    ID Help - American Black Duck?

    Not a pure mallard either with that dark flank pattern (which differs from dark domestic ducks flank pattern) and with yellowgreen bill and black uppertail coverts

    Kenya, January 2025 - A wader & gulls

    To me that looks much like a young greyheaded with the leg color + the shape and coloration of the dark spot and this bill- though not 100% definite proof without primary pattern, as Lou stated However , looking more closely at the single bird and the underside of its primaries: That has to be...

    Owl from Tajikistan

    You are right, but in SEO it is clearer than in LEO, and with this foto quality and a bird in movement for me it could go either way to LEO or to Eagle Owl... compare: https://images.fineartamerica.com/images/artworkimages/medium/2/1-eurasian-eagle-owl-flying-mark-hunter.jpg...

    Kenya, January 2025 - A wader & gulls
