Synonyms [1] [2]

Canasteros and thistletails are small passerine birds of South America belonging to the genus Asthenes. The name "canastero" comes from Spanish and means "basket-maker", referring to the large, domed nests these species make of sticks or grass. They inhabit shrublands and grasslands in temperate climates from the lowlands to the highlands. They feed on insects and other invertebrates gleaned from the ground or the low vegetation.

Taxonomy

The genus Asthenes was introduced in 1853 by the German naturalist Ludwig Reichenbach. [3] The name is from Ancient Greek asthenēs meaning "insignificant". [4] The type species was designated by George Robert Gray in 1855 as Synallaxis sordida Lesson. [5] [6] This taxon is now considered to be a subspecies of the sharp-billed canastero (Asthenes pyrrholeuca sordida). [7]

In 2010, it was discovered that the thistletails and the Itatiaia spinetail, formerly placed in their own genera (Schizoeaca and Oreophylax, respectively), are actually part of a rapid radiation of long-tailed Asthenes. [2] At the same time, four species, the cactus, dusky-tailed, Steinbach's and Patagonian canasteros, were split off into the new genus Pseudasthenes . [2]

Species

The genus contains 29 species: [7]

Description

They are typically 15–18 centimetres (5.9–7.1  in ) long and slim with long tails and thin, pointed bills. They are mostly dull and brown in colour but vary in tail pattern and presence of streaking. They have trilling songs.

Distribution and habitat

Most species occur in open country, including mesic to arid scrublands and grasslands. Some species inhabit dry forests. Only three species are migratory. [8]

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.

<i>Synallaxis</i> Genus of birds

Synallaxis is a genus of birds in the ovenbird family, Furnariidae. It is one of the most diverse genera in the family and is composed of small birds that inhabit dense undergrowth across tropical and subtropical habitats in the Neotropical region. Some species show contrasting plumage patterns involving rufous crown and wing patches and black throat patches but they are difficult to see as they keep ensconced in vegetation most of the time. Most species show the long graduated tail with pointy feathers that is typical of spinetails. They are also characterized by constructing large domed nests with stick, including a long entrance tube. Some species can be difficult to distinguish from one another on the basis of their plumage, but can be told apart by their vocalizations, which can be quite distinctive.

<span class="mw-page-title-main">Tit-spinetail</span> Genus of birds

Tit-spinetails are small passerine birds of the genus Leptasthenura, belonging to the ovenbird family Furnariidae. They are found in South America, particularly the southern and Andean parts of the continent. They are somewhat similar to birds of the tit family in their shape and feeding behaviour, hence the first part of their name. The "spinetail" part of their name refers to their long, pointed tail feathers. Tit-spinetails have short rounded wings, short pointed bills and are mainly brown in colour. Their nests are built in holes or in the old nests of other birds.
