- 1w Caspian Gull Showed well in the main yard and then on the 384 roof. Same bird as yesterday, it has the orange staining at the base of the bill on the left side of its face.
- Yellow legged Herring Gull Superficially it looked like an Argenteus but the white proportion on the primary pattern suggests otherwise.

In relation to Tuesdays sightings post, it transpires there was a 3rd individual in my images that I thought couldve just been the 2nd bird. The thing is now, do I think its a Yellow-legged Gull? Well I thought it looked like one the other day hence why I took the photo, but unfortunately I didnt see open wing, and its probably unwise to confidently identify it from the image. I will look for it again in the meantime.
- 1w Caspian Gull Nipped out of work early afternoon on my lunch, but like an idiot Id left my SD card at home after transferring some images to my phone yesterday so only managed a poor iPhone shot in fog, but I think you can see what it is. Will try again tomorrow at some point.
1st individual a bit on the small side, bill not the heaviest, possibly female, legs a little bit on the wishy washy side, mantle shade and primary looked to be ok. Got a good flight view too.
2nd bird a bit larger, heavier bill, bit of faint head streaking on this one, legs more obviously yellower, good view of open wing on 384 roof.
Sun 5th Jan. Early morning visit and some decent birds around.
- 1w Caspian Gull Same individual as 1st & 3rd Jan, showing well in the yard. - c60 Fieldfare low over east - small flock of c15 Redwing west - 1 Raven over
Gulls. - Probably c300-400 large Gulls present, vast majority being Herring Gulls and unidentifiable 1ws - c40+ Argentatus Herring Gulls - 41 ad Great Black-backed Gulls - 4 ad Lesser Black-backed Gulls - 4 Common Gulls chasing Black-headeds - 100+ Black-headed Gulls
- 1w Caspian Gull I wasnt going to post this one but events unfolded that made the identification a bit safer so to speak. I was toying with 1w Great Black-backed due to large size, long legged, fairly heavy looking bill, whitish head but some streaking, but something wasnt right. Caspian crossed my mind but I dismissed it and started leaning towards 1w Yellow-legged Gull. Thats where I got stuck and wasnt sure at all. But looking at the greater coverts on images of the bird below and from the 1w Caspian that I claimed on New Years Day, you can see its the same bird so Ive got to stick with my 1st Jan conviction as a 1w Caspian.
Sun 22nd Dec Early morning visit before the gospel churchgoers.
- adult Yellow-legged Gull on 384 roof - 2nd winter Caspian Gull appeared later - 21 adult Great Black-backed Gulls (also 1w & 2w) - 20+ Argentatus Herring Gulls - 2w Herring Gull with the half eaten blue fabric sticking out of its mouth, its been like that for over a week now
Sun 15th Dec 2 hour stint this morning in dim and murky conditions but still some decent birds around. Decent numbers of Argentatus Herring Gulls again but Ive only stated what I could see properly, still many Gulls on BCA roof unaccounted for.
- 2w Caspian Gull again - 23 Argentatus Herring Gulls on 384 roof & main yard - Yellow legged Herring Gull probably Argenteus - Herring Gull Y:992 - 4 Ring-necked Parakeets over - 2 Redwings over - Carrion Crow with white wings
- 2w Caspian Gull again this morning, showing well on 384 roof albeit in poor first light early this morning (7.50am), nice little birthday present
Also.. - 20+ adult Great Black-backed Gulls and a nice 1w bird too - at least 15 Argentatus Herring Gulls - group of 7 Redwings over towards city centre - 2 finch-types over, sounded like Lesser Redpoll so Im gonna stick with that - at least 40 Carrion Crows around
- 2w Caspian Gull again, showing well on 384 roof and in flight
- c50+ Argentatus Herring Gulls around the site. I thought it was a decent count with at least 30 on 384 roof and in the yard, but even more were on BCA roof.
- 2w Caspian Gull present again. Spotted it with my bins on 384 roof as soon as I parked up the van but no sooner had I reached for my camera - the whole lot went up due to a gas scarer in the yard.
- 2w Caspian Gull Same individual as Thursday, probably not the best example but its got a decent enough look about it. Admittedly there is still some fine streaking to the head and to the flanks which was a concern, the bill had a slightly more defined gonydeal angle than Id like too but I cant help but feel it is a Caspian.
