    Large dead bird ☹️

    Pattern and direction of wing coverts are wrong for Common Pheasant, but these markings also do not seem to fit to a juvenile larger gull in my opinion? Black bill would be wrong at least for a living great bittern ... any more photos even if they do not look very different?

    Hybrid or Leucistic Canada Goose?

    irregular white patches on a pure Canada goose, not a hybrid, I think. It is blackbilled and the black neck sock seems to be sharply bordered towards the breast , also proportions of bill, head neck and body are like in the other Canada geese in the photo. All this is speaking against a hybrid...

    Possible Gadwall/Mallard Hybrid? And a couple of questions...

    normal male gadwall also to me. Bill coloration in males changes towards summer. the female on the photo with the male mallard and the male gadwall is also a clear mallard, not a gadwall! see shape and pattern of tertials and bill shape (though bill coloration in this case may resemble...

    A Great Egret with stout bill? China

    Comparing the branches with leaves (especially the not focuse done in the foreground) and the twigs in the nest in the first photo with the other photos it becomes clear this is the same nest in all photos, only ther ewas a shift of position of the photgrapher between the first and the...

    Duck at Titchwell, UK

    Just seeing this as I haven´t visited Bird Forum for a while due to workload, but I also think pochard here due to size and extention of pale area on bill

    Mystery duck - any ideas please? Warwickshire UK

    Helen, this is a definite ID . Head pattern is highly characteristic in this cross; and the hybrids appearance is confirmed by several captive bred birds with known parentage, even though there are not many photos found in the web currently (a few years ago that was different)

    Is this a red kite? Northwest Turkey.

    As Tom has said and pointed out in details, there are those characteristics that fit for the vast majority of birds. But there are some birds which just seem to fall in between and may cause discussion for individual birds. As far as I understand, there are some more eastern black kites that...

    Ducks, Toronto

    Agree on common merganser due to body shape and plain black and white coloration without the sccapular pattern of common goldeneye.

    North Devon Duck

    saying intersex means here an intersex -plumaged bird- not nenessarily a true interex. in general such interesex plumaged birds seem to be females with a hormonal problem (low on estrogenes)

    North Devon Duck

    I agree with intersex teal. they look quuite confuseing when you see such a bird first time. The rather broad flank barring does also occur in some other intersexes, for example Northern pintail intersexes, but is more rare in mallard intersexes

    I forgot to say - I have seen this type with the patterned speculum only in female birds so far...

    Domestic Mallard hybrid, 27.03.22 Juist, Germany

    Mallard with domestic duck genes. I don´t think this and many others are true domestic ducks, as they are in build and size just like standard mallards. Most true domestics have some differences in shape and/or size. There are also breeds which are very close to mallard, for example this one...

    Large gull, Braunschweig, Germany, 3 April 2022

    Interesting, thanks Lou. I was mainly confused because it was slightly darker than all surroundig large gulls- but the difference wasn´t large. And it certainly doesn´t seem very dark on these photos...

    Female Anas crecca with unusual blue speculum? South Romania, April 2022

    Just the angle of light. It is a female A. crecca. Under specific conditions an Anas crecca speculum can appear quite blue, but in most conditions it is clearly green.
