I went around Broomfield this morning, and got some migrants including Snowy Egret, (Plaster Reservoir) American Avocet, (Quail Creek Pond) and Western Grebe (McKay Lake). Also had Brown-headed Cowbirds and Swainson's Hawks at multiple locations. Also, last week, I had Franklin's Gulls at Matthew T Glasser Reservoir, although this morning was pretty quiet there, and several Yellow-rumped Warblers at a couple different ponds and creeks.
Just a head's up. A Long-billed Curlew flew over my house at dawn this morning, heading north. I could not re-find it this morning in Broomfield, but It might be worth to check some East Boulder reservoirs for it.
