The last three days have brought at least one, possibly several flocks of 75-100 Chipping Sparrows to my yard at the base of Mt. Sanitas in Boulder. Other new arrivals were 3 male Black-headed Grosbeaks, 1 male Lazuli Bunting, 2 Rock Wrens, 1 Western Wood-Pewee, 2 Pine Siskins, 3-5 Lesser Goldfinches, 1 American Goldfinch, and, this morning, 2 Cassin's Kingbirds.
This afternoon I biked out to Sale Lake [1 Northern Waterthrush, 2 Yellow Warblers, 1 Gray Catbird, 1 male MacGillivray's Warbler, a handful of YR (Audubon's) Warbler's], then to Mesa Reservoir and Left Hand Reservoir north of Boulder. The sparrow fallout noted by Ted Floyd was truly awesome. Flocks of hundreds of Chipping, Lark, Brewer's, and Vesper Sparrows seemed to cover just about the entire landscape. One such flock was moving north over and through a barbed wire fence continuously for several minutes, at rate of just over 100 per minute for an estimated total of 400-500 individuals. Also in the area: 1 Western Kingbird, 1 Say's Phoebe, 1 Mountain Bluebird, 1 Gray Catbird, 1 Bullock's Oriole, and 3 Green-tailed Towhees among the expected species. At Left Hand Reservoir there were 7 Spotted Sandpipers, 3 American Pipits, 1 Wilson's Phalarope, 3 Least Sandpipers, and a flock of 17 Lark Buntings. I hope to have photos of some of these and other recent interesting species uploaded to my galleries soon.
