The rusty-vented canastero , or creamy-breasted canastero, (Asthenes dorbignyi) is a species of
Taxonomy and systematics
The rusty-vented canastero's taxonomy is unsettled. The
To further complicate matters, all five of these taxa have plumage, morphological, vocal, behavioral, and nest structure characteristics that may better place them in the thornbird genus Phacellodomus rather than Asthenes.[6]
This article follows the two-subspecies model.
Description
The rusty-vented canastero is 14.5 to 16.5 cm (5.7 to 6.5 in) long and weighs 17.5 to 24 g (0.62 to 0.85 oz). It is a medium-sized canastero. The sexes have the same plumage. Adults of the nominate subspecies have a light gray
Distribution and habitat
The nominate subspecies of the rusty-vented canastero is found in the Andes from Cochabamba Department in central Bolivia south into northwestern Argentina as far as Mendoza Province. Subspecies A. d. consobrina is found in the Andes of southwestern Bolivia's La Paz, Oruro, and Potosí departments. The species inhabits arid landscapes, especially scrublands and nearby woodlands.[7][8]
Behavior
Movement
The rusty-vented canastero is a year-round resident throughout its range.[1]
Feeding
The rusty-vented canastero's diet has not been detailed but is known to be mostly arthropods and include seeds. It forages on the ground and in low woody vegetation, usually singly or in pairs, and gleaning for its prey.[7]
Breeding
The nest of the nominate subspecies of the rusty-vented canastero is a globular mass of sticks, some of which are thorny, with an entrance near the top and a tunnel to the nest chamber. The chamber is lined with wool, feathers, and soft plant material. The nest is built in a shrub, a small tree, or on a columnar cactus, and several nests may be in one tree. Both sexes build the nest. The nest of subspecies A. d. consobrina has not been described. The species is thought to be monogamous. Small family groups roost in nests year-round. Nothing else is known about its breeding biology.[7]
Vocalization
The rusty-vented canastero's song "may begin with a series of introductory notes, but these apparently are not always given. The song then...accelerates and ascends, before descending and decelerating near the end". Its call has been described as a "wheezy, earthcreeper-like whee" and as a "rising, penetrating shreep! or whee". It usually sings from atop a bush or small tree.[7]
