VU
Yellow-green Finch Pselliophorus luteoviridis

Justification
This species is classified as Vulnerable because it is known from a small number of locations in a small range, within which habitat is now declining.

Taxonomic source(s)

Identification
17 cm. Stocky, dusky finch. Dull olive-green with black cap, wings and tail. Dusky grey sides of head and throat. Bright yellowish-olive underparts, but duller on flanks. Conspicuous bright yellow thighs and bend of wing. Similar spp. Sooty-faced Finch Lysurus crassirostris is more olive, lacks yellow thighs, black head and wings and has white moustache. Voice High pitch squeaky chattering and tsweet tsweet calls

Distribution and population
Pselliophorus luteoviridis is restricted to west and central Panama in the Serranía de Tabasará (Chiriquí, Veraguas and probably Bocas del Toro and Coclé). It has been recorded at Fortuna Forest Reserve, Cerro Flores and Cerro Colorado (adjacent peaks of the Cerro Santiago massif), and above Santa Fe and Chitra (Cerro San Antonio) (Ridgely and Gwynne 1989, Angehr and Jordán 1998, Angehr 2003), where it is scarce and poorly known. It probably also occurs in Omar Torrijos Herrera National Park (Angehr 2003).

Population justification
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.

Trend justification
A slow and on-going population decline is suspected based on the rate of habitat loss within the species's range.

Ecology
It inhabits highland cloud-forest, borders and clearings, at elevations of 1,200-1,800 m.

Threats
Only isolated patches of forest remain in east Chiriquí, and the Serranía de Tabasará is generally threatened by clearance for coffee plantations, cattle-grazing, overuse of pesticides and fires (Alvarez-Cordero et al. 1994). The core of its range around Cerro Santiago (in the Ngobe-Bugle Comarca (indigenous homeland)) is undergoing increasingly rapid deforestation owing to subsistence agriculture and cattle raising, and deforestation has now reached the continental divide. Deforestation is now occurring at the higher elevations favoured by the species, even within the boundaries of protected areas (Angehr 2003).

Conservation Actions Underway
It occurs in Fortuna Forest Reserve and Santa Fe National Park (Angehr 2003). It may also occur in Omar Torrijos Herrera National Park (Angehr 2003). The Panama Audubon Society has discussed a protected area with representatives from the Comarca, but no action has been taken as yet (G. Angehr in litt. 2007). Conservation Actions Proposed
Survey to determine its population and distribution, especially in areas between known sites. Research the species's ecological requirements. Enforce better protection of known sites. Monitor the extent and rate of deforestation.
