Xenops is a genus in the bird family Furnariidae, the ovenbirds. The genus comprises four species of xenops, all of which are found in Mexico, Central America and South America, particularly in tropical rain forests.

They are small birds with a longish tail, a laterally flattened bill with an upturned tip (except in the slender-billed xenops), brown back and buff or rufous wing stripe. They forage for insects on bark, rotting stumps or bare twigs, moving mechanically in all directions on the trunk like a woodcreeper, but without using the tail as a prop.

Together with the distinct great xenops (Megaxenops parnaguae), this genus forms the tribe Xenopini, which based on some recent studies belongs in the woodcreeper and xenops subfamily Dendrocolaptinae, [2] while others have found them to be part of the "traditional" ovenbirds. [3] A study from 2013 found that they should be a family distinct from both. [4]

Species

Formerly, the rufous-tailed xenops was placed in this genus, but it has been moved to the monotypic Microxenops . The following five species remain in the genus Xenops: [5]

Formicariidae is a family of smallish suboscine passerine birds of subtropical and tropical Central and South America known as antthrushes. They are between 10 and 20 cm in length, and are most closely related to the ovenbirds in the family Furnariidae, and the tapaculos in the family Rhinocryptidae. The family Formicariidae contains 12 species in two genera.

<span class="mw-page-title-main">Ovenbird (family)</span> Large family of small suboscine passerine birds

Ovenbirds or furnariids are a large family of small suboscine passerine birds found from Mexico and Central to southern South America. They form the family Furnariidae. This is a large family containing around 315 species and 70 genera. The ovenbird, which breeds in North America, is not a furnariid – rather it is a distantly related bird of the wood warbler family, Parulidae.

<span class="mw-page-title-main">Woodcreeper</span> Subfamily of birds

The woodcreepers (Dendrocolaptinae) comprise a subfamily of suboscine passerine birds endemic to the Neotropics. They have traditionally been considered a distinct family Dendrocolaptidae, but most authorities now place them as a subfamily of the ovenbirds (Furnariidae). They superficially resemble the Old World treecreepers, but they are unrelated and the similarities are due to convergent evolution. The subfamily contains 63 species in 16 genera.

The Tyranni (suboscines) are a suborder of passerine birds that includes more than 1,000 species, the large majority of which are South American. It is named after the type genus Tyrannus. These have a different anatomy of the syrinx musculature than the oscines, hence the common name of suboscines.

The many-colored rush tyrant or many-coloured rush tyrant is a small passerine bird of South America belonging to the tyrant flycatcher family, Tyrannidae. It is the only member of the genus Tachuris and is sometimes placed in a separate monotypic family. It inhabits marshland and reedbeds around lakes and rivers. It is particularly associated with stands of Scirpus. The nest is built among plant stems.

<i>Piprites</i> Genus of birds

Piprites is a genus of bird currently placed in the family Tyrannidae. Prior to 1971, the genus was placed in the family Pipridae; its designation was initially changed based on morphological evidence, and genetic evidence confirmed its placement in 2009. In 2013, it was proposed that Piprites was to be placed in the unique family Pipritinae. The proposition was declined by the Comité de Clasificación de Sudamérica, a part of the American Ornithological Society, and the proposed family was changed to be a unique subfamily of the genus. The genus is composed of three species native to the neotropical realm, with distributions ranging from the Caribbean coast of Guatemala, Central America, and southeastern Argentina.

<span class="mw-page-title-main">White-throated treerunner</span> Species of bird

The white-throated treerunner is a species of bird in the family Furnariidae. It is the only species in the genus Pygarrhichas. The white-throated treerunner is about 15 cm (5.9 in) long, with a stiff and rounded tail. The upperparts are dark brown, turning red on the lower back and tail and contrasting sharply with the throat and chest of a bright white. The rest of the underparts are coarsely mottled with white. The bill is long, slightly curved upwards. The general appearance is reminiscent of a nuthatch, although they are not directly related. Like the Sittidae, Furnariidae tirelessly scours the trunks and branches of old trees for the small arthropods that make up its food, spiraling up the trunks, or sometimes moving head down. The white-throated treerunner consumes small invertebrates found on bark and nests in tree cavities. Outside of the breeding season, it may form mixed-species foraging flocks with other bird species.
