Not a good pic but there's 2 hummingbirds in close proximity. This is weird w/o a fight & seconds later they did. The 1 at upper L attacked the one at lower R flying into it with an audible THWACK, tiny body to tiny body. They then chased through the airspace of the yard, over here low (THWACK), over here high (THWACK), now back (THWACK), now around & around way high (THWACKITY-THWACK-THWACK), before 1 chased off the other to drink at the feeder, the objective of the struggle. #birdsofmastodon
