It reminds me of kids at a park or beach, chasing each other is a seemingly random game, not of tag, just of chase. Well, after all, these birds are kids after all. I suspect that their “games” are not so much for fun as for strengthening little wings for the long migration just ahead, and testing out the idea of territory control. They seem to waste so much energy in the pursuit of each other I wonder how they ever store enough fat for the flight to Central America. All but the latest hatchlings do store enough fat for the trip, and those late arrivals try to tough it out on the gulf coast until spring. In cold winters they usually don’t make it.
Hopefully these youngsters are old enough to go south, really south, and will be back next year, swooping and buzzing around my windows once again. Bon Voyage guys. Watch you backs.
