Bluebird Facts

  • Bluebird nests are light and delicate–consisting of grasses, hair fibers, feathers and needles.
  • The nests are built with a small, cap-like shape near the center to help hold eggs in place.
  • Female Bluebirds lay four or five eggs at a time and incubate them for around two weeks.

  • Bluebirds have extremely thin skin. Pesticides are dangerous to them as a result.

  • Males from a first brood will often come back to help feed the second brood.
  • Swallows can be dangerous to Bluebirds, but they sometimes help feed the young Bluebirds too! They will help the small birds grow and then take over the nesting box once the Bluebirds have fledged.
  • Bluebirds are fruit and insect foragers, but they can be trained to use a seed feeder if it is kept near their birdhouse.
