Tapichalaca, Zamora-Chinchipe, SE Ecuador, June 2019

Very local in Zamora-Chinchipe in far southern Ecuador and, as confirmed in 2006, adjacent parts of Cajamarca in northern Peru.
Rare and with a highly restricted range, but it has proven difficult to locate and undiscovered localities where it occurs could exist. Significant sections of its distribution are within the Tapichalaca Biological Reserve and the adjacent Podocarpus National Park, but the latter - at least - remain highly threatened by illegal logging and gold mining. It is currently considered endangered by BirdLife International.

[edit] Taxonomy

Only discovered in 1997 and described in 1999. Its species name, ridgelyi, refers to the discoverer, Robert S. Ridgely, who also played a fundamental part in the establisment of the Tapichalaca Biological Reserve.
This is a monotypic species.
Closest relatives are probably Pale-billed Antpitta and Chestnut-naped Antpitta.

[edit] Habitat

Humid montane forest. Prefers steep slopes.
Occurs at 2300 - 2680m.

[edit] Behaviour

Feeds on arthropods (milipedes, beetles, ants and larvae).
As other antpittas it is highly elusive and typically very difficult to see, but can become more "tame" if regularly feed at a specific locality. Based on timing of males' song, it is suspected that breeding is in October to November.
Presumably a resident species.
