almost certainly another one!

Heysham Obs
An excursion around the non-operational land looking for Black Redstart also involved checking the willows on the west side of the 'tank farm'. This is the inaccessible migrant 'black hole' to the south of the Nature reserve office. A Yellow-browed Warbler was located on call opposite the security lodge, seemingly associated with Long-tailed Tits. 10 seconds or so through the foliage almost certainly (therefore not absolutely 100% certainly) involved at least one view of the left leg and it was unringed. However, there was never an occasion when both legs were visible at the same time, therefore a bit of overnight soul-searching 'downgrades' this record to "almost certainly a different bird" to yesterday. The bird did also seem to have paler, less yellow-suffused wingbars than yesterday's bird but comparing in-hand and field views is not really safe. It appeared to move towards the top of the tank farm, giving a further contact call, and could not be found later

Other grounded birds
Very little vis today due to the cloud cover and intermittent light drizzle so some species such as Grey Wagtail and Meadow Pipit were grounded.
For the first time I can remember at this time of year, there were NO Greenfinch sightings during the 'normal' vis period 0700-1000 and this indicates just how high a percentage of this species in October are visible migrants and therefore absent during this morning's conditions (as also indicated by the lack of retraps):

Chiffchaff: at least 7
Goldcrest: Odd - c30 in the scrub/woodland near 1/2 Moon Bay yet very few on the reserve (less than 10).
Bullfinch - the last few days have seen occasional vis mig birds - today's birds were grounded and FOUR (a good daily total for here) were ringed
Grey Wagtail - three grounded birds (or perhaps prospective wintering birds - time will tell as two were ringed)
Song Thrush =- at least 12 grounded birds
Stonechat - male on the S end of the tank farm late morning
Meadow Pipit - 5 on the NHW mound
Robin - good numbers of extra birds with individuals hemmed in by residents on the non-operational land and also on the mound

Vis mig from next to the NR office
Very little: 5 Chaffinch, 4 Song Thrush, 5 Redwing, 3 Meadow Pipit, one Lesser Redpoll.

North harbour wall
Just one 2nd W Med seen in a quick visit and no sign of either Guillemot species

Ringing
Todays ringing included 4 Bullfinch, 3 Chiffchaff, two Grey Wagtail, a Great-spotted Woodpecker and 7 new Long-tailed Tit.

Ringing totals (excluding pulli) to date comprise the following above par: Blue Tit (85), Great Tit (34), Grey Wagtail (34), Goldfinch (48), Lesser Whitethroat (28), Reed Bunting (39), Grasshopper Warbler (12), Bullfinch (11) and below par: Robin (55), Greenfinch (96), Wren (30), Willow Warbler (73), Whitethroat (54), Redstart (1), Garden Warbler (2). This includes a mixture of migrants, CES records and late summer wetland ringing at Middleton IE. The most obvious feature this year has been the contrast between good Lesser Whitethroat numbers and poor Common Whitethroat, both breeding population and productivity. So far this autumn, there has been more movement by tit species following a run of very poor years. The ringing is organised by Alan Draper with regular help from Andrew Cadman, Jean Roberts and Pete Marsh.

Insects
Brief sunlight in late afternoon saw a few Red Admiral, 2 Comma and a few Common Darter but no Migrant Hawker.

Elsewhere
Great White Egret Leighton Moss area, also 9 Little Egret and the juvenile Marsh Harrier

More like it!



Yellow-browed Warbler ringed today. Thanks to John Mason for the photo. About 17 records here, most in the late 1980's/early 1990's when there was less vegetation to search through

There is one more day of suitable weather for birds of eastern origin. If you have some time tomorrow worth searching coastal sycamores etc. (or any urban clumps near to all-night lighting) [further arrival of Yellow-browed Warbler today with several west coast/Irish Sea island sightings]

Heysham Obs
The Robins were ticking again! Thanks to Malcolm, Jon, Dave, Jean John, John again, Shaun, Pete and a few others I am not able to name......for coverage.

