Blue-Gray Gnatcatcher

Polioptila caerulea

The Blue-gray Gnatcatcher is the northernmost-occurring species of gnatcatcher, and the only one that migrates. They breed over much of the eastern USA north to the Great Lakes and New England, and in the southwestern USA and California.

Nest failure is common in these birds and they may attempt six or seven nests in a season, reusing old nest material. Usually two broods are raised successfully per season.
