Yellow-throated form

Differ from the White-naped type in having yellow limited to the throat; the rest of the underside varies from pale gray washed brownish on flanks to white washed with olive.

[edit] Distribution & Taxonomy

Two groups which differ remarkably and are sometimes treated as two species:

[edit] White-naped Brush-Finch

Limited to eastern Mexico (and possibly adjacent Guatemala). There is no overlap in range with Yellow-throated Brush-Finch.

  • A.a. albinucha

[edit] Yellow-throated Brush-Finch

This form is found from southern Mexico to Panama and Colombia.

  • A.a. gutturalis (if considered a full species, this is the nominate subspecies of the species Atlapetes gutturalis)
  • A.a. griseipectus
  • A.a. fuscipygius
  • A.a. parvirostris
  • A.a. brunnescens
  • A.a. coloratus
  • A.a. azuerensis

[edit] Habitat

Forest edge, clearings, and high-altitude shrubland, sometimes in areas best described as cloud forest. In Mexico often in areas with mixture of pine and other trees.

[edit] Behaviour

Likes to keep hidden except when singing, and probably not easy to see even then. Mostly seeks food on the ground or low above the ground.
