What was the SIZE of the Gray Hummingbird-like bird you saw in Pennsylvania?



Calliope Hummingbird: Very small hummingbird, metallic green upperparts and flanks, white underparts. Throat feathers are long, purple-red, appearing as streaks on a white background, whiskers when fluffed out, or dark, inverted V when folded. Direct and hovering flight with very rapid wing beats.