Grounded
Very good coverage produced: Yellow-browed Warbler (caught in the nets next to the office at 0900hrs), Garden Warbler (a fat-looking one commandeering a bramble bush at the south end of the tank farm - probably off-passage in an area not recently checked), 15-20 Goldcrest, a least 7 Chiffchaff, including a bird giving 'soft', Bullfinch-like calls.......but looked like a collybita! Thrushes were at a premium with just c10 Song Thrush, a few extra Robin, one Blackbird acting like a migrant (!) and 3 Redwing. Two Wheatear on the coast.

North harbour wall/harbour area
The usual 5 Med Gulls were performing and the Black Guillemot was again present in at least the morning. Single Guillemot still in the harbour. Perhaps the same mobile Kingfisher was seen on three occasions between the NH Wall and Heysham Head

Vis mig from the office
This was difficult due to conversation, a minor YBW twitch etc., but the sky was kept an eye on to a greater or lesser degree from about 0730-1100hrs but a lot of stuff was so high that the totals could be as much as 50% underestimated from 0830ish onwards

Meadow Pipit - 33 SE
Chaffinch - 24 SW
Lesser Redpoll - 2 SE
Song Thrush - 4 S (ish)
Goldfinch - 17 S
Siskin - heard x 2 plus 2 seen SE
alba Wagtail - 9 SE
Merlin - female ESE
Kestrel - 1 S, 1 SE
Starling - 12 (flock) high to the south. Ignored the rest.
Grey Wagtail - 3 S
Greenfinch - 11 SW
Bullfinch - flock of 3 high to the SE
Redwing - 10 SW
Brambling - 1S
Mistle Thrush - 4 SE
Skylark - 5 SE

In addition, there was some fidgety behaviour by Dunnock with the piping and trilling calls and similarly Coal Tit but it was difficult to quantify this other than 2 unringed Coal Tit were caught.

Insects
Late autumn moths in the trap comprised: 1 Silver Y, one Green-brindled Crescent, one Black Rustic, one Lunar Underwing, one Red-line Quaker and 4 Pink-barred Sallow. Two Red Admiral & a few Common Darter Middleton IE but surprisingly no Migrant Hawker reported from anywhere today

Elsewhere
Great White Egret EM complex along with 5 Spotted Redshank. Great Grey Shrike visible from the causeway on at least two widely-spaced occasions. Cetti's Warbler seen and heard calling near to where it was released the other day = L Moss causeway near the public hide BUT the legs were not seen to absolutely confirm it was the same (ringed) bird. Up to 6 Bearded Tit were seen on the grit trays but not there early morning. 1st W Common Tern still on Pine Lake. Single Crossbill, 200+ Siskin, 50+ Lesser Redpoll & 13 Brambling Thrushgill plantation area (no general access here).

The Black Guillemot returns!

Heysham Obs
The day dawned with singing Robins. This is not good. Singing Robins mean nothing else in the bushes to chase and chastise. Good migrant mornings are accompanied by lots of 'ticking noises' and chasing sessions, including any other passerines invading the inner sanctum of bushes at the centre of the territory. This applied to yesterday when the first Robin song (as opposed to 'ticking') from those around the office was not until at least a couple of hours after dawn.

The 'vis' was far too high, the pylon was crackling making birds even more difficult to hear and there were several other birders providing coverage. Melmerby cafe (en route to work in Northumberland) seemed a whole lot better prospect than the supermarket brand "muesli" in the kitchen which doubled up as substandard mammal trap bait. Good move - secured the last ever bowl of Fig and Date Compote in 2007 (off the menu in 'winter')

North wall/harbour area
The male Black Guillemot, now in winter plumage, returned and was chased off the wooden jetty by feral pigeons and ended up in the water next to the jetty during at least the morning
Guillemot - one in the harbour still
Med. Gull - 3 x 2nd W along the north wall and two adults (one may have been the other (less regular) very faintly-marked 2nd W?) on the heliport

Vis mig from the office intermittently 0700-0900
Difficult, as described above, due to height of birds and crackling electricity wires.
Reed Bunting - 2 SE
alba Wagtail - 14 S
Chaffinch - 44 SW
Dunnock - 2 S
Starling - 32 S
Greenfinch - 5 SW
Woodpigeon - 17 SE
Meadow Pipit - 20 SE
Redwing - one flock of 16 SW
Grey Wagtail 2 SE
Linnet 12 S
Goldfinch - 15 SW

Grounded
Not much pre-0900hrs around the office. Wheatear on the NHW mound

Red Nab
51 Shelduck and the first (13) Wigeon reported this autumn
Kingfisher by the outfalls

Moths
At last! The first Lunar Underwing of the year.

