Hi all,

I made a quick trip up to Summit County yesterday and found Dillon Reservoir to be exceptionally birdy. The Blue River Inlet (PUSA spot) was especially good, featuring a Lesser Black-backed Gull, a WESTERN GULL (presumably the Chaffee County bird that's now relocated), and several THICK-BILLED LONGSPURS and CHESTNUT-COLLARED LONGSPURS on the exposed lakebed. These appear to be the first longspur reports of any species from Summit County, but the habitat is certainly excellent right now.

Good birding,
