Tree Swallow Battle

Tree Swallows are interesting to watch and very, very fast birds. They move quickly, back and forth, up and down, swooping, swerving, and diving. To catch them in a picture is sometimes quite the challenge....lol.  On one of our outings, we happened to catch 2 tree swallows flying around and then it began.....for a few seconds.....a battle over something. One of the birds was very upset at the other one :)  I find wildlife behaviour very interesting.
