The clapper rail (Rallus crepitans) is a member of the rail family, Rallidae. The taxonomy for this species is confusing and still being determined.

This species was formerly considered to be conspecific with the mangrove rail.
The clapper rail was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other rails in the genus Rallus and coined the binomial name Rallus crepitans. Gmelin based his description on those by Thomas Pennant and John Latham. The type locality is Long Island, New York. 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 crepitans is Latin meaning "breaking wind" or "resounding".
The clapper rail was formerly treated as a subspecies of the mangrove rail (Rallus longirostris). The decision to treat the clapper rail as a separate species was based on the results of a molecular phylogenetic... Wikipedia →

Rare
Under 5% of wildlife watchers report a Clapper Rail sighting in New York City on a given day, based on 2,787 verified sightings from GBIF citizen-science data. It is the 169th most-seen of the 359 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report a Clapper Rail in New York City on a given day, against under 5% in September to May, the lowest months.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Clapper Rail sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Clapper Rail sightings, New York City has the highest daily chance: under 5%. Next come Boston (United States, under 5%) and Miami (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Clapper Rail is recorded against all the birds logged in New York City (2,787 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.
