The sage thrasher (Oreoscoptes montanus) is a medium-sized passerine bird from the family Mimidae, which also includes mockingbirds, tremblers, and New World catbirds. It is the only member of the genus Oreoscoptes. This seems less close to the Caribbean thrashers, but rather to the mockingbirds instead (Hunt et al. 2001, Barber et al. 2004).

Oreoscoptes montanus are pale grey-brown on the upperparts and white with dark streaks on the underparts. They have a slim straight relatively short bill, yellow eyes and a long tail, although not as long as that of other thrashers.

Measurements: [2]

Breeding

As its name suggests, this bird breeds in western North America, from southern Canada to northern Arizona and New Mexico. Its breeding habitat is in areas with dense stands of sagebrush and rarely in other shrubby areas. Their nests are made of twigs, rootlets and bark strips, lined with fine rootlets. [3] The female lays 4 or 5 eggs in a twiggy cup nest built in a low bush. Both parents incubate and feed the young birds.

Migrating

In winter, these birds migrate to the southernmost United States and Mexico, including the Baja Peninsula, north and south.

Diet

They mainly eat insects in summer; they also eat berries, especially in winter. They usually search for insects on the ground in brushy locations.

Vocalization

The male bird sings a series of warbled notes to defend his nesting territory.

Conservation

These birds have declined in some areas where sagebrush has been removed but are still common where suitable habitat remains. The continued decline of sagebrush habitats in western North America is cause for alarm for this and other sagebrush dependent species.

The mimids are the New World family of passerine birds, Mimidae, that includes thrashers, mockingbirds, tremblers, and the New World catbirds. As their name suggests, these birds are notable for their vocalization, especially some species' remarkable ability to mimic a wide variety of birds and other sounds heard outdoors. They are commonly referred to as mimic thrushes but are not, in fact, thrushes.

<span class="mw-page-title-main">Northern mockingbird</span> Species of bird

The northern mockingbird is a mockingbird commonly found in North America. This bird is mainly a permanent resident, but northern birds may move south during harsh weather. This species has rarely been observed in Europe. This species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae as Turdus polyglottos. The northern mockingbird is known for its mimicking ability, as reflected by the meaning of its scientific name, "many-tongued mimic". The northern mockingbird has gray to brown upper feathers and a paler belly. Its tail and wings have white patches which are visible in flight.

<span class="mw-page-title-main">Gray catbird</span> Species of bird

The gray catbird, also spelled grey catbird, is a medium-sized North American and Central American perching bird of the mimid family. It is the only member of the "catbird" genus Dumetella. Like the black catbird, it is among the basal lineages of the Mimidae, probably a closer relative of the Caribbean thrasher and trembler assemblage than of the mockingbirds and Toxostoma thrashers. In some areas it is known as the slate-colored mockingbird.

The curve-billed thrasher is a medium-sized mimid native to most of Mexico and to the deserts of southwestern United States. It is a non-migratory species, and throughout most of its range it is the most common desert thrasher. Several subspecies have been classified since 1827, though there is no consensus on the number. Allopatric speciation is believed to have played a major role in the variations of the curve-billed. It is grey-brown overall with a slightly curved bill, and is similar in appearance to the related Bendire's thrasher. It generally resides in desert regions of the United States and Mexico, but can inhabit areas predominately populated by humans.

Most recent authorities recognize two species in the genus, but some split each into two species, bringing it to four species:

At 19–20.5 cm (7.5–8.1 in) in length and 31.6–42 g (1.11–1.48 oz) in mass, it is the smallest of the mimids. Sexes appear similar, with glossy black plumage, black legs and bill, and dark brownish eyes. The species is endemic to the Yucatán Peninsula, and is found as far south as Campeche, northern Guatemala and northern Belize. Although there are historical records from Honduras and the US state of Texas, the species is not now known to occur in either location. It is found at low elevations in semi-arid to humid habitats ranging from shrubland and abandoned farmland to woodland with thick understory, and is primarily sedentary.
