The Eastern Bluebird, Sialia sialis is our most colorful thrush. Reaching 6 to 7 inches in length these are fairly common permanent residents in the region. Simple nest of grass or pine needles are built in the bottoms of natural cavities or nest boxes, generally by the female.

In the mountains, nesting begins in March when 4 - 5 pale blue eggs (rarely white) are incubated by the female for 12 - 13 days. The male helps feed the young which remain in the nest for 15 - 18 days. Up to 3 broods are raised in a year. Birds of the year stay with the parents and may help feed the young of subsequent broods.

This species was seriously threatened by a lack of nesting sites, a problem exacerbated by the introduction of Purple Finches, a western species. There has been good success with preservation efforts, education and a growing appreciation of these beautiful birds.

The brilliant blue back, and orange-red breast of the breeding male are a delightful sight in spring. Typical thrushes, these are insectivorous but do consume berries and fruits in season.
