The grey-cowled wood rail or grey-necked wood rail (Aramides cajaneus; also gray-) is a species of bird in the family Rallidae, the rails. It lives primarily in the forests, mangroves, and swamps of Central and South America. Of the two subspecies, A. c. avicenniae is found in southeastern Brazil, while the nominate is found throughout the portion of the range not occupied by the other subspecies. The species as a whole is usually found at elevations from sea level to 2,000 metres (6,600 ft), although some have been found above that. This bird's large range, along with its significant population, is why it is considered to be least-concern by the International Union for Conservation of Nature (IUCN). In some places, it is occasionally hunted and kept for food.
This bird, large for a wood rail, has both a grey head and neck. In the nominate, the back of the head has a brown patch. The upperparts are olive-green to dark brown. The chest and flanks are a rufous colour, with the belly, rump, and tail being black. The legs are coral-red, the bill is a bright greenish-yellow, and the eyes are red. The sexes are similar. The juveniles can be differentiated by their duller look, and the chicks have a black, downy appearance, brown head, and black beak. The subspecies A. c. avicenniae can be differentiated by its smaller size, lack of a brown patch at the back of the neck, and its lower back being toned slightly olive. The underparts are also pale.
The bird is monogamous; pairs can be found together throughout the year. During the breeding season, which usually lasts from March to August, the grey-cowled wood rail builds nests that can be found on flat branches and in thickets, usually at heights between 1 and 3 metres (3 and 10 ft). In these nests, there is a clutch consisting of three to seven eggs, incubated by both sexes. The chicks that hatch are precocial, able to move soon after hatching. This rail feeds on a wide range of foods, from molluscs to seeds. It is also known to feed on the faeces of giant otters. Wikipedia →

Possible
About 20% of wildlife watchers report a Gray-cowled Wood-Rail sighting in Recife on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 40th most-seen of the 90 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Gray-cowled Wood-Rail in Recife on a given day, against about 10% in April, June, September and November–December, the lowest months. That is one of Recife's wettest months, with about 210 mm of rain against 25 mm in November.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Gray-cowled Wood-Rail sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 29
Of the 29 cities where we can rate Gray-cowled Wood-Rail sightings, Recife ranks 4th at about 20%. The best odds are in Goiânia (Brazil, about 30%), Fortaleza (Brazil, about 20%) and Campo Grande (Brazil, about 20%).
Same family: Rallidae
The closest relatives of the Gray-cowled Wood-Rail that you can see in Recife (family Rallidae, Rails, Gallinules, and Coots) are American Purple Gallinule (about 20%), Common Moorhen (about 10%) and Rufous-sided Crake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gray-cowled Wood-Rail is recorded against all the birds logged in Recife (25 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
