The Andean teal (Anas andium) is a South American species of duck. Like other teals, it belongs to the diverse genus Anas; more precisely it is one of the "true" teals of subgenus Nettion.Carboneras (1992), Johnson & Sorenson (1999), Johnson et al. (2000) It is restricted to the Andean highlands of Colombia, Venezuela, and Ecuador. It inhabits freshwater wetlands, preferring palustrine habitat to rivers. It is not considered threatened by the IUCN.
Taxonomy
Mitochondrial DNA sequence data is most similar to that of the very different-looking green-winged teal.Johnson & Sorenson (1999); see there for a discussion of the crecca-carolinensis-flavirostris group's phylogeny. Apart from the mystifying relationship with the red-and-green-headed teals, it altogether most resembles the Indian Ocean radiation of teals.
Traditionally, there are 2 subspecies:
- Mérida teal, Anas andium altipetens (Conover, 1941) – highlands of north-west Venezuela and adjacent parts of Colombia.
- nominate, Anas andium andium (Sclater & Salvin, 1873) - highlands of Colombia and Ecuador.
This species and the yellow-billed teal are sometimes considered conspecific under the name speckled teal (A. flavirostris), but increasingly taxonomists treat the two as distinct species. When split, the scientific name A. flavirostris is restricted to the yellow-billed teal.Van Remsen (2008)
