Blue-gray gnatcatcher
The Blue-gray Gnatcatcher is another very small songbirds. Adult males are blue-gray on their uppers with a white belly, have a thin dark bill, and a long black tail edged in white. In summer they also don a black “unibrow”. Females are less blue, while juveniles are greenish-gray. Both sexes have a white eye ring. Interestingly, gnats do not make up much of the Blue-gray Gnatcatcher’s diet, but they will eat them along with many other insects.
Good luck getting a good look at these birds. They aren’t very common here in the canyon and when they do show up, they rarely slow down, flitting from brach to branch and tree to tree like they have a nervous tick.
