Rufous-necked Wood-Rail

How to find it

Look along mangrove edges, muddy banks and stream margins at dawn or dusk, when this secretive rail comes out to feed. A boat through mangrove channels is a sensible way to cover that habitat, as on the Tárcoles River at Carara. Listen first: the loud kip and kow duet can lead you to the bird before you see it. Be ready for a brief look, since views on a branch can be fleeting. Outside the northwest, a wood-rail is almost always the Russet-naped, so check the head colour.

How to recognise it

This is a medium rail, 29 to 33 cm long across its range. Learn it by a few plain marks:

Head, neck and breast: rufous brown, over the whole head rather than in a patch.

Upper back: a triangular gray patch that contrasts with the dull olive green back and wing coverts.

Throat: white. Belly: grayish brown. Underparts overall look blackish.

Wings: greenish olive and chestnut. Rump, tail, flanks and undertail: black.

Bill: long, stout and yellow-green. Legs and feet: red.

Males and females look alike, and juveniles are duller versions of the adults.

Behaviour and diet

This rail forages mostly at dawn and dusk. It is secretive, but in twilight it may step onto open mudflats and stream banks. Crabs are its main prey, along with other aquatic invertebrates.

Views can be short. On a Costa Rican mangrove outing, one birder heard the rail call, then watched it climb onto a branch and walk along it in clear view. Another group, on a boat trip through tall mangrove channels, got no response to their calls, and the one birder who saw a wood-rail managed only a brief digiscoped view as it showed on a branch.

Where it lives

In Costa Rica this rail mostly stays in mangroves. One was recorded in March 2012 in a red mangrove swamp at about 2 m elevation, along a slough feeding the Río Montaña at Nosara Biological Reserve, Guanacaste. It has also turned up at a few moist forest sites in the country.

Across much of its wider range it lives in mangroves and was long thought of as mainly coastal, but it also uses tropical dry forest and moist lowland forest. Elsewhere, inland records in humid and montane forest reach up to about 1,400 m.

Similar birds

The Russet-naped Wood-Rail is the one you are far more likely to see, and it is found across much of the country. It has a slate gray crown and hindneck, a chestnut patch on the back of the head, and a gray lower throat and upper breast, with a pale tawny cinnamon lower breast. The Rufous-necked is rufous on the whole head, neck and breast. The Gray-necked Wood-Rail (Rascón Cuelligrís) has a reddish chestnut chest, a black belly and pinkish legs.

Names and lore in Costa Rica

The Costa Rican Spanish name is Rascón Cuellirrufo. Other Spanish names listed for the species elsewhere are Cotara Cuellirrufa and Rascón Cuello Canela. The nicknames Chirincoco, Pomponé and Pone-pone belong to the Gray-necked Wood-Rail, not to this bird.

Status and conservation

The AOCR list marks it as a resident (R), a national checklist code calls it a rare resident, and Costa Rica treats it as endangered within the country.

Photography tips

Expect a short window. A group on a boat through tall mangrove channels got no answer to their calls, and the birder who saw one managed only a digiscoped view of it on a branch. Work at dawn or dusk, keep the camera ready and watch the branches above the mud.
