Bluebirds build their nests in a natural tree cavity or abandoned woodpecker hole 3 to 20 feet above the ground. The nest is made from grass, plant stems, pine needles, hair and feathers. Breeding pairs will eagerly accept a bluebird bird house as a nesting site. The clutch will contain 3 to 6 eggs and incubation takes 16 to 21 days.

A Few Things You Probably Didn't Know:

  • The Eastern Bluebird suffered large population declines until the 1970's. This was due in part to loss of cavity nesting sites. The erection of nest boxes across the country has led to increased bluebird populations in many areas.
  • The male will attract a female by bringing nest materials to the cavity hole. He then goes in and out and waves his wings while perched above the hole. That is pretty much his contribution to nest building; only the female Eastern Bluebird builds the nest and incubates the eggs.
  • Bluebirds have more than one successful brood each year. Young birds from early nests usually leave their parents in summer, but young from later nests frequently stay with their parents over the winter.