Also this morning.. - adult Yellow-legged Gull couldnt pin it down for a photo - 2 Ring-necked Parakeets
A very intriguing 2w Gull that I think was a Caspian but unfortunately instead of pressing transfer, I pressed erase and lost the photos. I managed to retrieve them with a special app but they are only as extension files so cant transfer them yet!
Sat 7th Dec Absolutely diabolical weather at one point mid-morning and not many Gulls around, highlight was a Grey Wagtail.
Sat 30th Nov Early morning visit at first light then a late morning visit.
- a cracking Raven over the yard - 40 ad Great Black-backed Gulls - 28 Argentatus Herring Gulls (Many Gulls unaccounted for in the way of identification as they were asleep on BCA roof so primary patterns not visible and light wasnt the best so probably a lot more) - 2 ad Common Gulls chasing Black-headed Gulls
Tues 26th Nov - Pete Kinsella & Mark Nightingale were on site, they?d had a 1w Caspian Gull shortly before I arrived early afternoon.
Thurs 28th Nov - Black-headed Gull XU42 German ringed, at Löbnitz, 10.05.24. According to the info its a male and is at least a 2CY, appears it was also reported on Tuesday by Pete Kinsella.
Sun 24th Nov A 2 hour stint early morning and although there was nothing in the way of rarities, there was a few things of notable interest. Probably c200-250 large Gulls around the site.
- Argentatus Herring Gull with yellow legs - possibly c50+ Argentatus Gulls - c120 Black-headed Gulls - 25+ adult Great Black-backed Gulls - 4 adult Lesser Black-backed Gulls - 1w Lesser Black-backed Gulls N:28J & N:46K .. difficult to tell if LBb or HG with 1w, could be either or
Argentatus Herring Gulls Obviously winter is the best time for UK Argentatus as numbers increase at various sites and I usually get a few here at Redgate, with around 20+ birds being the most Ive had. Today I counted 29 individuals which as far as I know surpasses that, BUT I have wondered why its not higher, even though 29 is a good number for this site (I was quite chuffed to be fair) its probably not even a dent in the numbers that some county sites get. Maybe I was being a bit optimistic as lets not forget its only a smallish site and NOT a ROOST where numbers will be higher. But the case might well be Im not giving them enough credibility in my identification of them. Im letting some individuals go as Argenteus mainly for 2 reasons - I think Im possibly looking for them to have more white on the primaries than whats already evident, and secondly if the mantle looks a bit on the pale side even though its got a good proportion of primary white, and yes I know there is vast variation in both races.
A realisation hit me earlier, and for the reasons given above, its only fair that I conclude there was more individuals present, so I would estimate there couldve been likely 50+ Argentatus today. Its a mistake on my part and I can only apologise for that, but hey ho - it happens.
- 1w Caspian Gull Different bird to the Redcar Tarn individual a few days ago. Showed well on 384 roof. - 12 adult Great Black-backed Gulls - 20+ Argentatus Herring Gulls - 5 adult Common Gulls

Norwegian ringed JE643, ringed as a chick in 2010 Ive had this bird at Redgate a few times in the last few years and so has Dan Gornall. Theres a long list of Norwegian sightings, but other noteworthy UK sightings include Ashworth Moor Reservoir in Rochdale and Whinney Hill tip near Blackburn.
Also of note.. What I thought was a decent candidate for an adult Yellow-legged Gull but I only got a glimpse of the open wing primary formula so Im hoping it visits again so I get a chance to properly assess it, for now it will have to be relegated to a pale mantled Lesser Black-backed, a fine looking individual all the same.
I received a comment along with an image (presumably from a Yorkshire birder) on my Twitter in response to my post regarding the 1w Caspian Gull I had here at Redgate on Saturday. Turns out the same individual was at Redcar Tarn for the last month - image below.
- adult Great Black-backed Gull with a somewhat slightly palish mantle providing a bit of contrast with the blacker primaries and its legs appeared to have a slight yellowish hue. Probably nothing unusual to the more experienced Gullers amongst us but I thought it looked a little bit odd
