[cobirds] Gulls/Fort Collins

Hello everyone, I've been seeing a type of gull fly over SE Fort Collins for a few nights in a row now. They're heading south, and seem to be eating insects or something higher up (can't get a good look at them). Does anyone know what they are? I'm guessing they're migrating south somewhere?

Exciting day today on this calm sunny day in the San Luis valley. Spent some serious time with camera and scope working on gulls at Smith Reservoir and San Luis lake. It was worth the effort as I saw some species we don't see very often. A juvenile *Sabine's Gull* was easily seen walking on
