Comments:
Here before sun-up today. Cool, 46 degrees at start, 63 by end. Walked 1.8 miles and drove another two, approximately. Highlights were a cooperative American Mink, a first-year male American Redstart, and 95 Swainson's Hawks. There definitely seemed to be a southwesterly movement of flickers, jays, and maybe other birds. Most of our usual migrant species: vireos, orioles, grosbeaks, buntings, Empids, etc. were absent.

Fifteen had been observed flying out of a night roost in the tall cottonwoods by the Sacramento River, but when I went farther down the road, I was able to count exactly 95 Swainson's Hawks on the ground on a huge, recently plowed fiend on the south side of the road at the gray mailbox with "93" on it.

American Redstart

A first-year male was found in the oaks by the former railroad crossing 0.5 miles s.w. of S. River Rd. Starting to get dark lores and a few black feathers on the cheek and upper breast. Orange sides. The bird was very active, high up, and mostly in poor light, so was difficult to photograph.
