low elevation Pinyon Jays - Boulder 9/8

[Scott E. Severs]

Seems that there was a regional pulse of Pinyon Jay migration today as a flock of 28 birds flew over Walden/Sawhill Ponds. Other notables includes a Chestnut-collared Longspur (flyover noted by its flight calls), and an American Bittern. Several of Ted's Warbling Vireos were around too.

Yes, and one of them was singing and audio-recorded yesterday, Friday, Sept. 7th. It was an Eastern, near the southwest corner of Cottonwood Marsh. Makes sense: Eastern Warbling-Vireos are supposed to stick around on the breeding grounds to molt, whereas Westerns are supposed to bail and molt elsewhere. Another warbling-vireo at Walden yesterday was strikingly yellow--but nevertheless a warbling-vireo.

Scott's Townsend's Warblers were still down by Boulder Creek, and the place was seriously infested with Wilson's Warblers.
