  Gull - Wikipedia, the free encyclopedia
Apart from the kittiwakes, gulls are typically coastal or inland species, rarely venturing far out to sea.
Gulls — the larger species in particular, are resourceful and highly-intelligent birds, demonstrating complex methods of communication and a highly-developed social structure.

 Kelp Gull, Larus dominicus - probable hybrid   (Site not responding. Last check: 2007-11-05)
This dark-backed gull was present at Brownsville Landfill on March 16, 1999 (photos by Martin Reid), and is probably the bird reported on March 5 as a possible Kelp hybrid.
In my opinion the leg color was perfect for Kelp: a peculiar pale greenish-gray (and uniform throughout - unlike a minority of other large gulls that show areas of yellowish-gray and flesh on their legs).
Thus, I feel it is probably a Kelp x smithsonianus hybrid - and I arrive at this latter partner because this is the only known interspecific pairing of Kelp (and from fairly close by, in SW Louisiana).

Kelp should have yellow/green legs and a yellow iris with a red orbital ring.

Colonization of the Chandeleurs by Kelp Gulls may be related to the appearance of Kelp Gull on the Yucatan.

Adult California Gulls is easily separated from adult greenish-gray or gray-legged hybrids by the combination of dark brown iris, fl spot next to red gonys spot, and distinctive primary pattern (all white tip on primary #10, window on primary #9).

We examined microhabitat preferences and their adaptiveness for the kelp gull Larus dominicanus in one of its largest colonies in Patagonia.
Our study shows that some kelp gull breeding parameters are affected by nest-site habitat characteristics.
Vegetation effects and substrate characteristics were important variables in distinguishing random from nest sites and in explaining variation in breeding performance, showing that their habitat preferences are adaptive and allowing us to detect both the pattern and process in kelp gull habitat selection.

 Possible Kelp Gull at Dungeness   (Site not responding. Last check: 2007-11-05)
This unidentified gull was photographed by David Walker at Dungeness Point on 16 July 2001.
In size it was midway between Great Black-backed Gull and Lesser Black-backed Gull and exhibited a number of features indicating the bird may be a second year Kelp Gull or possibly a hybrid bird.
Also puzzling was the fact that this bird had relatively fresh flight feathers with no sign of moult at a time when all GBB Gulls and LBB Gulls are in the middle of their seasonal moult.

I suspect that almost all the gulls of the area are continuing to roost each night at Horseshoe Lake, with good viewing at dusk from CR28.

Most gull-watchers know that even in the field, the perceived shade of gray on a gull can change depending on the angle that the bird is standing.
Well in case you don't know it, scanning/preparing a photo image for display on a computer monitor introduces another enormous variable in the perceived shades of gray (and all color) - look at this revised sample that now includes an example of deceptive natural lighting.
It is possible for the person scanning/editing the image to selectively adjust any part of the image, but it is reasonable to assume that such manipulation is not done, so it is safe to assess relative shades of color between objects in the same image.

See also the Galveston TX Kelp, in direct comparison with American Herring Gulls (second pic): http://www.martinreid.com/kegup11.html Kelp looks large, but direct comparison with other large gulls is not so frequently available and its structure could be as much responsible of this feeling as its actual size.
Comparing measurements of Kelp in Hanzab (not all races I believe) with argenteus and argentatus in BWP also shows that Kelp on average is smaller.

 Band-tailed/Belcher's Gull
I propose that the well-established name of Band-tailed Gull be maintained, as it is a very good identifier of Larus belcheri.
However, since we are an AOU committee it would seem a bit odd if we were to come up with different English names, no? And Belcher's does have the advantage of being a mnemonic for the latin name..
So in this case we could use "band-tailed gulls" to refer to the two, and the patronyms Belcher's and Olrog's to refer to the individual components.
