Dark-backed wood-quail<br />

(Odontophorus melanonotus)<br />

Vulnerable B1+2a,b,c,e<br />

This species has a small range with recent records from<br />

few sites. Available habitat, <strong>and</strong> presumably the<br />

population, is declining. The species, therefore, qualifies<br />

as Vulnerable<br />

Range <strong>and</strong> population: The dark-backed wood-quail has a<br />

very small range in the Chocó (West Andes) of northwest<br />

Ecuador (Esmeraldas, Carchi, Imbabura, Pichincha, <strong>and</strong><br />

Cotopaxi) <strong>and</strong> southwest Colombia (Nariño) (Best et al.<br />

1996, Hilty <strong>and</strong> Brown 1986, N. Krabbe in litt., McGowan<br />

et al. 1995). The population is estimated at 10,000–20,000<br />

individuals <strong>and</strong> declining (Salaman <strong>and</strong> Strewe in prep.).<br />

Although considered rare in Ecuador (Ridgely et al. 1998),<br />

it remains common in Río Nambí <strong>and</strong> La Planada Nature<br />

Reserves, Colombia (Salaman <strong>and</strong> Strewe in prep.) <strong>and</strong><br />

Mindo-Nambillo Protected Forest <strong>and</strong> Maquipucuna<br />

Reserve, Ecuador (N. Krabbe in litt.).<br />

Ecology: This wet subtropical forest specialist occurs<br />

exclusively in undisturbed, closed-canopy forest at 1,100–<br />

1,900m. It is typically found in groups of 2–10 individuals,<br />

which are particularly vocal at dawn during the wet season.<br />

Recent hatchlings have been recorded in July <strong>and</strong> August. It<br />

feeds on terrestrial invertebrates <strong>and</strong> fruit (N. Krabbe in litt.).<br />

Threats: Deforestation <strong>and</strong> hunting for food are the major<br />

threats to this species (McGowan et al. 1995). Unplanned<br />

colonisation, following the completion of roads <strong>and</strong> massive<br />

logging concessions, has been the primary cause of habitat<br />

loss. Deforestation rates are accelerating within its range<br />

primarily due to intensive logging, human settlement, <strong>and</strong><br />

cattle grazing. Forests at these elevations are less threatened<br />

than those in the lowl<strong>and</strong> Chocó region, but habitat loss is<br />

occurring below 2,000m, especially along new roads, <strong>and</strong><br />

the Cali-Buenaventura <strong>and</strong> Pasto-Tumaco Highways<br />

(Salaman <strong>and</strong> Stiles 1996).<br />

Conservation: It occurs in Río Nambí <strong>and</strong> La Planada<br />

Nature Reserves, Colombia, <strong>and</strong> Mindo-Nambillo<br />

Protected Forest, Los Cedros Biological Reserve, Las<br />

Tangaras <strong>and</strong> Maquipucuna Reserve, Ecuador (Best et al.<br />

1996, P. Salaman in litt.). Both of the protected areas in<br />

Colombia suffer serious illegal logging within their<br />

boundaries <strong>and</strong> have significant unresolved l<strong>and</strong> disputes,<br />

encompassing over one-third of La Planada <strong>and</strong> half of<br />

Río Nambí (R. Strewe pers. comm.).<br />

Targets:<br />

• Conduct a complete distributional survey to determine<br />

its range <strong>and</strong> numbers more accurately.<br />

• Map remaining habitat <strong>and</strong> assess the extent <strong>and</strong> rate of<br />

habitat loss.<br />

Tacarcuna wood-quail<br />

(Odontophorus dialeucos)<br />

Vulnerable D2<br />

The very small occupied range of this species, combined with<br />

some potential threats, qualifies it as Vulnerable.<br />

Range <strong>and</strong> population: The Tacarcuna wood-quail was<br />

discovered in 1963 <strong>and</strong> is only known from Cerros Mali<br />

<strong>and</strong> Tacarcuna on the Tacarcuna Ridge in Darien, extreme<br />

east Panama <strong>and</strong> adjacent Chocó, northwest Colombia<br />

(Ridgely <strong>and</strong> Gwynne 1989, Wege 1996). Its area of<br />

occupancy is estimated at 100km2 (Wege 1996). It is fairly<br />

common in suitable habitat in Panama (Ridgely <strong>and</strong><br />

Gwynne 1989).<br />

Ecology: This is a very poorly known terrestrial bird of<br />

humid forests, found at elevations of 1,050–1,450m<br />

(Ridgely <strong>and</strong> Gwynne 1989, Wege 1996).<br />

Threats: Hunting for food, <strong>and</strong> habitat clearance <strong>and</strong><br />

degradation resulting from mining, agriculture, <strong>and</strong><br />

cultivation of coca affect birds in this region (Alvarez-<br />

Cordero et al. 1994). However, these threats are probably<br />

not yet factors within this species’ altitudinal range.<br />

Completion of the Pan-American Highway link through<br />

Darién could lead to severe, long-term damage to the<br />

forest of the Tacarcuna Ridge (Alvarez-Cordero et al.<br />

1994, Wege 1996).<br />

Conservation: Darien National Park, Panama, protects all<br />

but the small Colombian part of its range (Wege 1996).<br />

However, legal protection has not halted habitat loss at<br />

lower altitudes (Wege 1996).<br />

Targets:<br />

• Conduct a complete distributional survey to assess status<br />

<strong>and</strong> habitat preferences.<br />

• Map remaining habitat <strong>and</strong> assess the extent <strong>and</strong> rate of<br />

encroaching habitat loss.<br />

White-breasted guineafowl<br />

(Agelastes meleagrides)<br />

Vulnerable A1c,d; A2c,d<br />

This species is classified as Vulnerable because it is inferred<br />

to have suffered a rapid population decline over the last 10<br />

years, based on the rate of forest destruction throughout its<br />
