The Eastern Bluebird (Sialia sialis) is a small thrush found in open woodlands, farmlands, and orchards. It is the state bird of Missouri[and New York.
This species measures 16–21 cm (6.3–8.3 in) long, spans 25–32 cm (9.8–12.6 in) across the wings, and weighs 27–34 g (0.95–1.20 oz). Eastern Bluebirds are found east of the Rockies, southern Canada to the Gulf States, and southeastern Arizona to Nicaragua. The increase in trees throughout the Great Plains during the past century due to fire suppression and tree planting facilitated the western range expansion of the eastern bluebird as well as range expansions of many other species of birds.
The bright-blue breeding plumage of the male, easily observed on a wire or open perch, makes this species a favorite of birders. The male’s call sometimes includes soft warbles of ‘jeew’ or ‘chir-wi’ or the melodious song ‘chiti WEEW wewidoo’. [Wikipedia]
Most of the country drives during an eastern North American summer will turn up a few Eastern Bluebirds sitting on telephone wires or perched atop a nest box, calling out in a short, wavering voice or abruptly dropping to the ground after an insect. Marvelous birds to capture in your binoculars, male Eastern Bluebirds are a brilliant royal blue on the back and head, and warm red-brown on the breast. Blue tinges in the wings and tail give the grayer females an elegant look. [All About Birds]
Eastern Bluebird Facts [All About Birds]
- Eastern Bluebirds eat mostly insects, wild fruit, and berries. Occasionally, Eastern Bluebirds have also been observed capturing and eating larger prey items such as shrews, salamanders, snakes, lizards and tree frogs.
- The male Eastern Bluebird displays at his nest cavity to attract a female. He brings nest material to the hole, goes in and out, and waves his wings while perched above it. That is pretty much his contribution to nest building; only the female Eastern Bluebird builds the nest and incubates the eggs.
- Eastern Bluebirds typically have more than one successful brood per year. Young produced in early nests usually leave their parents in summer, but young from later nests frequently stay with their parents over the winter.
- The oldest recorded Eastern Bluebird was at least 10 years, 6 months old. It had been banded in New York in May 1989 and was found dead in South Carolina November 1999.
