    Guyana Savannah

    It looks like black-billed thrush (or whatever the post-split species there is). However, ebird records suggest that's no there. Certainly a thrush...

    Spotted in a Minnesota parking lot

    Not identifiable by me at least. However I can see why you think it could be white-tailed kite (I don't think it is)

    A few from Lima, Peru

    It's a tropical kingbird. Extent of white, head colour etc

    Various Raptors - South Essex UK - 12th May

    A google of "rolling shutter effect birds in flight" (for example) provides your starting point. Has been discussed in relation to some modern, high-end cameras like Canon R5, R7 etc fairly extensively. Some of the distortions you will see are quite extreme.

    Gull, Salton Sea, California, USA 12 May 2024

    Looks like laughing gull to me

    North Vancouver - Lower Mainland B.C

    looks adult

    A few from Lima, Peru

    It was variable hawks for me. Everywhere. Surprised we have not seen pics of black vermilion flycatchers yet

    Raptor in South Louisiana USA

    Yes broad-winged

    A few from Lima, Peru

    On this basis, we can infer the primaries fall short in one of the 2 original "shiny cowbird" pictures (5), further evidence it's actually scrub blackbird. In my peruvian experience scrub blackbird's actually a pretty common urban bird

    A few from Lima, Peru

    This "west peruvian dove" looks more like eared dove to me. That also has a black neck patch but also has dark spots on the wing. I think we can see those in amongst the artifacts here. We can also see a hint of a dark line leading back from the eye (not always clear in this species). The WP...

    A few from Lima, Peru

    These 2 are a relatively recent split: "white-winged" used to cover both. The west coast birds are now west Peruvian dove The bill on 5 is difficult to assess but may be better for scrub blackbird (longer, thinner, less like an equilateral triangle)

    Winnipeg Canada - warbler? (Sparrow?)

    A sparrow (bill shape). Perhaps clay-coloured from the buffy underparts but if so duller than those I've seen.

    Besra or Shikra, Taiwan

    Do the finely barred thighs point to crested goshawk?

    Wader (Fuerteventura)

    Which means the right is in shadow {the black parts of the legs), and the left part (the "pale" part) indicates the real colour of the legs---they certainly are not black One cannot both say that the image is so full of artifacts as to be uninformative and then suggest that something as small...

    Wader (Fuerteventura)

    Yes it's about interpretation of the colour of that "pale border". I agree it's subtle (so people will disagree) but I see the colour here to be reddish or perhaps orangy---this of course making allowances for the obvious problems with the images
