The spotless crake (Zapornia tabuensis) is a species of bird in the rail family, Rallidae. It is widely distributed species occurring from the Philippines, New Guinea, Australia, New Zealand across the southern Pacific Ocean to the Marquesas Islands to the south east along the Tuamotus island chain to Pitcairn Oeno island.
The spotless crake 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 the other crakes and rails in the genus Rallus and coined the binomial name Rallus tabuensis. Gmelin's account is taken from that of the "Tabuan rail" that had been described in 1785 by the English ornithologist John Latham in his book A General Synopsis of Birds. Latham's description was probably based on a plate painted by the German naturalist Georg Forster who had accompanied the British explorer James Cook on his second voyage to the Pacific Ocean. The genus name is an anagram of the genus Porzana that was introduced by the French ornithologist Louis-Pierre Vieillot. The specific epithet tabuensis is from Tongatapu, Tonga, the type locality.

Rare
Under 5% of wildlife watchers report a Sooty Rail sighting in Perth on a given day, based on 140 verified sightings from GBIF citizen-science data. It is the 98th most-seen of the 162 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Sooty Rail in Perth on a given day, so our monthly data shows no clear season.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Sooty 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.
4th of 5
Of the 5 cities where we can rate Sooty Rail sightings, Perth ranks 4th at under 5%. The best odds are in Brisbane (Australia, about 10%), Melbourne (Australia, under 5%) and Auckland (New Zealand, under 5%).
GBIF citizen-science records
It is estimated from how often the Sooty Rail is recorded against all the birds logged in Perth (140 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.
