Open the appBirdsong and calls are often the easiest way to identify the Eastern Bluebird, especially when the bird is hidden in dense foliage. Below is what to listen for.
Song
A soft, warbling, gurgling song, often described as 'chur-lee, chur-lee' or 'tru-al-ly, tru-al-ly'. It's a pleasant, mellow sound, not particularly loud.
Calls
Common calls include a soft 'tu-a-wee' or 'chur' call, often given when disturbed or communicating with a mate. They also have a sharp, alarm call, 'chatter' or 'chur-chur-chur', when predators are nearby.
When they vocalize
Most vocal during the breeding season (spring and early summer), but calls can be heard year-round, especially when foraging or interacting with other bluebirds.
