Eastern Bluebird

The Eastern Bluebird, a small North American migratory thrush, is a delightful sight with its vivid blue plumage and rust-colored breast. The male's bright-blue breeding plumage is particularly striking, making it a favorite among birdwatchers.

Identification Tips

Males are resplendent with a bright blue head, back, and wings, contrasted by their brownish-red breast. Females are more subdued in color, with grayish tones on the head and back, and a touch of blue on the wings and tail. Their breast is more orange and lighter than that of the males.

Habitat

These birds favor open country with sparse ground cover and scattered trees. Habitats range from open pine savannas and mature woods to forest openings, and today they are often seen in pastures, agricultural fields, suburban parks, and golf courses.

Distribution

Eastern Bluebirds are found from the eastern Rockies across southern Canada to the Gulf states, and from southeastern Arizona down to Nicaragua. Their range has expanded westward, partly due to human activities such as fire suppression and tree planting.

Behaviour

Social yet territorial during breeding season, Eastern Bluebirds can gather in large flocks. They defend their feeding areas in winter and are known to assist in raising subsequent broods within a season.

Song & Calls

The male's call is a soft warble, sometimes sounding like "jeew" or "chir-wi," while its song is a melodious "chiti WEEW wewidoo."

Breeding

Eastern Bluebirds breed in the spring and summer, with females typically raising two broods each year. They nest in tree cavities, with the female constructing the nest and incubating the eggs. Both parents feed the insect-rich diet to their young, who leave the nest 15 to 20 days after hatching.

Diet and Feeding

Adults primarily consume insects and other invertebrates, supplemented by wild fruits and berries. They hunt by swooping down from a perch to catch prey on or near the ground.

Conservation status

Listed as Least Concern, Eastern Bluebirds have experienced population fluctuations over the years. Conservation efforts, including the establishment of bluebird trails and nest boxes, have helped stabilize and increase their numbers. However, competition with invasive species and habitat changes continue to pose challenges.

In culture

The Eastern Bluebird is a symbol of joy and the arrival of spring in American culture. It is the state bird of both Missouri and New York, reflecting its cherished status among bird enthusiasts.
