Description General Info
Description
The grey-cowled wood rail usually measures 33–40 centimetres (13–16 in) long and weighs 320–465 grams (11.3–16.4 oz), particularly large for a wood rail. The upperparts are olive-green to dark brown. The head and neck are medium-grey, blending into a brown patch at the back of the head. The eyes are red. The chest and flanks are rufous. The belly, rump, and tail are black. The legs are coral-red, while the bill is a bright greenish-yellow. The males and females are similar. Juvenile birds are similar to the adult but are duller in colour, with their belly sooty-black and flecked with buff. The juveniles also differ in that their bill and legs are dusky, and have brownish eyes. The chicks are black and downy, with a brownish head. Their dark eyes are lined with dull, reddish bare skin. The black bill has a flesh-coloured base, and a small, white egg tooth behind the tip of the upper mandible, as well as a very small one at the tip of the lower mandible. The subspecies avicenniae differs from the nominate by its smaller size. It also varies as its nape to back is a dull grey colour. The brown spot present at the back of the head of the nominate is also reduced or gone. The lower back is toned a slight olive, and the underparts are also slightly paler than the nominate, but without white feathers. Avicenniae's upper wing-coverts are also more greenish-grey. The similar but smaller rufous-necked wood rail can be differentiated from the grey-necked wood rail by the former's reddish head and neck with a grey upper back. This bird moults its remiges simultaneously. This moult occurs during the months from March to June.

Feeding Habits
This bird feeds at night, eating various invertebrates and small vertebrates. While in mangroves, it commonly feeds on crabs. Otherwise, it will generally feed on molluscs, arthropods, frogs, seeds, berries, palm fruits, and the occasional water snake. Maize, rice, and bananas are also viable food items for the grey-necked wood rail. It is also known to feed on the feces of giant otters at latrines. When eating snails, this rail will hammer at the shells to extract them. For berries, it will jump high to break off clusters of this fruit. After doing this, it will pick off the berries one by one and eat them. It uses its partially open bill to probe and move aside debris like leaf litter. It is generally wary and secretive, and selfish when mated. This manifests in warning its partner with threat displays to keep it at a distance. Even so, it has occasionally been seen to openly forage in short grass near thickets and in streams or muddy tracks.
General Info
Behavior
This bird can be seen to perch in both shrubbery and even trees, something characteristic of the forest rails. The grey-cowled wood rail rarely flies, although when it is flushed out, it will generally move to a branch close to the ground. If it is being observed, it is generally cautious.
Distribution Area
The grey-cowled wood rail is found in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, French Guiana, Guyana, Panama, Paraguay, Peru, Suriname, Trinidad and Tobago, Uruguay, and Venezuela. The nominate subspecies is cut off by the Andes Mountains and lives east of the range in Ecuador, Peru, and Bolivia; it is not found in the southeastern interior of Brazil. The subspecies avicenniae is found in coastal southeastern Brazil, around São Paulo. The grey-cowled wood rail's natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical mangrove forests, and subtropical or tropical swamps. The subspecies avicenniae, however, is almost completely restricted to mangrove forests. The grey-cowled wood rail can be found from sea level to elevations around 2,000 metres (6,600 ft), although some wanderers have been recorded at elevations up to 2,300 metres (7,500 ft) in Colombia.
Species Status
This rail is considered to be a least-concern species, according to the IUCN. The justification is this species' stable and large population, believed to be somewhere between five million and 50 million individuals. The grey-cowled wood rail also has a large extent of occurrence, estimated to cover 21.4 million square kilometres (8.3 million sq mi). It is common throughout its range, although it is adversely affected by destruction of its habitat.
