觀察細節

Upon exiting my house, heard a buzzing call. Merlin identified both a Black-Throated Green Warbler and a Common Yellowthroat. Using my binoculars, spotted the Black-Throated Green Warbler in the upper eighth of the tree opposite my house. Black and white warbler with a yellow face and black throat and yellow smudge on the lower side underneath wing. Bird was moving ,seemingly feeding, but stopping to sing. Uncertain what it was feeding on, but there was a bloom of small flying insects visible above the tree.
