Tree swallow on a wire, balancing in the wind, yesterday on Mount Agamenticus.
I was looking for migrating hawks and I found swallows instead, dozens of them.
Handsome aerialists with deep-blue iridescent backs and clean white fronts, Tree Swallows are a familiar sight in summer fields and wetlands across northern North America. They chase after flying insects with acrobatic twists and turns, their steely blue-green feathers flashing in the sunlight.
I do love the handsome aerialists.
Swallows and martins are the family Hirundinidae.
Swallows have adapted to hunting insects on the wing by developing a slender, streamlined body and long pointed wings, which allow great maneuverability and endurance, as well as frequent periods of gliding. Their body shape allows for very efficient flight, which costs 50–75% less for swallows than equivalent passerines of the same size.
It’s surely summer, for there’s a swallow:
Come one swallow, his mate will follow,
The bird race quicken and wheel and thicken.
– Christina Rossetti, A Bird Song
