The dunlin (Calidris alpina) is a small wader in the genus Calidris. The English name is a dialect form of "dunling", first recorded in 1531–1532. It derives from dun, "dull brown", with the suffix -ling, meaning a person or thing with the given quality.
It is a circumpolar breeder in Arctic or subarctic regions. Birds that breed in western Europe are short-distance migrants largely staying on western and southern European and northwest African coasts; those breeding in far northern Europe and Asia are long-distance migrants, wintering south to Africa, southeast and west Asia. Birds that breed in Alaska and the Canadian Arctic migrate short distances to the Pacific and Atlantic coasts of North America, although those nesting in northern Alaska overwinter in Asia.
The dunlin was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tringa alpina. Linnaeus specified the location as Lapland. This species was formerly placed (with the other "stints") by some American authors in the genus Erolia, but is now placed with 23 other sandpipers in the genus Calidris that was introduced in 1804 by the...

Possible
About 20% of wildlife watchers report a Dunlin sighting in Quanzhou on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 52nd most-seen of the 85 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Dunlin in Quanzhou on a given day, against about 10% in April–May, July, September and November, the lowest months. That is one of Quanzhou's driest months, with about 60 mm of rain against 240 mm in June. June, August and October have too few records to rate.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Dunlin 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 63
Of the 63 cities where we can rate Dunlin sightings, Quanzhou ranks 4th at about 20%. The best odds are in Liverpool (United Kingdom, about 40%), Kuwait City (Kuwait, about 30%) and Manama (Bahrain, about 30%).
Same genus: Calidris
The closest relatives of the Dunlin that you can see in Quanzhou (genus Calidris, Calidris Sandpipers) are Red-necked Stint (about 20%), Long-toed Stint (about 20%) and Curlew Sandpiper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dunlin is recorded against all the birds logged in Quanzhou (13 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.
