Lincs; a frantic walk through chest high, very wet vegetation and I managed to get a much closer view which confirmed beyond all doubt that I was not dreaming; after a few phone calls the bird was still feeding and I headed off to get my car and camera; returning 15 minutes later it had gone!! so I looked around the adjacent pits and then suddenly it was back but within 3 minutes it disappeared again never to be seen again; So a classic case of chance, could well have had a lie in in the rain, could have been 20 minutes later at the pit and missed it altogether, could have chosen to go and sit in a nice dry hide as it was raining etc etc --
The result though species 251 on the patch list and 245 on my patch tally taking the year total to 148; and June's not over yet

springs a bust

to use the American term after the early promise of the Firecrest and Night Heron the later spring has been a total bust on the patch without a single scarce or rare bird being found in spite of the huge number of hours put in over the last 6 weeks, but that's patch watching for you and something that one off visitors never understand when they turn up for the one rare bird you find in 2 years! So unless the summer and autumn undergo a dramatic change in fortunes then the year list looks like being rather average and mediocre but who knows there could be a singing Blyth's Reed tomorrow! 
For the last week I have been slowly biking round all the pits every night and often morning as well listening hard for a sound of a Marsh or Icterine Warbler but the only new arrivals seem to be a couple of singing male Turtle Doves. During the last major east coast Icterine arrival in 1992 I was playing football with the son on June 8th in the Humber Bridge viewing area when I heard a singing Marsh Warbler in the ponds to the west; maybe I should A) take up football again or B) get my ears washed out; that bird stayed for two days and I found another on the 16th; in 1997 I found another singing male at Far Ings on May 31st and it stayed through to at least June 18th by which time it had stopped singing so it could have been there all summer. These are the only patch records to date and there has never been an Icterine but given the rarity of that species in recent years in autumn it is maybe not surprising and a spring vagrant may well be a better bet. 
The only area record of Common Rosefinch also came in June (4th 2003) when a singing male gave me something of a surprise at Barrow Haven station; that bird never did show itself but as I followed the song through the hawthorns it moved off east and was never heard again; 
Barrow Haven was a locality where I spent 5 years in the late 70's picking up a passing pratincole sp, Ring-necked Duck, two Nightingales, Montagu's Harrier, regular seabirds and a host of scarce migrants while supposedly working--which reminds me I do need to do some work now

scunny additions





no new birds on the patch today but over the last two weeks the Scunny list has risen to 170; the key bird was a Broad-billed Sandpiper found in a restricted area at Alkborough on the 16th by a local birder I was able to see the bird during its 3 hour stay that night; Greenshank, Wood Sandpiper and a flock of 5 Temminck's Stints have been additional year ticks but strangely I have still not had a Greenshank or Green Sandpiper on the patch this year. Some appalling record shots of the BBS above.

147

a singing male Spotted Flycatcher on the traditional territory in Baysgarth Park today was out competing the Barton Town brass band and took the tally on to 147 but still without any significant May migrants

subbuteo at last

a long overdue Hobby dashing by this afternoon broke the monotony of a total lack of anything which could be considered a new arrival; so far May has failed to produce anything scarce or rare which may mean that the month end score is one of the lowest on record contra the April result; 146

one more wobbler

at best we usually have one Garden Warbler territory around the pits each year so the return of last years male to its territory on Waters' Edge was a pretty obvious sign that it was the same bird; but still no real May goodies 145

two new waders and a near miss

Grey Plover and Bar-tailed Godwit were patch year ticks today but I was left wondering if I overlooked the big one two days ago when I only gave the Dunlin flock on Chowder Ness a cursory scan with bins while avoiding the drunken yobs in the car park---Broad-billed Sand would have been a patch tick! 144

a May mega

after a ten day break in Ontario I might have expected to add a few May goodies n return but the only addition today was a drake Red-crested Pochard! additional wildfowl were Velvet Scoter and drake Scaup adding to the wintery feel; the 13 2cy Little Gulls were a sign of hope but I have still only seen Common Tern on the patch this spring; 142

last regular




a singing male Cuckoo this am completed the expected April migrant set and took the year list to 141; also around the patch today were 8+ Wheatears including a fine male Greenland and three other possibles, 3+ Grasshopper Warblers, a new female Ring Ouzel, a singing male Turtle Dove and 44+ Swifts with the first 13 over my garden this evening. The Great Grey Shrike was still present on the heath along with a pair of ouzels and a few wheatears in what was obviously  wheatear fall day; 161
