The ruddy turnstone (Arenaria interpres) is a small cosmopolitan wading bird, one of two species of turnstone in the genus Arenaria. It is now classified in the sandpiper family Scolopacidae but was formerly sometimes placed in the plover family Charadriidae. It is a highly migratory bird, breeding in northern parts of Eurasia and North America, and flying south to winter on coastlines almost worldwide. It is the only species of turnstone in much of its range and is often known simply as turnstone.
The ruddy turnstone was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tringa interpres. The species is now placed together with the black turnstone in the genus Arenaria that was introduced by the French zoologist Mathurin Jacques Brisson in 1760 with the ruddy turnstone as the type species. The genus name arenaria is from Latin arenarius, "inhabiting sand", from arena, "sand". The specific interpres means "messenger"; when visiting Gotland in 1741, Linnaeus thought that the Swedish word Tolk, meaning "interpreter" applied to this species, but in the local dialect the word means "legs"...

Possible
About 20% of wildlife watchers report a Ruddy Turnstone sighting in Liverpool on a given day, based on 788 verified sightings from GBIF citizen-science data. It is the 55th most-seen of the 168 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March and April
In those months about 40% of wildlife watchers report a Ruddy Turnstone in Liverpool on a given day, against about 10% in June–July and September, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Ruddy Turnstone 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 68
Of the 68 cities where we can rate Ruddy Turnstone sightings, Liverpool ranks 4th at about 20%. The best odds are in Casablanca (Morocco, about 40%), São Luís (Brazil, about 20%) and Maputo (Mozambique, about 20%).
Same family: Scolopacidae
The closest relatives of the Ruddy Turnstone that you can see in Liverpool (family Scolopacidae, Sandpipers and Allies) are Common Redshank (about 50%), Bar-tailed Godwit (about 40%) and Dunlin (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ruddy Turnstone is recorded against all the birds logged in Liverpool (788 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.
