The mangrove rail (Rallus longirostris) is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Central and South America. The mangrove rail was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1781 in his Histoire Naturelle des Oiseaux from a specimen obtained in French Guiana. The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Rallus longirostris in his catalogue of the Planches Enluminées. The genus Rallus had been erected in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. The specific epithet longirostris combines the Latin longus meaning "long" and -rostris meaning "-billed".
The mangrove rail was formerly considered to be conspecific with what are now the Aztec rail (R. tenuirostris), Ridgway's rail... Wikipedia →

Rare
Under 5% of wildlife watchers report a Mangrove Rail sighting in Palo Verde National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 194th most-seen of the 274 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Mangrove Rail in Palo Verde National Park on a given day, against under 5% in June to April, the lowest months. That is one of Palo Verde National Park's wettest months, with about 280 mm of rain against almost none in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Mangrove 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.
Among the best
Of the 2 parks where we can rate Mangrove Rail sightings, Palo Verde National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Caroni Swamp (Trinidad and Tobago, under 5%).
Same family: Rallidae
The closest relatives of the Mangrove Rail that you can see in Palo Verde National Park (family Rallidae, Rails, Gallinules, and Coots) are American Purple Gallinule (about 40%), Common Moorhen (about 10%) and Sora (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Mangrove Rail is recorded against all the birds logged in Palo Verde National Park (22 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.
