Justification of Red List Category
This species's once relatively large population has undergone a rapid decline (owing to habitat loss and degradation, and hunting) which is projected to continue into the future. For this reason it is listed as Vulnerable.
A recent extrapolation estimates that all remaining habitat could support a total population of c. 91,000 individuals, although this figure is declining rapidly and this trend is likely to continue (Eisermann et al. 2006).
The area of remaining habitat is declining rapidly and this trend is likely to continue (Eisermann et al. 2006). Habitat alteration and hunting pressure are the principal threats, both of which are increasing owing to an expanding human population. The species is therefore suspected to be declining rapidly.
Penelopina nigra inhabits wet premontane and montane broad-leaved forests of subtropical and temperate zones on Pacific and Caribbean slopes of south Mexico (uncommon and local [Eisermann et al. 2006], but moderate numbers in El Triunfo Biosphere Reserve [Gómez de Silva et al. 1999]), Guatemala (still locally common), Honduras, north-central Nicaragua (uncommon and rather local in both) and El Salvador (local [Howell and Webb 1995a, del Hoyo 1994, Vannini and Rockstroh 1997, K. Eisermann in litt. 2007]) . It can occur at densities of 30 birds/km2 and is probably more common than sightings suggest (del Hoyo 1994, Vannini and Rockstroh 1997). Suitable habitat in Guatemala, the apparent global stronghold, has been reduced to under c.10,000 km2, which is less than half its original extent (Vannini and Rockstroh 1997). Since 1990, it has been confirmed from 53 sites throughout its range (Eisermann et al. 2006).
It inhabits the most humid and densely forested slopes of Chiapas Montane Forest, Chimalapas Montane Forest, Central America Montane Forest and Central America Pine-Oak Forest (Eisermann et al. 2006). Although it is mainly restricted to cloud forest and pine-oak forests, it has also been recorded in mature cypress plantations and low canopy secondary forest (Eisermann et al. 2006). It forages singly, in pairs or small groups, often at twilight, on berries and other fruits from the upper forest canopy to the forest floor (K. Eisermann in litt. 2012).
Habitat alteration and hunting pressure are the principal threats. The human population is growing rapidly within the species's range (Eisermann et al. 2006). Forest is cleared for agriculture, particularly coffee plantations and maize fields, but also for plantations of leather leaf ferns (Rumohra adiantiformis) and ponytail (Beaucarnea spp.) (K. Eisermann in litt. 2007), and to a lesser extent for mining (O. Komar in litt. 2007). However, in Guatemala about 50% of the species range are used or planned for exploration and opencast mining (K. Eisermann in litt. 2012). Climate change may threaten the species in the future (O. Komar in litt. 2007), probably through altitudinal shifts in habitat.
Conservation Actions Underway
At several private reserves in Guatemala, the species's stronghold, habitat is protected and hunting is prevented (Eisermann et al. 2006). In Alta Verapaz, fire-protection zones adjacent to primary cloud forest were established by planting fruit trees, reducing the risk of forest fires from corn plots (K. Eisermann in litt. 2007). Short-term habitat protection is achieved by providing incentives for forest conservation and reforestation (K. Eisermann in litt. 2007). Hunting of the guan is prohibited by law in Mexico, Guatemala and El Salvador (Eisermann et al. 2006, O. Komar in litt. 2007, K. Eisermann in litt. 2012).
59-65 cm. Marked sexual dimorphism. Adult males are relatively small, all black and have bright red legs, bill and dewlap. Females are larger, brown, profusely barred and lack the dewlap. Similar spp. Can be confused with Penelope purpurascens, which also has red dewlap and occurs in some cloud forests. From Crypturellus tinamous and Dendrortyx wood-partridges, which also have red legs, by long tail.
