    Immature gulls in the Netherlands--Lauwersoog

    Surely a Herring Gull. Brett

    Immature gulls in the Netherlands--Lauwersoog

    In my experience it's unusual for it to be so extensively pale at such a young age. I was wondering if it were a Herring Gull (although so much pale is not usual for that species either) on plumage, and I was not convinced by the bill, and I see smiths is of the same opinion Brett

    Immature gulls in the Netherlands--Lauwersoog

    How unusual is it for a juvenile GBBG to have just an extensive pale bill-base? Brett

    Juvenile Herring Gull, Flamborough, England

    Hi Lou, I was torn between GBB and Herring Gull, but in the end I just didn't think it looked right for GBB. A puzzling bird. I missed seeing it fly off. Brett

    Juvenile Herring Gull, Flamborough, England

    I photographed this bird today, 2 November. Still has juvenile scapulars. Because of this and the tertial pattern I reckon it's a nominate bird, but what do others think? Brett

    Great-tailed or Boat-tailed Grackle? Nolton Haven, Pembrokeshire, Wales.

    I know, that's why I've been querying it. Brett

    Great-tailed or Boat-tailed Grackle? Nolton Haven, Pembrokeshire, Wales.

    It was dull. Some of my photos certainly exaggerated the blue, but a blue tint to the mantle could be seen with naked eye or bins, even in those dull conditions. Brett

    Great-tailed or Boat-tailed Grackle? Nolton Haven, Pembrokeshire, Wales.

    Can't really see it myself, and the females in the Audubon guide gallery don't really show a blue tint to the mantle that I can see, not like the Nolton Haven bird anyway. Images in the Cornell Lab website show a blue tint to the scapulars and coverts, but I haven't seen an image of a female...

    Great-tailed or Boat-tailed Grackle? Nolton Haven, Pembrokeshire, Wales.

    I asked on the other thread if females can show the blue tint to the mantle etc, but no-one has really answered this. Brett

    Red-tailed Hawk or hybrid, Flamborough, England

    Thanks for your replies. A pity the bird was always really distant. I guess it will have to remain unresolved. Brett

    Red-tailed Hawk or hybrid, Flamborough, England

    This looked OK for an adult Red-tailed Hawk from the rear, although at times the cere appeared (pale) yellow. As far as I can gather, only juveniles have yellow ceres. From the front though, as well as the broad dark bar across the belly, this bird also has a broad dark bar across the breast...

    Harris's Hawk or hybrid, Flamborough, England

    Thanks Ratal. I don't know much about Harris's Hawk but thought it was OK, but hybrid has been suggested by others. Brett

    Harris's Hawk or hybrid, Flamborough, England

    This juvenile presumed escapee has been around since 2 October. Pure Harris's Hawk or hybrid? First image by Andrew Allport, the others are mine. Brett

    Skuas sp in Yorkshire

    See what you mean about the barring, but the pale primary tips are pretty inconspicuous, and the bill looks heavier than an Arctic's to me. How about a Pomarine? Brett

    Caspianish Gull, Flamborough, England, 7 September 2023

    Thanks Steve, I always thought it was 1cy, and Caspian x Herring Gull does seem the best bet. Re. the Booby, it would have been nice to have got closer views at Flamborough. I don't think it was ever closer than 3 miles, hence the delay in putting news out as a definite. I did get better...

    Caspianish Gull, Flamborough, England, 7 September 2023

    Thanks guys for your replies, and certainly no offense Alexander. As it doesn't really fit anything well (which is why I wrote Caspianish), a hybrid seems a good bet. I look forward to further comments. Brett

    Caspianish Gull, Flamborough, England, 7 September 2023

    I'm puzzled by this gull. The bill colouration is strange, and a lot of white at the tips of the tertials. Didn't see it in flight (drifted south into the sun), but in a brief wing-lift the underwings were palish. I'd be very interested in others' opinions. Brett

    White immature Whooper Swans, Flamborough, England

    I was puzzled by the young Whooper Swan in the first image, taken on 17 December 2019. An apparent 1st-winter with all-white plumage. Today, 31 January 2023, there was a similar bird in a group of 7. This consisted of 2 adults and five immatures, including the white bird in the second photo...

    Gull, Flamborough, England

    Hi Lou It was mainly the bill I was concerned about, indicative of a hybrid?. I also thought the white primary markings were small white tips rather than just a fringe round the tip, which if so would presumably make it 3w. My best guess was 3w Herring Gull or hybrid. Brett

    Different opinions on this gull, photographed on 4 November. Thoughts welcomed. Brett

    Strange large gull, Flamborough, England

    Hi Steve We didn't think it was Yellow-legged, and L B-b Gull does seem the best bet, but I would like to emphasize that the uppperpart pattern was like nothing I have seen before, and I see plenty of young 'Leebs'. Perhaps the photos don't make it look as distinctive as it did in life. Cheers...

    Strange large gull, Flamborough, England

    This gull was called as a Yellow-legged type, but there were some strange features, most noticeably the 'spangled' upperparts. As well as the broad fringes to the upperparts feathers, the basic colouration was 'black and white' like a young G B-b Gull rather than the brown and white of young...

    Pied-type Flycatcher, Trevilly, Cornwall, 2 September 2022

    Got one shot of this bird before it flew off, and didn't see it again. Looked at the photo later that night and noticed the median bar, but I knew Pied could show this. Had a look at the Birding World articles when I got home today (3rd) and I'm very concerned about the narrow tertial fringes...