Elsewhere
"Stubble burning" at Cockersands produced a Short-eared Owl along with 53 Skylark, 3 Reed Bunting and a surprising 104 Meadow Pipit. The Great Grey Shrike seen again by a reliable observer from the public causeway at Leighton Moss. What has been described as a 'grey' Willow Warbler with white underparts was trapped and ringed nearby. Great White Egret and two Avocets on the EM complex. Male Ring Ouzel at Aldcliffe

A nice varied morning of common bird migration

Heysham Obs
A nice change from the slog down to Flamborough's Old Fall Plantation. A calm, rather clear morning with a light SE wind saw a lot of migration, most of it overhead and quite high.

Vis Mig from the office intermittently 0700-1000
The alba wagtails were too high and/or not directly overhead and only 5 were definitely White. Highlights:

Meadow Pipit - 115 SE
Chaffinch - 38 SW
Brambling - 2 SW
Siskin - 31 SE
alba Wagtail - 64 SE
Grey Wagtail - 2 SE
Goldfinch - 29 S
Greenfinch - 77 SW
Coal Tit - 3 S
Skylark - 30 SW
Starling - 29 S
Blackbird - 2 SE
Song Thrush - 3 S
Jay - 2 S
Lesser Redpoll - 15 SE - Reinforcing the impression some of the birds seen/heard last week were almost certainly not Lesser were four small groups of obvious Lesser (on call & size) this morning
Crossbill - An extremely noisy flock of 9 to the SE at 0910hrs. These were heard for 'ages' in the direction of the wooden jetty before they appeared!
Reed Bunting - 1 S
Great Spotted Woodpecker - 3 separate birds appeared to be heading south fairly high and purposefully (but birds 'doing the rounds' are a regular sight)
Redwing - 2 SE
Linnet - 10 SE
Long-tailed Tit - 3 flocks totalling 51 birds S
Woodpigeon - 11 S

Grounded
Goldcrest at their highest numbers this autumn but this is not anything dramatic with perhaps 20 around early on. No phylloscs for the first time this autumn. Two Blackcap seen. Main feature was at least 3, probably 4 rapid-transit flocks of Long-tailed Tit (max. 16).

Ringing
The two nets by the office were run and caught too many birds with respect to trying to monitor high vis at the same time. Most of these were Greenfinch (c15 new ones) but included 3 Goldcrest, a rather grey, orange-breasted Robin and a continental Song Thrush. An unringed adult male Great-spotted Woodpecker caused a bit of excitement and earache!

Insects
Two Red Admiral south during the vis mig watch (early in the day for butterflies). Comma by the office later on. Migrant Hawker by the office.

Elsewhere
Great White Egret Leighton Moss area, also up to 9 Bearded Tit on the grit trays. NNEW on the late Avocet. The Bearded Tit population is very low this year with a max of c20 pairs and very poor productivity in 2007 (only 13 juvs ringed). No sign of yesterdays Purple Sandpiper at the Stone Jetty

The perfect weather!

Heysham Obs
This was a good day - rubbish north-westerlies at Heysham, so no guilty conscience, yet the self-same weather provided some nice survey conditions for our work on the Humber........and (perhaps a little fortunately, given the clear conditions and following wind for at least half the night) a worthwhile detour to Flamborough.

Nature reserve
Collisions with the pylon lines seem to be fortunately rare. This Knot seemed a little stunned but unharmed as it wandered about next to the classroom


Coastal areas
Kingfisher at Heysham Head, only the second record in many years of watching this area (not the outfalls as published earlier - this is a separate bird & was not reported today). More Knot, indeed c8,000 of them, on the heliport. Wheatear Half-Moon Bay. Thanks for these, Malcolm

Elsewhere
Welcome arrival in the form of a Purple Sandpiper by the
Stone Jetty. A late Avocet (passage, not 'leftover') on the pager for the EM complex plus a Curlew Sandpiper and the long-staying Great White Egret.

