    Gulls with black eyes from bird flu survival

    Been reading recently about seabirds (esp Gannets) showing an all dark iris as a consequence of getting and surviving bird flu... The attached sub-ad Herring Gull on my local beach in Mablethorpe, Lincs on Aug 11th shows such eyes.... not even any dark pupil visible, simply black. At first i...

    presumed Mediterranean x Common Gull hybrid

    Had the attached 1w Gull near Grimsby, Lincolnshire on 20th Dec 2022.... When first found (at distance) it was stood amongst BHG's and i initial thoughts was a Med Gull but was slightly confused by its slightly larger size and subtly darker mantle, it also looked to have a rather long...

    Shoveler with eye-rings. Notts, UK

    The attached Shoveler was along the River Trent at Cottam, Notts on 12/10/21 Not entirely sure what's going on but I've certainly never seen a Shoveler with eye-rings before? it was rather rufous in colouration so considered some past Cinnamon Teal genes? But size and upperwing was just as...

    Baltic pretender - Lincs 17/8

    I know unringed adults are deemed undoable however this one i had recently on my local patch of River Trent must certainly be up in the strong contender stakes.... *very small and dainty size, elongated proportions. *black mantle tone with an appreciable mahogany tint in the scope (not really...

    Swollen belly on Goldfinch

    Sorry for the freak show peeps...... but what's this one all about? I've never seen anything like it before and the best i can come up with is perhaps a swollen/infected brood patch or something?? but happy to corrected..... Cheers Dean

    head growth on Great Tit

    Anyone any ideas what this is all about?.... Not nice to see but this bird was seen daily in this state for a good 2 and half weeks before (presumably) succumbing? Rather incredibly she always seemed sprightly, always active, fed well, was seen bathing and preening regularly, the rest of the...

    presumed 1w Ring-billed/Common Gull x LBB - Penzance, 25/12/20

    Thoughts appreciated on the attached 1w that graced Penzance harbour in Cornwall for 40 minutes on Christmas Day.... Very small and dark looking and not particularly like anything i've ever seen over the years in terms of both size and plumage - things like Azorean Gull, Cape Gull, American...

    putative American Herring Gull, Devon

    A few more pics.... the comparison pic with the adult argenteus Herring in 2526 is compelling!

    putative American Herring Gull, Devon

    Can anybody tell me why this isn't a smiths?.... Just about everything about it seems good to me with the exception maybe of the black of p9 reaching the G Covs - but even that can be found on photos of birds from across the Atlantic in a relatively brief search. I was also slightly worried...

    An odd 1w Common Gull

    Whilst grilling the Gullage near Skegness on Friday I bumped into this small and dusky 1w and honestly convinced myself i was looking at a brachyrhynchus(!) After sleeping on it i have since lost a bit of faith and think that a dark canus could actually look like this but there are a couple of...

    heinei Common Gull in Notts

    Well ok then, maybe not as concrete as the header suggests but still a bloody good shout i reckon... Compared to nearby canus it differed in the following: * Larger size, especially head and bill but also longer wings which it seemed to hold slightly raised up banana style - jizz wise it was...

    Bulgarian Jackdaws - what race?

    A visit to the Black Sea coast in the SE corner of Bulgaria in September left me confused..... Almost without exception all the Jackdaws i looked at in the 2 weeks of our visit were of the grey bodied and grey mantled variety with contrasting dark wings.... a few 1cy birds lacked pale collars...

    Gull UK

    Spalford, Notts - 12/08/2018 I don't really like going down the hybrid route with tricky gulls but can't think what else this 2cy bird can be?....probably containing Caspian genes if size/structure/jizz is anything to go by (as can be seen it was much bigger than the accompanying LBB's) but...

    Redpoll - UK

    Had this very pale (almost white and grey) Redpoll briefly in my garden yesterday.... it was one of them where i wrongly sacrificed looks for images and only ended up with this one un-blurred shot and only scant views before it disappeared forever... My first thoughts were of an Arctic type but...

    Lesser Canada Goose - Cornwall, UK

    Not one to get too excited about in terms of natural vagrancy but Would appreciate any thoughts on this Lesser type Canada Goose at Drift Reservoir on Dec 12th. Apparently (although i never realised at the time) it has been present for a few months and is supposedly just a small female Canada...

    Yellow legged GBB Gulls

    Two adult marinus in Penzance, Cornwall last week with yellow legs and feet, presumably a pair (one obviously heavier than the other) as both birds stuck together over the two days they were present - the smaller female type with less black on the upper mandible had the brighter legs, even...

    Nott's Baltic Gull - about as good as it gets.....

    .......without a ring! Present in the Bellmoor Lake roost since Oct 20th when first found by Paul Hobson. Not only in terms of overall appearance but also the primary moult stage of p1-p3 renewed, new p4 not quite fully grown and p5-p10 old is highly indicative of fuscus by this date..... lots...

    fuscus? - Lincs

    Eye-catching small and pale juvenile LBB this afternoon at Norton Disney.... had a nice white-ish underwing too which can just about be appreciated in the flapping shot although note that most of the underwing is in the shade of the overhead sun so actually appears darker than it was. I know...

    large bat sp in-off the sea?

    Hi, This morning (c08;00) i had a large Bat sp fly in-off the sea at Easington, E Yorkshire. I have no idea of the species but looked much bigger and longer winged than Pipistrelles i see regularly around my house, i would estimate it about Blackbird size although size assessment not easy given...

    adult White winger - Nottinghamshire, England

    The attached was at Cotham Tip for a short time yesterday, initial thoughts were of a Glauc but on seeing it in profile i was concerned by the long primary projection and also by the extensive red around the gonys...... in flight (which was more Iceland-like than Glauc-like due to long thin...

    hybrid gull, Scarborough, England 20/01/17

    Anyone fancy sorting parentage out for this one? i guess the default would be LBB x Herring but could the broad band across p5 suggest michahellis influence? eye ring orangey red.....

    Common Gull wings, E Yorkshire 19/11/16

    possible heinei or variant Canus? nearly all black p8, broad band on p5 and smudge on outer web of p4 not a common combination for canus? ...... also decent 'spike' running a good way up outer web of p6? Cheers Dean

    Gull UK

    Another one..... Would appreciate any thoughts on this 1cy Gull taken at Spalford, Notts on 6/11/16. apologies for pics but never close. There are some very close matches on the November section of Heuglin's Gull on the GRO - not saying that it what it is of course(!) *large and powerful jizz...

    1cy Gull UK

    Anyone fancy sorting this one out? taken at Spalford, Notts on 1/11/16 casp-like upperwing and tail pattern but underwing/axills very dark, odd pattern on 1st generation tertials, random scapular moult? clean white head contrasting with streaked underparts....

    putative Mew Gull, Lincolnshire

    Had this amongst c500 Common Gulls in my local roost on Friday (28th), Subtly smaller than CG with slightly paler mantle, yellow/brown iris, broad white tertial crescent, very dense head streaking (for time of year) which was strongest on nape and extended strongly on to breast, small dark spot...
