Hybrid pair CG × LBBG in Belarus

Post by Dmitry Goncharov » Sat Feb 23, 2013 4:57 pm

Hybrid breeding pair (Caspian Gull × Lesser Black-backed Gull) with nestling in a mixed colony (Gatovo, 28-06-2012):
1 - male CG, 2 - female LBBG, 3 – hybrid nestling.
The first registration of nesting of Lesser Black-backed Gull for Belarus was in 2012.
Subspecies status of this LBBG is not yet clear.
Dmitry.

could you follow the nestlings's growth - did it survive? female looks more like an intermedius to me than a heuglini, but that's just a very subjective view.

Looks surely like an intermedius. We have single Darkbacked gulls in the inland of East Germany, they breed with everywhem equal come from.

Dear colleagues,
I will be grateful for your opinion: is it L.fuscus intermedius?
Dmitry

my feeling is yes, intermedius. as most birds in germany and denmark guess. doesn't look heuglini like from amount of black in wingtip, head and bill shape. do they breed now?

all the best and nice that you finally caught it!
