The folks in the Riverwalk Bird Club don't just watch birds. The group includes some excellent photographers.

Nooga.com Outdoors is happy to share their great photos by featuring a Bird of the Week.

This week, we feature an eastern bluebird by Harold Sharp, taken at the Greenway Farm in Hixson.

Interesting facts
—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.

—Eastern bluebirds occur across eastern North America and south as far as Nicaragua. Birds that live farther north and west of the range tend to lay more eggs than eastern and southern 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 oldest recorded eastern bluebird was 10 years and 5 months old.
