觀察細節

Minimum, all in one flock in the pine forest and edge habitat at (42.6549315, -70.8474827). Mixed with goldfinches and bluebirds, but chipping frequently, and it sounded like at least five birds - probably more. Visually too, branches of the pine had several Pine Warblers in view at once before they would retreat deeper into the tree. Photos taken of several birds and audio recording of the flock chipping.
