About A Bird - Tree Swallow (Tachycineta Bicolor)

Friday has finally arrived but unfortunately so has the rain.  If you find yourself caught indoors and are looking for something to do, I hope this post helps get you through. ;-)  This week we have chosen the Tree Swallow - we love they way the look, especially on camera and we love, love, love to watch them in flight.  Here we go...

  • a small songbird from the Swallow family.
  • are 5" long and weigh approximately 20 grams.
  • have a very small bill and their tail is slightly forked.
  • an adult has iridescent blue/green colouring on its head, back and wings with a white throat and underside.  
  • are extremely social birds.  It has been reported that during non-breeding times groups of over a hundred thousand birds can congregate...now that's a party!! ;-)
  • breed in North America and winter in Mexico, Central America and the Caribbean.

  • are unable to build a cavity to nest in.  Instead, they will often use an abandoned cavity or a nest box, like those of Bluebirds.
  • a typical nest will consist of grass and twigs lined with feathers, most often from waterfowl which helps in keeping the nest warm and dry.
  • female will lay 4-7 white eggs and will incubate them by herself.
  • the eggs hatch in 14 days.
  • the young a born altricial which means they are in incapable of moving on their own.  In order to survive they must be given nourishment.  
  • normally fledge after 16-24 days.

  • adults will often dive bomb intruders in an effort to drive them away.
  • are very competitive when it comes to nest boxes and will often fight an Eastern Bluebird for real estate.
  • a mating pair will only produce one brood per year unless an early attempt is not successful.
  • eat mostly insects which they catch on the wing.  They will sometimes also eat fruit.
  • are incredibly gifted in flight - precise, graceful and fast.
  • are rarely seen on the ground because their wings are too long to take flight while grounded.
  • in some parts of the world they're considered a delicacy.  A while back Nate and I watched Anthony Bourdain munch one down on his show, ew. :-(
  • there's an old saying which goes "Low flies the swallow, rain will follow.  When the Swallows fly high, the weather will be dry."  This is not just an old wives tale, it's actually backed by science.  Rain is associated with low air pressure which forces the flying insects to remain low.  Since Tree Swallows eat insects in flight they are also forced to remain low.

 

While online yesterday I ran across a page of Aesop's Fables - this one caught my eye so I thought I'd add it to the post.  Hope you all have a great weekend. :-)