A vis of two halves

Heysham Obs
Visibility still too good to drop any significant numbers of night migrants and the large Long-tailed Tit flock failed to interest any 'Yellow-brows' which might have passed through as it was checked early and late morning. What was needed was an early morning bush searcher.

Vis by the office 0700-1000
Most of the first 1.5 hours was NE to SW finches and subsequent time mainly NW to SE Meadow Pipit and alba wagtail. The Livingstone paper was applied to the underparts of overflying albas and, providing they flew directly overhead, a good number could be identified as White.
Reassurance was found by subsequently examining the more sullied underparts of the grounded Pied Wagtails around Ocean Edge! A single call from something more interesting, but the bird could not be located in the short time you have observing the sky

Chaffinch - 58 SW
Brambling - 12 SW (including flock of 11)
Redwing - 25 S
Song Thrush - 15 S
alba Wagtail - 78 SE, 35 identified as White, the remainder unspecified
Siskin - 51 S/SW
Starling - 102 S
Cormorant - flock of 4 high to the SE
Grey Heron - one 'in-off' then high to the SE
Meadow Pipit - 51 SE
Greenfinch - just 13 SW
Pink-footed Goose - 117+60 NE, 17 SW
Collared Dove - 4 S
Carrion Crow - flock of 4 high to the S
Reed Bunting - 4 S
Woodpigeon - 5 S
Linnet - 8 SE
Bullfinch - flock of 3 high from the north, then SW, then turned SE, before joining two Chaffinch heading S! Way above pylon height
Grey Wagtail - 2 SE
Mistle Thrush - 2 SE
Dunnock - 2S
no tit movement today in cloudy conditions

Grounded
3 Chiffchaff, 2 Blackcap, perceived increase in Wren from early morning 'noise' (!), 2-3 Goldcrest

North wall
2 x 2nd W Med Gull

Other coastal sightings
3 Wheatear this evening and Kingfisher still around the outfalls

Moths
Late Large Yellow Underwing and the first (2) Red-line Quaker of the year. Why have there not been any Lunar Underwing to date?

Elsewhere
Female Cetti's Warbler trapped and ringed at Leighton Moss near the E end of the public causeway. 3rd record for Leighton and this area. Great White Egret still around. Juv Common Tern still Pine Lake.

Overnight Song Thrushes

Heysham Obs
A pre-dawn arrival saw a clear sky and no evidence of thrushes landfalling at dawn before reorientating and heading inland. This is a feature of many cloudy/misty October mornings. On the R & M day, several (continental) Song Thrushes were present on an essentially cloudy morning and these subsequently moved around at net level before departing and 4 were ringed. This morning appeared to be clear and thrushless with the only chance being high-flying vis. However, during the second hour (not the first) after dawn, Song Thrushes suddenly rose out of several bushes close to the office and headed off high to the south. A total of 21 were logged and there is absolutely no way these birds could have arrived in these bushes at or just after dawn as they were under constant observation during the 'vis' watch. Therefore the assumption is that they landed during the night (the site is fairly well lit) and took a bit of time to wake up before heading off. The difference between this morning and Saturday was the clear skies and this undoubtedly prompted the steep take-off with no chance of any being mistnetted.

Vis from the office dawn to 0930hrs
Chaffinch - 72 SW
Greenfinch - 38 SW
Collared Dove - 10 in 4 groups high to the south - a good count!
alba Wagtail - 45 SE
Meadow Pipit - just 28 SE
Grey Wagtail - 2 (one ringed!) SE
Redwing - 2 E
Goldfinch - 68 S
Siskin - 4 S
Coal Tit - 2 S
Skylark - 1 SE
Linnet - 10 SW
Dunnock - 2 high to the south
Carrion Crow - 4 high to the SW perceived as migrants
Reed Bunting - 2 S
Bullfinch - yet another high to the south
Sparrowhawk - 2 south
Not a single Mistle Thrush seen!

Grounded
A little bit more than yesterday which is not saying much. At least 4 Goldcrest, 2 Chiffchaff, 2 Blackcap, 21 Song Thrush (see above), 7 presumed migrant Blackbird, possibly more. Quite a bit of tit activity, notably an unringed flock of 35 Long-tailed Tit, but no definite irruptive behaviour other than by the two Coal Tit.

