On Saturday Bjørnar Skjold reported a Collared Flycatcher on Skjold. Cauteous as ever, he wasn't sure at first, but when the bird was seen by other birdwatchers, people were satisfied with the ID as Collared.
But I understand Bjørnar's hesitation, because it is a strange bird. It looks like a pale male or a strongly patterned female. The bird shows itself well, but always at a distance, so it is difficult to judge all the characters. The wings and tail fit a female better than a male (pattern on the greater coverts and white on the outer tail), but the head fits a male, albeit a bleached one, with the almost complete collar and the white spots on the forehead... One can see an age difference in the wings with the worn outer greater coverts, primaries and visible secondaries not moulted yet and one year old. That makes it a second-calendar-year bird. The ID is probably alright, but age and sex have to be determined. And one must always keep the possibility of a hybrid in mind, especially with ficedula flycatchers!
During the last few days the bird has been discussed by Tor Olsen, Frode Falkenberg (and me). Tor has had contact with Johan Träff, who has ringed 1000+ flycatchers on the eastern Swedish isles. He thinks this bird is a grey-morph Collared Flycatcher, not a hybrid. He agrees that this is a second-year bird, but says that sex is better left undetermined. He has seen quite a few grey-morph females, but never a male like this...
