Hey, all.

Swainson thrushes are migrating over Lafayette, eastern Boulder Co., right now in the fine mist. Lovely to hear their little whistles in the darkness. Not a massive East Coast–style flight, but one or two per minute. Also a resident common nighthawk or two.

A few other odds and ends:

Yesterday, Mon., June 2, at Murphy's Pasture & environs, Pawnee National Grassland, Weld Co., Hannah Floyd and I found many grasshopper, Cassin, & Brewer sparrows. Great encounters, too, with a greater short-horned lizard and a prairie rattlesnake. We missed the funnel cloud directly over Briggsdale; we left too early.

And back on Sun., June 1, along the Fowler Trail & environs above Eldorado Springs, Boulder Co., Kieran Schnitzspahn, Hannah Floyd, Isabelle Busch, Owen Robertson, Archer Silverman, and I found at least six ovenbirds, along with the usual slug of Hammond flycatchers, plumbeous vireos, Virginia & MacGillivray warblers, and lazigo buntings. Also, a peregrine falcon, likely a resident.