Ringing
Included some of the LTTs, Blackcap, Chiffchaff, Goldcrest and a Grey Wagtail

North harbour wall
At least 2 2nd W Med Gulls

Elsewhere
No reports of the Leighton Moss Great Grey Shrike which has plenty of places to go out of public view but the juv Marsh Harrier still present. Possible update here later. Male Crossbill over Caton Moor vis site and 4+2 Crossbill in Thrushgill Plantation but no public access to where seen [Richard's Pipit over the Rossall Point vis site]

'Difficult' vis, few grounded birds

Heysham Obs
Vis made a little difficult by a nearby generator combined with many of the birds being very high. The main species which was underestimated was probably alba Wagtail with a lot of fast-moving intermittently calling birds. The majority of the vis, unlike yesterday, comprised 'cross-bay' birds from the north-west to south east and therefore thrush species and Chaffinch were in much lower numbers. Redpoll were interesting. Very used to Lesser Redpoll flying over this site (especially spring) and there was a definite contrast between the 6 which accompaned Goldfinch = 'typical Lesser calls' and the more staccato, harsher, lower-pitched calls from the birds arriving flying very high from across the Bay with Meadow Pipit and alba Wagtail. Again, they appeared to be on the large side but no detail could be seen on them. Tape lure?....but a lot of effort for the possibility of one-two birds per hour at best.

Vis by the office 0745-1100 (NW to SE unless specified)
Meadow Pipit - 245
Redpoll - 6 definite Lesser (flock with Goldfinch) and 2+1+3+4 unspec.

A varied morning spoilt by being too cloudy, yet not low enough to drop migrants

Heysham Obs
Managed to forget the obvious - advertise the Ringing/Migration morning on this site! It was not to bad at all althought he 'vis', especially cross-bay, was curtailed by 'medium-high cloud' of the variety which is usually 'useless'. Too high to 'drop' any migrants, especially if there is no precipitation, yet thick and extensive enough to discourage vis mig. Enough grounded birds were around to provide a nice steady variety to show people in the hand, including the noisy/aggressive species!


Unthinkable even 5 years ago, rather like the Egret-fest at Leighton, 4 out of the 5 north harbour Med Gulls were in a line (with 2 BHG) - the furthest bird is the Czech-ringed adult.


3 2nd W & Ad Med with 2 Black-headed Gull. Thanks to Jon Barber. This is an e-mail-reduced pic and better ones may be available Monday.

Ringing
Plenty of species, including 4 continental Song Thrush, two (partial)migrant Coal Tit, a Grey Wagtail, a Reed Bunting, a Chiffchaff, just one Goldcrest etc..


Vis Mig
Redwing - just 4 heading NE & one heard earlier on
Bullfinch - a flock of 4 moved high to the south
Woodpigeon - 24 S
Collared Dove 2S
Jay 2S
Swallow 3S
Chaffinch 35, many of these flying north!
Goldfinch 6S
Grey Wagtail 2S
alba Wagtail 17S
Greenfinch 28SW
Meadow Pipit 16SE
Mistle Thrush 13SW


Grounded
Highlighted by a female House Sparrow - the first on the reserve this year - it eventually headed off south-west! One Wheatear on the north wall. At least 5 Blackbird looking like long-winged continental birds. c10 Song Thrush. 1 new Chiffchaff and just one Goldcrest.


Misc
4 2nd W and an adult Med Gull on the north harbour wall. One of the 2nd W was a brief visitor to the food, the other 4 birds remained and landed together (see photo).
Guillemot in the harbour


Middleton IE
Increase to 25 Tufted Duck, also 8 Teal and a female/imm Stonechat


Elsewhere
Great White Egret Leighton Moss. 5 Barnacle Geese and a Purple Sandpiper over the high tide at Pilling Lane Ends [& 2 leucistic Pinkfeet]. Adult Arctic and juvenile Common Terns on Pine Lake (brief visit - may have been more). Two Scaup at Teal Bay. Wagtail roost at Melling in maize saw c50% White on birds trapped using the 'Livingstone criteria'. The Whites were almost all identifiable on "feel" in the hand i.e. smaller than Pied as borne out by wing length and weight.
