Blue-gray Gnatcatcher (Polioptila caerulea)
Tiny and lively, Blue-gray Gnatcatchers are constantly on the move! This is very likely a female in search of spiders and insects.
These gnatcatchers are expanding their breeding range northward so I have been lucky enough to see one or two in each of the past three years.
