American Tree Sparrow

American Tree Sparrow - Spizella arborea

The Tree Swallow is one of the first swallows to arrive in spring as the bird migrated to the Arctic breeding grounds. Some nest at the northern edge of Alberta.  
These sparrows shake weed stems to cause the seeds to fall to the ground to facilitate feeding. The sparrows either jump against the stem or beat the stem with their wings during flight.
This Tree Sparrow managed to find sunflower seeds
below my feeders on a very snowy April 14, 2013.
This Tree Swallow was on the way south on October 12, 2012
