Habitat: 

A thin strip of scrub, about 20-30 yards deep and ½ mile long running alongside a gravel road. The strip is thickly vegetated with short (10-15 feet) holly, oak, and privet trees and Baccharis shrubs among others. 

 

Behavior of bird: 

In response to an owl tape, a large flock of kinglets, Orange-crowned Warblers, gnatcatchers, White-throated Sparrows and Myrtle Warblers gathered in a think clump of trees near my vehicle. Through the branches, I noticed the movement of a bird working along the rear edge of the clump rather than coming out in the open, behavior typical of Bell’s. I saw a bit of color through an opening that seemed good for BEVI or WEVI, so I played a BEVI call. The bird worked into the open, and I took some photos.
