TURDIDAE

Order Passeriformes    Family Turdidae

Thrushes are plump, soft-plumaged, small to medium-sized birds, inhabiting wooded areas. Most species are grey or brown in color, often with speckled underparts. Even if the adults do not have these speckles, the juveniles often will. They are insectivorous, but most species also eat worms, snails, and fruit. Thrushes build cup-shaped nests, sometimes lining them with mud. Except for the bluebirds, thrushes construct their nests on branches. The blues place their nests in cavities. Thrushes lay two to five eggs which are usually speckled, sometimes laying two or more clutches per year. Both parents help in raising the young. The songs of some species are considered to be among the most beautiful in the avian world.

Bluebirds


There are three species of bluebirds: the eastern, mountain, and western; all are in the Sialia genus. They are found in North America and south into Central America. They eat insects, worms, and fruit when insects are scare. Because of their vivid blue color, bluebirds are a favorite of people and their survival is enhanced by feeders and bird houses. Before this intervention, their population had been in decline due to the house sparrow and European startling, both of which are introduced species and compete for nesting spots. Also, the bird houses can be constructed to discourage predators such as snakes, cats, and raccoons. Bluebirds do not like the bird seeds that are commonly put in feeders. However, they can be attacted to platform feeders with grubs that sold by bird supply stores as mealworms. They also like raisons that have been soaked in water.
