Range Description

Cephalopterus glabricollis breeds locally on the Caribbean slope of the Cordilleras de Guanacaste, Tilarn and Talamanca in Costa Rica, and contiguous mountains in Panama, east to the Fortuna area, Bocas del Toro and Chiriqu (Collar et al. 1992). In the non-breeding season, it descends to the foothills and lowlands of the Caribbean slope of Costa Rica and southern Nicaragua (Mnera-Roldn et al. 2007), and in Panama it occurs east to Veraguas and Cocl (Ridgely and Gwynne 1989, Angehr and Jordn 1998). Isolated records from the Dota mountains, Costa Rica (Slud 1964) and from the Cordillera de Tol, Panama (Wege 1993) likely correspond to the Caribbean side of those mountains or to the continental divide. It is now uncommon to rare and local throughout its range (Ridgely and Gwynne 1989, Stiles and Skutch 1989). This speciess breeding population in Costa Rican Important Bird Areas (IBAs) was assessed in 2007 and estimated at 740-1,430 mature individuals (J. Criado et al. in litt. 2007); however, in 2009 this was revised to 190-330 mature individuals (Snchez et al. 2009). In contrast, the 2007 estimate for the breeding population in the IBAs of Panama was given as 1,050-4,245 mature individuals, which is regarded by some as an overestimate (J. Criado et al. in litt. 2007), and is limited by a lack of sufficient data from the core of its likely range in Panama, La Amistad International Park, where its breeding areas are mostly inaccessible (G. Angehr in litt. 2011). On the basis of this information, the species's total population is conservatively estimated at fewer than 2,500 mature individuals, and it is suspected to be in rapid decline owing to on-going forest clearance and degradation (G. Angehr in litt. 2011, Unin de Ornitlogos de Costa Rica in litt. 2011).
