Tree Swallow
Tachycineta bicolor
A dazzling iridescent blue-green swallow that swoops and glides effortlessly over water and open fields. One of the most acrobatic fliers you'll see at ABNC.
Field Note
Tree Swallows are one of the few songbirds that regularly eat berries in winter — especially waxy bayberries — which lets them survive cold snaps that ground insect-only eaters.
Where to Spot It at ABNC
Flying over the wetland and open grassland, especially in the morning. They also nest in boxes — check any nest boxes around the site in spring.
Why It Matters
Tree Swallows eat enormous numbers of flying insects, including mosquitoes. They readily use nest boxes, making them a great species for community conservation programs.
Good to Know
Tree Swallows are nature's acrobats — they twist and swoop through the air so fast it makes your head spin! Their backs look like shiny blue-green metal in the sun.
