Canastero

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 feed on insects and other invertebrates.

Taxonomy and systematics

There are thirty species which belong to the genus Asthenes in the ovenbird family Furnariidae.[3] 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 list

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 and scrubland in southern South America and the Andes.

gollark: We could probably manage decently high populations without removing vast quantities of environment with better management and application of existing technology, but nobody is doing this.
gollark: I mean, we chlorinate water now because of that sort of thing, you would have to get around all of that.
gollark: If you wanted to wipe out all humans for some reason, it would probably be quite effective to make a virus with reaaally delayed fatal effects which spreads well in the meantime.
gollark: Somewhat open, they aren't telling people all the production details I guess. Not sure if anyone was asking for that.
gollark: The Moderna one *is* effectively open but nobody has actually done anything with it.
