Blue-gray Gnatcatcher

Polioptila caerulea - A common canopy species of moist forests, recognized by its blue back, eye ring, fly-catching habit, and the sideways twitching of its long tail. Its nest, which is coated with lichens, is easily found before leaves emerge. Its high nasal calls are more frequent than its soft vireo-like song.
