Eastern Bluebird
Sialia sialis
A brilliant blue cavity-nesting songbird found in open Florida landscapes with scattered trees and low grass.
Eastern Bluebirds favor open pine country, pastures, golf courses, parks, and spacious residential landscapes. Males show vivid blue upperparts and a rusty orange breast, while females wear softer blue-gray tones.
They need open ground for hunting and nearby cavities for nesting. Properly placed nest boxes, short untreated turf, native berry plants, and reduced insecticide use make a property more useful to bluebirds.
