In Canada, they live as far north as Nova Scotia and Newfoundland in the east. Eastern bluebirds also can be found throughout Mexico and Central America.
- Migration: These birds migrate south for the winter and return north when spring arrives. Eastern bluebirds are small, native North American songbirds that typically spend their winters in Central America or South America before returning to their breeding grounds as the weather warms up in late March or early April.
- Habitat: They inhabit forests, meadows, parks, golf courses, grasslands, marshes, woodlands and farmland in rural areas throughout this region.
- Diet: The diet consists mostly of insects such as grasshoppers ants, spider and beetles, which they glean from tree branches or ground vegetation; however, bluebird will also eat small fruits and berries during fall migration.
- Global extent of occurrence: 14,800,000 km2. (5714311.9464 sq mi.).
- Global Population: est. 23,000,000 Individuals.
- Conservation Status: Listed as Least Concern (Population is increasing).
- Lifespan: In the Wild: 6 years of age. – In Captivity: 10 years of age.
- Breeding Period: April through July.
- Incubation Duration: 11-19 days.
- Chicks Fledge: 16-25 days.
- Clutch Size: 3-7 eggs.
- Number of Broods: 1-3 brood per year.

- Nesting Habits: They build nests in tree cavities or bird boxes, choosing sites with good visibility, low on tree trunks or on fence posts. They may also take over abandoned nests of other birds if they feel threatened. Female Eastern Bluebirds lay between three and seven eggs, which can be greenish white to sky blue with dark spots on them. The female incubates the eggs for about two weeks before hatching. The male helps feed the hatchlings, as well as bringing food to his mate while she sits on the nest. Eastern bluebirds reach sexual maturity at one year.
Fun Facts About Eastern Bluebirds
- The Eastern Bluebird was first described in 1758 by Carl Linnaeus, a Swedish naturalist and zoologist.

- The Eastern Bluebird was on the verge of becoming extinct in the early 1900s due to massive loss in habitat and competition with other birds such as House Sparrows and European Starlings. Luckily, conservation efforts have increased their population, so they are no longer on the list of endangered species.
