Arremon is a genus of neotropical birds in the family Passerellidae. With the exception of the green-striped brushfinch which is endemic to Mexico, all species are found in South America, with a few reaching Central America. These sparrows are found in lowland woodlands and forests where they usually forage on the ground.

2011年2月1日 · The genus Buarremon (Aves, Emberizidae), as traditionally defined, consists of three morphologically similar species: Buarremon torquatus, Buarremon brunneinucha, and Buarremon virenticeps. However, a recent study rejected the monophyly of the genus.

2008年4月1日 · The genus Buarremon comprises a group of Neotropical finches that inhabits humid montane forests from Mexico to Argentina. Merged into Atlapetes by Hellmayr (Hellmayr, 1938), but recently recognized again based on molecular systematic studies (García-Moreno and Fjeldså, 1999, Hackett, 1992), they also differ in behavior, distribution, and ...

The grey-browed brushfinch, or gray-stripped brushfinch, (Arremon assimilis) is a species of bird in the family Passerellidae. It lives in the undergrowth of humid forest, especially near the edges, at altitudes of 300 to 1,200 metres (980 to 3,940 ft) in the Andes Mountains of Venezuela, Colombia, Ecuador, and most of Peru.

The Buarremon brush-finches represent a complex suite of populations distributed in the montane New World Tropics from Mexico south to South America. Traditional taxonomic arrangements have separated populations of this genus into three species, based on plumage variation, although plumage patterns …

The chestnut-capped brushfinch (Arremon brunneinucha) is a Neotropical passerine bird in the New World sparrow family, Passerellidae. Until recently, it was generally placed in the genus Buarremon, [1] while it occasionally has been placed in Atlapetes.

Here, we apply some of these methods to reconstruct the phylogeny of Buarremon and near relatives, a group in which phylogenetic analyses of mitochondrial DNA sequences produced results that were inconsistent with relationships implied by a taxonomy based on variation in external phenotype.

AI•STRACT.--Two species of Andean brush-finches, Buarremon (formerly Atlapetes) torquatus and B. brunneinuchu$, show an interdigitating pattern of distribution in the Andes that we interpret as the result of competition between them.

2008年4月1日 · The Buarremon brush-finches represent a complex suite of populations distributed in the montane New World Tropics from Mexico south to South America. Traditional taxonomic arrangements have separated populations of this genus into three species, based on plumage variation, although plumage patterns are well known to exhibit homoplasy.
