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...

Rare
Under 5% of wildlife watchers report a Dunlin sighting in Monfragüe National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 198th most-seen of the 205 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Dunlin in Monfragüe National Park on a given day, so our monthly data shows no clear season.
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.
32nd of 32
Of the 32 parks where we can rate Dunlin sightings, Monfragüe National Park ranks 32nd at under 5%. The best odds are in Wadden Sea National Park (Germany, about 40%), Doñana National Park (Spain, about 30%) and Kiskunság National Park (Hungary, about 20%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Dunlin is recorded against all the birds logged in Monfragüe National Park (7 verified sightings from 2019 to 2026), 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.
