Taxonomy

Subspecies

Six subspecies are recognized in this widespread species^[1]:

• T. a. anabatinus:

• Atlantic slope of south-eastern Mexico to Guatemala, Belize and Honduras

• T. a. saturatus:

• Atlantic slope of Nicaragua to Costa Rica and extreme western Panama

• T. a. coronatus:

• Central and eastern Panama (Veraguas to Dari‚n) and north-western Colombia

• T. a. intermedius:

• Pacific slope of western Colombia and Ecuador
  

• T. a. gularis:

• Extreme north-western Venezuela (T chira) and (? adjacent north-eastern Colombia)

• T. a. aequatorialis:

• Foothills of south-eastern Colombia, eastern Ecuador and extreme northern Peru

Habitat

Humid to wet woodland in foothills and lower slopes of mountains.

Behaviour

Breeding

A deep cup shaped nest is built high in a tree and 2 brown speckled white eggs are laid. Both sexes build the nest, incubate the eggs and care for the young.

Diet

The diet includes insects and other arthropods. Often participate in mixed species flocks when feeding.

Vocalisation

Restall quote sources for saying that the subspecies east and west of the Andes differ in vocalizations, and therefore probably are different species.
