Ruddy Turnstone

Q: What are the chances of seeing a Ruddy Turnstone in Boston?

Rare. Under 5% of wildlife watchers report a Ruddy Turnstone sighting in Boston on a given day, based on 533 verified sightings from GBIF citizen-science data. It is the 161st most-seen of the 283 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.

Q: When is the best time to see a Ruddy Turnstone in Boston?

Any time of year. In every month with enough records, under 5% of wildlife watchers report a Ruddy Turnstone in Boston on a given day, so our monthly data shows no clear season.

Q: What time of day is best to see a Ruddy Turnstone?

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.

Q: Is Boston the best place to see a Ruddy Turnstone?

40th of 68. Of the 68 cities where we can rate Ruddy Turnstone sightings, Boston ranks 40th at under 5%. The best odds are in Casablanca (Morocco, about 40%), São Luís (Brazil, about 20%) and Maputo (Mozambique, about 20%).

Q: Where does the Ruddy Turnstone sighting chance come from?

GBIF citizen-science records. It is estimated from how often the Ruddy Turnstone is recorded against all the birds logged in Boston (533 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.

About the Ruddy Turnstone

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"...
