Eastern Bluebird - Sialia sialisA favorite summer visitor for many, the Eastern Bluebird is more common in the eastern part of the state.  They historically have used old woodpecker holes and other cavities in trees for nesting.  However, they will readily nest in man-made bluebird boxes, and have greatly benefited from the increased placement of these boxes, especially as European Starlings have become aggressive competitors for natural tree cavities for nesting.

Habitat: Eastern Bluebirds can be found in a variety of open and semi-open habitats.  They prefer open country interspersed with trees for nesting. 

Diet: Mostly insects and berries. 

Behavior: Often feeds by observing from a relatively low perch and flying down to pluck insects from the ground or foliage, often hovering instead of landing while taking the food item.  They will also sometimes fly out and catch insects in mid-air.  Breeding pairs may perch next to and preen each other.

Nesting: Late April through July

Song: Eastern Bluebird Call

Migration: Winters in the southeastern United States and Mexico, although small numbers may winter in the state in selected spots.  Summers throughout most of the eastern half of the United States and southeastern Canada.

Similar Species: Western Bluebird

Bird Feeders: Will sometimes attend feeders for mealworms (yes, you can buy mealworms to feed to bluebirds!)

Conservation Status: Showed sharp decline previously due to competition for nesting sites with non-native species (European Starling, House Sparrow).  Has been recovering, thanks in large part to the large numbers of nest boxes erected for their benefit.  The IUCN currently lists Eastern Bluebirds as a species of "Least Concern".
