This bird is VERY similar to (if not the SAME as!) an odd gull observed in Saskatchewan in October of this year. I think the consensus was a melanistic Ring-billed gull with partial albinism (i.e., a Ring-billed gull with serious plumage issues!). Jesse Ellis started a thread on the ID-frontiers list about that bird on Oct 29, 2012.
Photos of that bird (of it's right side): http://www.birdforum.net/showthread.php?p=2576343

VERY COOL find if it's the same bird! Well worth a write-up in the JCFO, especially if it sticks around for more photos that can help support a definitive ID.
Best,

I guess the smaller gull with a black bill with a yellow tip at Pueblo Reservoir today, isn't a Sabine's Gull, though it is unknown what it might be. If you were hoping to see a Sabine's Gull, I guess this bird isn't one. Gulls are really annoying, just like swans and "winter" type wrens.
Two of my photos of the "unknown funny gull" can be seen at http://www.flickr.com/photos/brandonsbirdphotos/ Bill Maynard has better photos that have also been looked at.
If I have time tomorrow, I'll try look for this bird again, and hope for some better photos, or perhaps a photo of it flying. Not sure this bird will be figured out, unless it is seen again.Brandon PercivalPueblo West, CO--
