It’s springtime and love is in the air. Two tree swallows (Tachycineta bicolor) seemed intent on getting to know each other better, but kept getting buzzed by a third swallow. A couple of times, one of the swallows, which I suspect was the male, took off and chased away the potential rival.

It must be tough being a bird.
Interloper! Tree Swallows sometimes have helpers at the nest to help defend it, but it doesn’t sound like that was the case here, if it involved chasing. Nice action shots, Mike!
