The Brown Thrasher (Toxostoma rufum), sometimes erroneously called the Brown Thrush,[2] is a bird in the Mimidae family, a group that also includes the New World catbirds and mockingbirds.

Contents

Description

The Brown Thrasher is brown or reddish-brown above, with a white breast and throat streaked with brown, and two white bars on each wing. It has a long tail, and its beak is also relatively large and somewhat curved. Adults average about 29 centimetres (11 in) in length.

In fact, it is more likely to be heard than seen, not only because of the rattling of leaves, but also because of its call, a sharp lip-smacking type sound.

Habitat and range

It is found in thickets and dense brush, often searching for food in dry leaves on the ground. Its breeding range includes the United States and Canada east of the Rocky Mountains. It is a partial migrant, with northern birds wintering in the southern USA, where it occurs throughout the year. There is a single British record of this unlikely transatlantic vagrant.

Behavior

Feeding

This bird is omnivorous, eating insects, berries, nuts and seeds, as well as earthworms, snails and sometimes lizards.

Breeding

The female lays 3 to 5 eggs in a twiggy nest lined with grass. The nest is built in a dense shrub or low in a tree. Both parents incubate and feed the young. These birds raise two or three broods in a year. They are able to call in up to 3000 distinct songs. The male sings a series of short repeated melodious phrases from an open perch to defend his territory and is also very aggressive in defending the nest.

Conservation and threats

Although this bird is widespread and still common, it has declined in numbers in some areas due to loss of suitable habitat.

The Brown Thrasher is the official state bird of Georgia, and the inspiration for the name of Atlanta's National Hockey League team, the Atlanta Thrashers.

The Brown Thrasher (Toxostoma rufum), sometimes erroneously called the Brown Thrush,[2] is a bird in the Mimidae family, a group that also includes the New World catbirds and mockingbirds.

Description

The Brown Thrasher is bright reddish-brown above with thin, dark streaks on its buffy underparts. Its long rufous tail is rounded with paler corners. Eyes are a brilliant gold. Adults average about 11.5 in (29 cm) long with a wingspan of 13 in (33 cm), and have an average mass of 2.4 oz (68 g).[3]

Habitat and range

It is found in thickets and dense brush, often searching for food in dry leaves on the ground. It also enjoys the convergence of mowed to unmowed lawns, particularly if there are ample shrubs or shrubby trees IE; fruit orchards that the undergrowth is left undisturbed. It also enjoys perennial gardens and can be seen jumping from the ground to catch insects on flowers and foliage. Its breeding range includes the United States and Canada east of the Rocky Mountains. It is a partial migrant, with northern birds wintering in the southern USA, where it occurs throughout the year. There is a single British record of this unlikely transatlantic vagrant.
