Ecuadorian seedeater

The Ecuadorian seedeater (Amaurospiza aequatorialis) is a species of bird in the cardinal family Cardinalidae. It is found in the Andes in south-western Colombia through Ecuador to northern Peru. This species was formerly treated as a subspecies of what was the blue seedeater and is now Cabanis's seedeater.

Taxonomy

The Ecuadorian seedeater was formally described in 1888 by the English ornithologist Richard Bowdler Sharpe based on specimens collected in Ecuador. He coined the binomial name Amaurospiza aequatorialis.[1] The specific epithet is Late Latin for "equatorial", a name commonly used for species from Ecuador, ecuador means "equator" in Spanish.[2]

This species was generally treated as a subspecies of the blue seedeater with the trinomial name Amaurospiza concolor aequatorialis.[3] A molecular phylogenetic study published in 2014 found that Amaurospiza concolor concolor from Central America was genetically distinct from Amaurospiza concolor aequatorialis from Ecuador.[4] Based on these results the blue seedeater was split. The nominate subspecies Amaurospiza concolor concolor was given the common name Cabanis's seedeater and Amaurospiza concolor aequatorialis became the Ecuadorian seedeater Amaurospiza aequatorialis. The Ecuadorian seedeater is monotypic: no subspecies are recognised.[5]
