Here's another Least Flycatcher in a more typical view, showing the relatively large and rounded head typical of the species, the short primary projection and the classic eyering which extends out into a 'teardrop' at the back of the eye.
Not a great picture due to poor photographic conditions deep in the woods, but here's an Acadian Flycatcher, taken on the breeding grounds at Belleplain State Forest, Cape May back in the summer. Though the bird is half hidden, this picture does show nicely the long primary projection typical of Acadian Flycatcher - compare with the 'stumpy' Leasts above.
Well, hopefully, if you're in the UK, this has been food for thought if you saw the Blakeney bird! All the pictures of that bird show an absolute classic Alder Flycatcher which - as Michael O'Brien so rightly said to me the other day - is harder to tell from Least than Willow when it comes to plumage, while the structure sorts Alder from Least easy enough. Sorting this group has been a long time coming, but most birders here at Cape May deal with them well enough. Right, that's the dull little birds done, there'll be some more glamorous birds in the next post I hope!!
