Top Photo: Two young tree swallows wait at entrance hole to nest box.

The nest box pictured here was installed in the wetlands during the first half of March.

Though the nest box was intended for either wood ducks or hooded mergansers, by the first week of April tree swallows were actively building a nest in the spacious structure.

I’m happy to say that tree swallows have now fledged from the nest as of Saturday, the fourth day of June.

Over the course of the day, I was able to see six swallows in view at a time. Eliminating the two adults, that makes at least four fledglings.
