    Bean Goose - Poland

    These seem to be well within the variation of Tundra Bean Geese to me. Bills like these occur (at least at my local patch) in every 50+ individuals or so. Cheers, Lützen Portengen

    Tiaga or Tundra, near Beidaihe, east coast China 3 October 2019

    To me these pictures seem to show fairly squat looking birds, with shortish necks, shortish bills, and rounded heads, all suggesting serrirostris. Pictures like this can be deceiving, but I am struggling to see any features that suggest middendorffii? Cheers, Lützen Portengen

    White wagtail or British Pied Wagtail in Switzerland

    I think is impossible to say whether this is a Pied Wagtail or not based on these pictures alone. Even though the flanks seem a bit dusky, that is not a really conclusive fieldmark (about 20% of White Wagtails have dusky flanks according to the paper I have linked to below), and the quality of...

    yellow wagtails flavissima - identification criteria

    Flavissima is not just flava with a yellowish supercilium, and there seems to be very little else suggesting flavissima. I agree with Roland, that while some yellow in the supercilium and the presence of yellowish/greenish feathers on the crown/nape are generally regarded as evidence of...

    Tundra vs taiga bean goose

    Taiga Bean Geese for me, for exactly the reasons that Alexander mentions. The left bird is very likely to be a Taiga Bean Goose too, but one that I would have left unidentified if on its own (it still looks better for Taiga than Tundra to me in this picture). It is likely a young bird, although...

    Bean Geese - Poland

    That last bird looks like a rossicus to me (a mostly orange bill is only a supporting feature for fabalis). Agree with (probable/likely) fabalis for the right-hand bird in your first picture (looks long-necked and rather slender- and long-billed), but difficult to be 100% sure from a single...

    Goose ID help needed - Belgium

    I think you can see the black nail quite clearly on the picture where the bird is standing. The basal area of the bill usually shows more extensive black markings, but this varies just as it does for Tundra Bean Geese. Lützen

    Goose ID help needed - Belgium

    The colours seem to be off and I can't see the tail well enough, but based on the short neck, rounded head, and short bill this looks like a Pink-footed Goose to me. I guess the confusion is with Tundra Bean Goose, as the bill colour appears a bit yellowish in the first picture? Cheers, Lützen...

    Taiga or Tundra (Ottawa/E.Ontario/Canada)?

    To be honest, I don't see any features that suggest it is not a Tundra Bean Goose. I see a rather compact, greyish, short-necked, short-billed bird with a rounded/triangular-shaped (rather than wedge-shaped) head. I would be surprised if the additional/better pictures would change that view...

    Greater white front / Tundra bean goose mixed pair with one young

    Not for me. I accept that a mixed pair doesn't equate to hybrid offspring, but I think I would have called this as a probable hybrid even on its own or with only one of the parents present. Lützen Portengen

    Bean-goose ID please, tks

    I have no experience with either subspecies (middendorffi or serrirostris), but I have seen pictures of very similar birds that were called middendorffi. I would expect serrirostris to have a somewhat shorter bill and neck than this bird on average, but not sure how extensive the variation is in...

    Greater white front / Tundra bean goose mixed pair with one young

    I would have noted this down as a hybrid Tundra Bean x Greater Whitefronted, even without the parents being present. Bill colour is extremely variable in this hybrid, but it is often the first thing I notice: You've probably seen these, but...

    yellow wagtail , ssp ?

    There is quite a bit of variation in flava, at least that is what I would call it. Birds with darkish ear coverts and cheeks are not really that unusual: https://oudeversie.waarneming.nl/waarneming/view/188583360 https://oudeversie.waarneming.nl/waarneming/view/188636017...

    yellow wagtail , ssp ?

    For me the male is within the normal variation of flava. The other bird looks like it might be a Water Pipit. Lützen

    Limosa limosa islandica? - Belgium

    Doesn't look like a nominate BT-Godwit to me. Males can be somewhat tricky, but at this time of the year most limosa males are still rather pale-ish. I would put my money on an islandica, probably a female. Lützen Portengen
