A very distant offshore view (pooly phonescoped) of a bird which I saw dive, and which my field notes tell me had white flanks. Seen 25th March.
Any ideas at all?

PS. My wife indeed thinks it's Nessy, and she's Scottish :-O
I was originally of the opinion that it was a Diver not a Cormorant, esp. with the white flank. On this image the neck looks pretty uniformly thick to me.
 
Dave, is it looking to the right, or away from the camera?



Either way its still a Cormorant. Look at the even dark colour, the square pale area at the bill-base/cheek, the pale bill. Its neck looks thick because its swallowing a fish - you can see its become thinner again close under the head, no diver would show that. Finally, an adult Cormorant at this time of year has a very distinct white flank patch.
 
Hard to say which diver but I get the impression of dark on the hindneck, and a rather pale throat from the slightly uptilted head, the former if not just shadow would suggest red-throat which is by far the commoner diver in Irvine Bay.

Cheers,
Andrew
 
Cormorants can look thick necked at times.Ihave known them to be mistaken for divers on numerous occasions by birders.The bird in the pic appears to have the white face markings of a Cormorant.Also when they are swimming they lie low in the water like the bird in the pic.

I'm afraid I can't tell you which way it's looking, since it was one of those "quick, get nearest camera to hand" photography efforts. However, I did remember getting excited about it, which I don't think I would have with Cormorant. The sea was pretty calm.

Question: Shouldn't Cormorant have a sloping tapered back, not the short stubby one like this?

For the record, I wrote in my notebook Diver sp? Red-throated?, and then crossed out Red- and wrote Black- :eek!: :-O

I won't mind too much whatever it is since I've seen both these Diver species much more closely at hand before so no tick is riding on it. Pity!

I've had another long look, and can't combine diver with the blue-green glossy colour of this bird. Angle can be a tricky thing - it makes shapes change drastically - which was why I asked which way it was facing. An adult diver would have a darker throat than nape, an immature a white throat, both would stand out through the scope at that range [the phone reproducing much less than the eye would have seen].
 
I agree-enlarge the image sufficiently and you can see its a Black Throated.

I'm curious to know what extra detail you can see by enlarging the image. Personally I can't see it's a Black-throated whether I enlarge it or not. If it is a Diver then the unfortunate quality of the photo has masked it so well that it looks more like a Cormorant.
 
White-billed Diver ...

Actually I'd go further and say it's probably a hybrid White-billed Diver/Surf Scoter/Pied-billed Grebe, in other words, it's probably a Cormorant (or a Black-throated Diver) either of which of could show a 'white flank patch' ...
