Back of card caption:

Bluebird (Sialia sialis)
In the North, the simple warbled notes of Bluebirds are among the first sounds of spring. In the South, they can be heard year round. Bluebirds nest in cavities, in trees, old Woodpecker holes or bird boxes. Four or five pale blue eggs are laid. Boxes for them should be 5" x 5" x 8" deep, with a hole placed above center 1.5" in diameter, small enough to keep out the Starlings. The birdhouse should be put up on a pole about 5 or 6 feet from the ground, in a sunny open place. The Western Bluebird is very similar to the Eastern but has a chestnut patch in the center of its back.
