Justification:
This species has a small range in which forest has been extensively cleared and fragmented. Despite inhabiting edge environments and even nesting in human-modified habitats, it appears intolerant of forest fragmentation, suggesting that it is declining. However, an elucidation of its habitat requirements or improved knowledge of its distribution, especially in Nicaragua, may result in the species being downlisted to Near Threatened.

Geographic Range [top]

Range Description:	Aphanotriccus capitalis occurs on the Caribbean slope in north Costa Rica and south Nicaragua. All Nicaraguan records are historical specimens collected near Lake Nicaragua or its outflow, río San Juan (Specimens in NHM per T. E. H. Stuart in litt. 2000). However, three specimens taken in 1896 are labelled "Río Coco", which, unless there are two Coco rivers, forms the border with Honduras and considerably extends the range northwards (Specimens in NHM per T. E. H. Stuart in litt. 2000). In Costa Rica, it is known from Volcán Orosí (northern tip of the Cordillera de Guanacaste), south to the Río Reventazón drainage, in the foothills between the Cordilleras Central and de Talamanca. It is not common anywhere, with most recent observations at Rancho Naturalista (east of Turrialba), La Selva Biological Reserve and their environs (Stiles and Skutch 1989, Costa Rica Gateway 1998, R. Behrstock in litt. 1999, P. Coopmans in litt. 1999, K. Erb in litt. 1999, N. Newfield in litt. 1999, M. Reid in litt. 1999, F. G. Stiles in litt. 1999, J. VanderGaast in litt. 1999, Van Gausig in litt. 1999).

Population [top]

Population:	The population size is preliminarily estimated to fall into the band 10,000-19,999 individuals. This equates to 6,667-13,333 mature individuals, rounded here to 6,000-15,000 mature individuals.
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits mature secondary and evergreen forest, usually in dense understorey vegetation on the forest edges, along forest streams and in natural forest clearings (Stiles and Skutch 1989, F. G. Stiles in litt. 1999, J. VanderGaast in litt. 1999). In La Selva, it has been recorded in cocoa plantations and similar "semi-open" areas (McDade et al. 1994), but is not known from small forest fragments. It ranges from the low foothills to c.900 m, and locally to 1,050 m (Stiles and Skutch 1989). The Nicaraguan localities are apparently in the lowlands, but specimens could have been collected in nearby hilly areas. Nests have been found in hollows of fairly large trees and in large, non-native bamboo stems (J. VanderGaast in litt. 1999).
Systems:	Terrestrial; Freshwater

Threats [top]

Major Threat(s):	Logging, conversion to banana plantations and cattle-ranch expansion have resulted in widespread forest clearance and severe fragmentation, particularly in Costa Rica (Stiles and Skutch 1989, Dinerstein et al. 1995, Harcourt and Sayer 1996).

Stiles in litt. 1999), and potentially Braulio Carillo National Park, Costa Rica, and Río Indio-Maíz Biological Reserve, Nicaragua. Rancho Naturalista is an ecotourism lodge where the species receives protection under current management practices (M. Reid in litt. 1999, J. VanderGaast in litt. 1999). Conservation Actions Proposed Survey to assess its population and distribution, especially in Nicaragua. Determine the extent to which it can use and maintain a population in unnatural habitats. Increase the area of suitable habitat within governmental and private protected areas.
