    European buzzard or Common buzzard

    Looks slitted to me, though admittedly not possible to confirm 100% from this photo. The shape of the loral area is also consistent with Pernis, which was my first impression before reading any replies.

    How to differentiate Male & Female Crested Serpent Eagle? Sarawak, Malaysian Borneo

    In raptors females are typically larger (within a pair), even when plumage wise both sexes look approximately the same (as is the case here). The bird on the left is larger, though perhaps not too obviously. Look at the legs: the tarsi are considerably thicker and more robust (despite the...

    Cheers, and a really nice bird to start the year 🙃

    Fuerteventura Wasps?

    1st one is a Philanthus species (possibly e.g. P. triangulum, aka Bee Wolf, but I don't know what other possible species are in the Canaries), 2nd is a Polistes sp. wasp.

    Tern and ? Phuket, Thailand, Nov 3

    Agree with all of this. On the 2nd pic I'd say the wader on the left could be a Charadrius, but with no confidence at all and it may well be a Calidris as you say.

    Yellow Wags migrating: video

    Indeed. It's really impressive how close to the waves they are.

    Yellow Wags migrating: video

    Amazing video of Yellow Wagtails migrating at night over the sea from the UK to Northern Spain. Mesmerizing. Filmed 120km N of Santander from a vessel, last 16th September (perhaps this has been posted elsewhere, if so appologies).

    Warbler, Northern Greece

    To me it looks like it may be sunning, but I don't see any obvious evidence of wet plumage (not at all to be honest). It may also be that it was photographed in the split second before taking off (or just as it's taking off), hence the blurred bits. Just speculation. Spotted Fly regardless.

    Warbler, Northern Greece

    I don't see signs of bathing, unfortunately.

    Warbler, Northern Greece

    By the head (shape, pattern, colour).

    Warbler, Northern Greece

    Agree with this. Also the tiny feet rule out warblers, and being dark adds to it. Spotted Fly.

    Panama fruit feeder

    I think there was sort of one in the Cornell website where the livefeed is (was?) also available, but I haven't checked lately.

    New paper: Navigation by extrapolation of geomagnetic cues in a migratory songbird

    I'd think so, yes. I'd also think that if a migrating bird's natural capacity of sensing magnetic cues is impaired (due to anthropogenic factors for example, or from a natural disease or an unfortunate mutation) then you may have it getting badly lost. There's definitely some clear...

    Butterflies - Kenya

    And the 2nd is probably Guineafowl Butterfly (Hamanumida daedalus), a Nymphalid.

    What is that ?

    Hello Edwin, thanks for your enhanced photos. It's interesting how our judgement can be subjective and our perception is probably based on previous experience. For me the photos just show/confirm the 'thingy' is in fact a feather, and the whole structure can be seen there with care, albeit in a...

    What is that ?

    I agree with this. It's a misplaced feather that is just looking as translucent with the light shining through. Note the base of this "appendage" is exactly the same colour as the lower belly/undertail patch (with a bit of grey on the presumed outer web), and only gets the rosy/salmon 'colour'...

    Book for European insects?

    I have the funny feeling that either you didn't read my posts above, or that my ability to express myself in English is rather poor. Re (from post #4): I can add that not even all families are represented in the book, but those are neglectable from a beginners point of view. I do look at...

    Book for European insects?

    As jurek says, and I've said above, the book is oriented to field ID of conspicuous and identifiable species in the field, which is what the OP is looking for. There is no better single book, the alternative being to buy dozens (hundreds?) of little and very expensive books for each family. Your...

    New to the Group, Dallas ID

    Looks similarly impressive in this recent video as well (I believe in Oklahoma):

    Book for European insects?

    :D I know... But still there will be loads of Polish and Czech species in the book, the diversity should not be very different (you'll get most likely pretty much the same fauna as Germany for example). The big problem is for Mediterranean species.
