Unlike their unstreaked parents, newly-fledged Spizella sparrows are heavily streaked below. This Brewer's Sparrow was along Bakeoven Rd. in s. Wasco County, Oregon on 29 June 2013. In this plumage this species exhibits a face and breast patterns that are strikingly similar to those of an adult Vesper Sparrow (also common in this area), but it lacks a rusty shoulder patch and white outer tail feathers seen on that species. Also note the lack of central breast spot.
We found this adult Brewer's Sparrow, just the second for Washington County, Oregon, at Koll Wetlands on 5 July 2013.
Here's another shot of the Koll Wetlands Brewer's Sparrow.
Brewer's Sparrow taken by Dan Mitchell at Lost Dutchman State Park, Arizona on 3/26/13.
Prior to going to the Santa Rosas, we spent a day and a half birding at lower elevations in southeastern Oregon and northwestern Nevada, where we were encountering almost no Brewer's Sparrows. Upon reaching the lush brush fields above 6000' in the Santa Rosas, they were incredibly abundant. We had as many as ten singing males at some stops. This male was singing at about 7000', just south of the Hinkey Summit.
