range_
range_map_caption = Known Ecuadorian range in blue. Now also confirmed from adjacent Peru.The Jocotoco Antpitta, "Grallaria ridgelyi", is an
endangered bird fromEcuador andPeru . It is a large (150-200 g) ground antbird with a striking head pattern with tufts of white plumes beneath the eyes, and has a song similar to the hooting of theRufous-banded Owl . Its closest relative appears to be theChestnut-naped Antpitta and thePale-billed Antpitta , with which it forms a group of antpittas with uniform breast plumage and smoky-grey flanks (Krabbe "et al." 1999).As with other true antpittas, assignment to the
Formicariidae family is in need of verification (Rice 2005)."G. ridgelyi" inhabits only wet, mossy forest with ample "
Chusquea "bamboo stands and silvery-leaved "Cecropia " trees. It is found at an altitude of 2,300 to 2,680meter s (Krabbe "et al." 1999). It was initially believed to be limited to the upperRio Chinchipe drainage inZamora-Chinchipe ,Ecuador , but in 2006 a population was discovered inCordillera del Cóndor in Cajamarca,Peru .This
species was only discovered in1997 , and scientifically described in1999 . To protect the presumably small population of this bird, theCerro Tapichalaca Biological Reserve was established on behalf of theFundación Jocotoco in1998 . It is presently known only from a very small number of locations and appears to be declining.Consequently, the
IUCN classifies it as Endangered (B1ab(i, ii,iii, v)). This means that based on currently available data, it is estimated to occur in no more than 5 locations over a total area of less than 5000 km², with both habitat quality and availability, and numbers declining, and some of thesubpopulation s in danger of disappearance. Due to its shyness and the call which might be mistaken for that of a Rufous-banded Owl, it could be more widespread than presently known, although surveys at several seemingly appropriate localties have failed to find any evidence of this species.This bird's
specific name honors theornithologist Robert S. Ridgely , who took part in the initial discovery of this species. Thecommon name refers to the local name of the bird, "jocotoco", which isonomatopoetic after the hooting calls and song (Krabbe "et al." 1999).References
