Tree Swallows

Tree Swallows

There are birds that serve humans well and one of those species is the tree swallow. As an aerial insectivore, these small, five-inch birds help to eliminate mosquitoes as well as insects that do extensive crop damage. Tree swallows are very pretty blue birds that breed mostly in North America but which migrate during the winter as far south as the northern part of South America.  

Tree Swallows ~ Videos: Here is a fascinating 8-minute video featuring a man who protects his tree swallows’ home from an aggressive sparrow. Warning: the sparrow dies, but the man presents his arguments for this decision very well. Here’s a fun 3-minute video of tree swallows gathering at the top of a tree then, dispersing in a sudden movement.

  • Basic information, quote: The tree swallow (Tachycineta bicolor) is a migratory bird of the family Hirundinidae. Found in the Americas, the tree swallow was first described in 1807 by French ornithologist Louis Vieillot as Hirundo bicolor. It has since been moved to its current genus, Tachycineta, within which its phylogenetic placement is debated. The tree swallow has glossy blue-green upperparts, with the exception of the blackish wings and tail, and white underparts. The bill is black, the eyes dark brown, and the legs and feet pale brown.

  • The female tree swallow is usually duller than the male. A young female tends to have brown upper parts with some blue feathers.
  • Tree swallows breed in the U.S. and Canada.
  • As migratory birds, tree swallows winter along southern US coasts, in the West Indies, along the Gulf Coast to Panama and the northwestern coast of South America.
  • Tree swallows will nest as isolated pairs or in loose groups.
  • Tree swallows will nest in both artificial and natural cavities.
  • Tree swallow pairs tend to be monogamous.
  • A typical clutch is four to seven eggs but can be anywhere from two to eight.
  • Incubation of eggs is from 14 to 15 days.
  • Chicks fledge 18 to 22 days after hatching.
  • Though tree swallows mostly eat insects and are considered an ‘aerial insectivore’, they also feed on molluscs, spiders and fruit.
  • Tree swallows are usually between about 12 and 14 cm long (4.7 and 5.5 in).
  • The tree swallow’s song is three long and descending notes ending with a warble.
