Habitat Comparison
Common Myna
Urban areas, farmland, and open woodland. Closely associated with humans and one of the most successful avian urban colonizers.
Eastern Bluebird
Open woodland, farmland edges, orchards, and parks with scattered trees and open ground. Readily uses nest boxes.
Song & Call Comparison
Common Myna
A noisy, cackling chatter and melodious whistling mixed together. An accomplished mimic of other birds and sounds. Gives repeated 'mee-ow' and harsh 'quarr' alarm calls.
Eastern Bluebird
A rich, melodious warbled 'chur-wi, tur-a-lee' song. Both sexes sing. Call is a soft, musical 'turee'. Song is gentle and flute-like, suggesting a small thrush. Given from exposed perch.

About These Birds
Common Myna
The common myna has been named one of the world's 100 worst invasive species by the IUCN. Originally from South Asia, it has been introduced to tropical regions worldwide where it outcompetes native birds for nest cavities. Despite its invasive status, the myna is an intelligent and charismatic bird capable of mimicking human speech.
Eastern Bluebird
The eastern bluebird is a beloved symbol of happiness in North America. Once declining due to habitat loss and competition from introduced species, populations recovered dramatically thanks to a massive citizen science nest box campaign. These gentle thrushes form loose winter flocks and huddle together in nest boxes during cold snaps.
