Aerodynamic and graceful, a tree swallow is most often seen in the sky as it gleans insects on the wing. It is about the size of a chickadee, and is an iridescent blue above and white below. Tree swallows are often seen in small flocks foraging over ponds or fields, chittering back and forth.

Here are five photos of tree swallows from past years’ photo contests. If you have a great shot of your own, we’d love to see it! Enter today at massaudubon.org/picturethis.

We love all of the categories in the Picture This: Your Great Outdoors photo contest—landscapes, wildlife, plants & fungi—but it’s the People in Nature category that gets us every time.

Here at Mass Audubon, our mission is to protect the nature of Massachusetts both for wildlife and for people. So it’s beautiful scenes of people getting outdoors and enjoying nature that bring us the most joy.
