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. 

FunFacts about Tree Swallows: (Source)

  • 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.
  • Tree swallows are considered ‘model organisms’.

  1. Tree swallows are such pretty birds! The blue is very eye-catching. I like the fact that they help against mosquitoes!

  2. I enjoyed watching the videos. Love the beautiful pictures of the tree swallows. I have always loved the blue color of them.

  3. Anywhere from 2 to 8 in a clutch! Those are some busy parents. The iridescent blue is eye catching.

  4. When the sun hits the blue on these birds, it makes their feathers shine. So pretty! Love the picture of the two babies with their mouths open ready for some food!

  5. I’ve got lots of tree swallows on my property. Probably b/c of the pond which mean we have an abundance of mosquitoes each year. I’ve seen lots of females but only a few males. I love their bright blue color. I love the photo of two grumpy looking ones

  6. I don’t believe I’ve ever seen these charming birds before. I love the picture with the babies peering out at you!

  7. Very pretty. I don’t recall seeing them around here. We have swallows but not with that beautiful blue. NE Ohio.

  8. To my knowledge, they are not right around here. I like the photo of the two birds with the stern/sour face. Adorable. I live just north of Tampa FL.

  9. I live in NC, but sadly I haven’t seen that pretty Swallow.
    In fact I don’t think I’ve ever seen any type of Swallow here.

  10. I really can’t decide on a favorite pic. The fat little bird is just too cute. And the 2 looking out at you with that grumpy/stern “leave me alone” look is to die for. The picture with the two with their mouths open, singing reminds me of two women I know who sing in the choir. You could write a book and use the pictures to create a town of people and their characters.

  11. Oh my goodness I have never seen such beautiful birds before love all the pictures you made my day ! Thanks

  12. The sapphire coloring is sleek and shiny it’s almost metallic!! I have yet to spot one in person tho..

  13. We have tree swallows but I have never seen them with that color. Loved the picture with the two birds facing each other that looked like they were kissing.

  14. I like the 9th and the 12th pictures. I don’t know if i have seen one in the wild or not. I will have to be more observant.

  15. The blue feathers on these are quite beautiful. I have only seen this type of bird with brown feathers that help them just blend in with nature. Really liked the part about them killing mosquitoes..

  16. They are so pretty. I saw them in action once. I was at a lake house at dusk a few summers ago and was fascinated by these little swooping birds. They were feeding on the mosquitoes. (Our state bird).
