The russet-naped wood rail or rufous-naped wood rail (Aramides albiventris) is a species of bird in the subfamily Rallinae of the rail, crake, and coot family Rallidae. It is found from Mexico to Costa Rica. The russet-naped wood rail was originally described as a species but in the early 20th century was reclassified as a subspecies of what was then called the gray-necked wood rail (Aramides cajanea). A 2015 paper by Marcondes and Silveira proposed reconsidering its position and in 2016 taxonomic systems restored it to species status and renamed the now-reduced A. cajanea the grey-cowled wood rail.
The Clements taxonomy and BirdLife International's Handbook of the Birds of the World follow Marcondes and Silveira in treating the russet-naped wood rail as monotypic. However, the International Ornithological Committee (IOC) assigns it these five subspecies:

With luck
About 10% of wildlife watchers report a Russet-naped Wood-Rail sighting in Calakmul Biosphere Reserve on a given day, based on 138 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 107th most-seen of the 271 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Russet-naped Wood-Rail in Calakmul Biosphere Reserve on a given day, against under 5% in April and May, the lowest months. That is one of Calakmul Biosphere Reserve's driest months, with about 30 mm of rain against 130 mm in June.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Russet-naped 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 17
Of the 17 parks where we can rate Russet-naped Wood-Rail sightings, Calakmul Biosphere Reserve ranks 4th at about 10%. The best odds are in Tikal National Park (Guatemala, about 50%), Tortuguero National Park (Costa Rica, about 20%) and Sian Ka'an Biosphere Reserve (Mexico, about 20%).
GBIF citizen-science records
It is estimated from how often the Russet-naped Wood-Rail is recorded against all the birds logged in Calakmul Biosphere Reserve (138 verified sightings from 2019 to 2026), 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.
