Distribution
Three well separated populations:
Central America: Mexico, Belize, Guatemala, El Salvador, Honduras, and northern Nicaragua; secondly from Costa Rica to western Panama
South America: west of the Andes in Colombia and Ecuador
Taxonomy
More than one species may be involved.
Subspecies
Clements recognises the following subspecies [1]:
- A. v. variegaticeps: South Mexico (Guerrero and Veracruz) to western Panama. [often pale beneath with chest streaking muted or absent. Greater tendency to have a "collar"]
- A. v. temporalis: West slope of Western Andes of Colombia and Ecuador. [dark underneath, more strongly orange with strong chest streaking]
Other authors recognise subspecies schaldachi of south-west Mexico (e.g. refs [2], [3])
Habitat
Montane and lowland evergreen forests. Also tall second growth forests.
Behaviour
Diet
They eat a variety of insects, including moths and spiders.
Breeding
They are thought to be monogamous. Their clutch contains 2 eggs, which are laid at the bottom of an old woodpecker nest hole.
