Listed as Endangered because its extent of occurrence (EOO) is 4,391 km2, it is known from four locations and the population is severely fragmented, and there is continuing decline in the extent and quality of habitat due to agricultural activities in the Cordillera Occidental of Colombia.

Geographic Range [top]

Range Description:This species is known from four locations in the Antioquia, Risaralda, Valle del Cauca and Chocó Departments, on the western flank of the western Andes in Colombia between 1,400 and 2,100 m Asl. Its EOO is 4,391 km2 and there are four threat-defined locations.

Population [top]

Population:It is a rare species. There is only one recent record (2015) from Parque Nacional Orquideas, in Urrao. It is very likely that the majority of the population is in small sub-populations with no exchange of individuals among them (Colombia Red List Assessment Workshop August 2016). Therefore, the population is considered to be severely fragmented.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:Yes

Habitat and Ecology [top]

Habitat and Ecology:It inhabits vegetation associated with streams in sub-Andean forests. Some specimens of the species were found in mature forest, far from water bodies, suggesting a possible migration of adults into the forest during the non-breeding season (Rada and Guayasamin 2008). Males have been observed calling on branches 1.5–1.8 m above the ground. Its breeding habits have not been observed, although it presumably breeds in streams.
Systems:Terrestrial; Freshwater
Continuing decline in area, extent and/or quality of habitat:Yes
Movement patterns:Not a Migrant

Use and Trade [top]

Use and Trade: There are no records of this species being utilized.

Threats [top]

Major Threat(s): The main threat to the species is the expansion of the agricultural frontier.

Conservation Actions [top]

Conservation Actions: Conservation Actions
Its range includes Parque Nacional de Las Orquídeas, Parque Nacional Natural Tatamá, and Reserva Montezuma.

Conservation Needed
Improved habitat protection may be required if agricultural activities are encroaching into the boundaries of the protected areas.

Research Needed
More information is needed on this species' distribution, population status, natural history, and threats.
