CLOSED: Gull IDs

Are the two big ones in this pic Ring-billed gulls? The others are laughing gulls right?

Ringbilled and laughing?

The brown one just looks bigger b/c it's brown right? Still ring-billed?

Same question -- oh and what are the ducks in the 1st pic?

#1 - pair of American Herring Gulls with Laughers; ducks probably Gadwall, but not definite.

#2 & 3 - two immature American Herring Gulls (brown is 1st winter, grey-brown is 2nd winter), plus two Ring-billed (silvery grey birds, just below, and below left, of the AHGs), with Laughers.

#4 - 9 adult and 2 immature AHGs (large), 2 Ring-billed (small pale grey), 5 Laughers (small dark grey); also 2 Double-crested Cormorants and 3 Brown Pelicans.
