This page is for the Blue-gray Gnatcatcher (Polioptila caerulea). My first photographic evidence occurred on March 27, 2022 at the Fort Worth Nature Preserve, Fort Worth, TX. There were two of these very small birds flitting about very rapidly. It was difficult to get a picture as they rarely stayed still long enough to find the tiny bird and focus for a shot.
The photograph below is the other representative example of a Blue-gray Gnatcatcher that I have taken.
