[SBB] Brewer's Sparrow continues

About 9 this morning I had the BREWER'S SPARROW on the west bank of the creek (Guadalupe River at this point?), east of the road between the Water District Pond and the creek 200 -250 feet north of where the access road makes a left turn toward the north. The BRSP was actively feeding a couple feet away from the base of a bush on the edge of the water (a beige bench is perhaps 20 feet south of the bush). The bush itself was full of BUSHTITS with a few spilling out onto the ground near the BRSP. Something then spooked the Bushtits and they flew, in a stream, across the creek. At that point the BRSP went into the base of the bush and disappeared. Unfortunately, after that my attention was divided as I wanted to make sure that BRSP hadn't flown across with the Bushtits (don't know why it would). Some motion was still detected in the bush after that but the bird was not seen again. Later Mike Mammoser assured me that this was the same bush near which the BRSP had been seen on Sunday morning (I had assumed it was seen further upstream). Lots of YELLOW WARBLERS and calling NUTMEG MANNIKINS just downstream of where the BRSP was seen.
