Swallows Passing Through

Dozens of swallows were giving an aerial show over my property today. I think they are tree swallows...they don't stay still long enough for a true ID. Here's a short video of their acrobatics. Collectively they are known as a "stand" of swallows. Spring is definitely in the air! The bluebirds began bringing nesting materials to the nest box.
