cachinnans yellow PHDK:pure or not?

Post by alfosse » Fri Sep 19, 2014 5:58 pm

These pictures, taken on 19 Nov 2011 somewhere in Normandy (France), have been sent to me by a friend (not taken by him).
He asks for the true identity of that bird (ringed as a "Larus cachinnans kolonia"): pure cachinnnans or hybrid?

salut alain,

personally i see nothing to suggest argentatus (or any other taxon's) involvement. bill a bit stubby but certainly within cachi variation!

best,

lou

Thank you Lou.
I do agree: my friend was puzzled by the shortish bill and legs, for the latter the fluffy belly feathers are probably responsible of the "shortness" of the legs.

Hi all,
FYI, PHDK was approved as a Caspian Gull by Normand CHR (regional Rare Birds Committee) in its 2013 report, "despite its rather stubby [court et fort] bill".
Tony Le Huu Nghia found and followed this bird during a week in Dives-sur-Mer (Calvados).
Regards,
Emmanuel
