Very abundant with an expanding range, The tree swallow is found in most all of North America with the . Summers find the tree swallow in all of northern US and most all of Alaska and Canada with the exception of the boreal tundra. Migration areas include everything else in North America. Winters find the tree swallow along the southeast Atlantic coast (North Carlina and below), all of the Gulf coast, south Texas and the Rio Grande valley. The central valley and the south coastal California have the tree swallow year round.

The tree swallow are normally seen in pairs or loose colonies, especially around still water. Large flock can be seen along coast in migration. Tree swallows nest in tree holes and birdhouses. When in flight, they alternately flap and then glide in circular motion, and rise when flapping. Tree swallow eat insects but when insects are unavailable, eat berries.

Glossy blue-green above, greener in fall and females are duller. Clear white below. Juvenile are brown above and may show some blue-green, but often have a dusty band across breast.

Arriving at the Warren Bridge campground, I set up my campsite, catch up on my journal writing and a little later, I go for a walk, see and photograph: two bald eagles, a osprey nest, a robin, and a tree swallow. I also take a few photos of the Warren Bridge. I next, return to the jammer and pound keys until about eight, when I stop, set outside with my camera and take photos of the sunglow and the full moon.

Most all of the swallows that I have photographed have been either barn or cliff swallows which have orange highlights on other parts of their body parts. Thus, because of the slight orange on the underside of this swallow, I struggled with identifying this bird. However, the back of this swallow is all dark green which would eliminate the swallow genus, Hirundo (barn, cave, cliff swallows) which helped me determine that this is of genus, Tachycineta.

Too, what helped most in the final identifying was remembering that it was nearly nine in the evening when the photo was taken and the sunglow from the setting sun was coloring everything a warm orange.
