Choco Poorwill Nyctiphrynus rosenbergi

Justification
This species is classified as Near Threatened because it is suspected to be undergoing moderately rapid population declines owing to habitat loss.

Taxonomic note
Nyctiphrynus ocellatus (Sibley and Monroe 1990, 1993) has been split into N. ocellatus and N. rosenbergi following SACC (2005).

Distribution and population
Nyctiphrynus rosenbergi occurs in west Colombia (Chocó, Valle, Nariño and possibly Cauca) and north-west Ecuador (Esmeraldas, north-west Pichincha and south-west Imbabura) (Ridgely and Greenfield 2001) where it is relatively common but declining due to widespread habitat loss.

Population justification
The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).

Trend justification
A moderately rapid and on-going decline is suspected owing to habitat loss.

Ecology
It occurs in very humid lowland evergreen forest and edge, favouring treefalls and river edges, but also in adjacent secondary forest up to 900 m (Parker et al. 1996, Ridgely and Greenfield 2001).

Threats
Unplanned colonisation following the completion of roads, and massive logging concessions have cleared or degraded over 40% of its Chocó forests, and deforestation rates are accelerating (Salaman 1994). Currently, intensive logging, human settlement, cattle-grazing, mining and coca and palm cultivation all threaten its remaining forest habitat (Dinerstein et al. 1995). Large areas of its western Ecuadorian range are being purchased, denuded of forest and converted to industrial oil palm plantations (Sharpe 1999).

Conservation Actions Underway
None is known. Conservation Actions Proposed
Effectively protect core areas of remaining habitat. Study its ecology and its ability to persist in degraded and fragmented habitats. Attempt to obtain an accurate estimate of its population size and trends. Quantify extent of habitat losses. Establish new, community-owned or private protected areas as an alternative to loss of forest to commercial oil palm operations (Sharpe 1999).
