About the Creamy-breasted Canastero

The rusty-vented canastero or creamy-breasted canastero (Asthenes dorbignyi) is a species of bird in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Argentina and Bolivia. The rusty-vented canastero's taxonomy is unsettled. The International Ornithological Committee (IOC) and BirdLife International's Handbook of the Birds of the World (HBW) assign it two subspecies, the nominate A. d. dorbignyi (Reichenbach, 1853) and A. d. consobrina (Hellmayr, 1925). The South American Classification Committee of the American Ornithological Society and the Clements taxonomy include three more, A. d. arequipae (Sclater & Salvin, 1869), A. d. usheri (Morrison, A.R.G., 1947), and A. d. huancavelicae (Morrison, A.R.G., 1938). The IOC and HBW treat arequipae as a separate species, calling it the "dark-winged" and "Arequipa" canasteros respectively. The IOC treats huancavelicae as the pale-tailed canastero with usheri as a subspecies of it. HBW separately treats huancavelicae as the "Huancavelicae canastero" and usheri as the "white-tailed canastero".

To further complicate matters, all five of these taxa have plumage, morphological, vocal, behavioral... Wikipedia →
