Baltic Gull

Post by JanJ » Sun Jan 19, 2020 1:46 pm

Mars!
This Gull was photographed in Cyprus on 18.1.20 by S. Cristoduolides and presumably a Baltic.
Looks like a 3cy but the age might not so easy? Pic are not the best but it looks like that the primaries are of a different generation, my take would be that the inners are 3 gen and the middle, or even the rest might be 2 gen, inspite of the mirror on p10. What's your take Mars?

Hi Jan,

Hard to tell the exact generation and timing of replacement when feathers are in such bad condition. In Lesser Black-backeds the primaries are sometimes difficult to age, but in this bird the secondaries are obviously adult-like and the wear in secondaries is about the same as it is in the primaries, so I assume the timing for moult must have been the same more or less. Therefore the primaries may well be 3rd gen, which would explain the obvious mirror in P10?

I remember photographing his sister (would be 20CY this year, but an almost exact replica!):
