Detalles de la observación

1st cycle,, big uniform buffy white gull, primaries same as body, pudgy and pot bellied, bicolored bill. initially thought GWGU X HERG because of the pink bill base, but some GWGU can have a bicolored bill by this age and everything in the plumage looks uniform so GWGU may be the best match,. Certainly heavy on the GWGU influence, most GWGU X HERG have notably darker primaries, even when bleached, but still bugged by very pink bill and HERG structure.
