The 35 cent stamp, identified by its bright blue upper parts and rusty red breast, this male bluebird is perching on a Bermuda cedar  [Juniperus bermudiana] branch. The bluebird is 7 inches long. It feeds on earthworms, cut worms and caterpillars and also berries. Once it nested in cedar trees but now it almost always relies on nesting boxes for breeding.

The 85 cent stamp is represented by a female bluebird lying in its nest of dried grasses inside a nesting box. The female is solely responsible for building the nest and for incubating the eggs. It lays 4 or 5 pale blue eggs between March and August. They take 13 to 15 days to hatch.

The $1.10 stamp is a male bluebird may be encouraging a female to build a nest in the box. Every year the Bermuda Audubon Society holds a workshop on building bluebird boxes to the correct specifications. The boxes are usually made with spruce or pine shelving. The entrance hole is 1½ inches wide, effectively keeping out Starlings. Boxes should be regularly monitored, however, to keep out sparrows.

The $1.25 stamp displays the differences between the male and female bluebird.The female on top of the box is much duller in colour. In contrast, the male is more vibrantly blue. Here it is indulging in display behaviour to entice the female into using the box.
