These little birds are highly social creatures. Migrating flocks can number in the hundreds of thousands! They make their nests in dead trees (such as this). They lay 4-7 eggs which start off as pale pink, then turn pure white within 4 days. The eggs have an incubation period of 11-20 days and a nesting period of 15-25 days.

Tree swallows are built to be nimble! Their aerodynamic head, wings and tail feathers allow them to turn on a dime. They can even barely skim the surface of a lake or stream while submerging just their beak to get a quick drink on the go! I combined a few of my favourite Tree Swallow aerobatic special moves into this single photo. I hope you enjoyed this short post on the amazing and adorable Tree Swallow!
