He’s handsome. He’s friendly. He’s brave. He’s funny. He’s an entertainer. He’s an acrobat. And he helps protect me from biting insects. It’s the tree swallow (Tachycineta bicolor or TRES), a swallow that breeds over most of North America… except the Southeast. Tidewater Virginia is in the ‘maybe’ zone and I’d never experienced this species of swallow.
Although their summer diet is insects, the male tree swallow, with his beautiful iridescent green-blue back, would land atop the bird feeder pole, looking left and right up and down at the seed-eating birds, never bothering them but looked simply curious.
From the break of day to the last rays of light at night, the pair of tree swallows that took up residence in one of our new bluebird houses commanded the skies in search of insects. Their aerial acrobatics and sweet warbles to each other made me think of the lyrics from Captain and Tennille’s “Muskrat Love”:
And they whirled and they twirled and they tangoed
Singin’ and jingin’ the jango
Floatin’ like the heavens above….
It looks like muskrat love
Dipping and dancing, twirling and soaring, these agile little fellas coursed over fields and water at speeds of 25 MPH consuming insects… up to 2,000 insects each and feeding 6,000 to their offspring in the 45-day nesting period according to Dick Tuttle of the Ohio Bluebird Society.
Our tree swallows have raised their one batch of young that have recently fledged. I can see the entire family flying back and forth across the small pond across the field catching insects in the air. Since they were finished with their house, I opened it yesterday and this is what I found.
In reading more about tree swallows, I should have opened the bird box regularly to check on the chicks and evict any house sparrows that may have taken up residence. The house sparrow is a European invasive and a threat to the welfare of the swallows. To learn more about the tree swallow, click here.
