Tree swallows are back..

The other day I cut the grass at our other property. I notice that there is a pair of tree swallows in the birdhouse that is on the old clothesline pole. They seem not to be bothered too much by my cutting the grass. A pair seems to nest there every year for several years now.

There are a few tree swallows around but barn swallows seem not too common anymore. However there are oodles of purple martins. Many people have special birdhouses for them.
