Those little birds.... they grow up and fly away, like the prior cache here has done multiple times. This one is a bit more out of the way, so hopely it won't fly off, too.
You may find Field Sparrows around here. It is a common sparrow of brushy pastures and old fields. It has an unstreaked chest, a gray face, and a pink bill. It has a simple, yet distinctive song of repeated clear whistled notes on one pitch that increase in rate until they make a trill. Think of a ping pong ball dropped on a table: the sound starts slow and gets faster.
There is plenty of parking off Windmill Road.
