    Eurasian Teal/Green Winged Teal Hybrid

    I've seen one in the field that had both stripes, as shown in one of the images in the gallery Paul has shared.

    Cornwall, black head. White stripe on wings, could this be something different or just a crow with unusual markings?

    https://www.birdforum.net/threads/crow-with-white-bars-on-wings.184920/ And here is a discussion of it 15 years ago on here.

    Just one example of a google search result where the potential dietary cause is mentioned.

    Is this a non UK redstart?

    Exhumed perhaps rather than hijacked given it's been dormant for thirteen years...

    Is this a non UK redstart?

    Woodpigeon head = "Redstart face' Woodpigeon white nape and pale shadow on upper forewing = 'Redstart white forehead' Does that help?

    Increasing dissent amongst birders regards taxonomic changes and seeking an alternative listing authority?

    I 'found' a Green-winged Teal in Dublin on Saturday. It turned out that it had been seen there for a few weeks, which was reassuring as my observation was from a moving ferry! Anyway my point is that it didn't feel any less enjoyable as a birding experience because it has been 'lumped', it was...

    Male hybrid Mallard x ? Casablanca, Morocco, 16/03/2025

    This may well be correct but I thought intersex birds were females developing male features and the real giveaway was a female like bill, this bird has a bill which doesn't look female.

    Visiting Outer Hebrides and St Kilda in August 2025.

    There are at least three field guides that only cover species occurring in Scotland, which might help narrow down options. Looking at the RSPB guide on Amazon it doesn't include things like Cirl Bunting and Dartford Warbler for example, and it was revised in 2018 so should be fairly current.

    Cormorants - River Thames, Limehouse/Shadwell, London, March 2025

    Here is a good reference on the distinctions, and the fact that some are less clear cut.

    Cormorants - River Thames, Limehouse/Shadwell, London, March 2025

    There are two subspecies of Great Cormorant we see - carbo and sinensis. Sinensis were visitors from the Continent but both now nest here. White head and neck feathering was thought to be a sinensis diagnostic feature but it isn't now. In London both subspecies are possible but you need close...

    UK White Storks

    Hi Phil, Are these birds ringed? For more years than I care to remember the issue with potentially wild White Storks in the north of England is that both the Harewood House, Leeds and more recently Dalton-in-Furness birds have been a mix of ringed and unringed. Stephen

    UK White Storks

    I would say it's less odd now than it was. Now White Storks are being released elsewhere it feels less of an issue that the Dalton birds can wander as far as Scotland unchecked. Previously a zoo that had been prosecuted for not keeping its population of Sacred Ibis in check was being allowed...

    Duck hybrid, February 2025, Austria

    I think it's clear we aren't going to get a definitive answer but you've highlighted one similar feature of these two birds when there appear to be more differences. Joern has detailed these better than I could. The second bird looks like a pure Pochard and the original bird doesn't.

    Duck hybrid, February 2025, Austria

    I also haven't seen one like this. Why would an aberrant Pochard have a different bill pattern? I found the Tufted x Pochard below on a bird hybrid website which looks fairly similar.
