The Eurasian oystercatcher or European oystercatcher (Haematopus ostralegus), also known as the common pied oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It has striking black and white plumage, a long straight orange-red bill, red eyes and relatively short dull pink legs. The sexes are similar in appearance but the bill of the female is longer than that of the male.
It is the most widespread of the oystercatchers, with four subspecies breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. The Eurasian oystercatcher was listed by Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae under the binomial name Haemotopus ostralegus. The genus name Haematopus combines the Ancient Greek haima αἷμα meaning "blood" and pous πούς meaning "foot". The specific epithet ostralegus combines the Latin ostrea meaning "oyster" and legere meaning "to gather".
The name "oyster catcher" was coined by Mark Catesby in 1731 as a common name for the North American species H. palliatus, described as eating oysters... Wikipedia →

Rare
Under 5% of wildlife watchers report a European Oystercatcher sighting in Copenhagen on a given day, based on 102 verified sightings from GBIF citizen-science data. It is the 73rd most-seen of the 154 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March to June
In those months about 10% of wildlife watchers report a European Oystercatcher in Copenhagen on a given day, against under 5% in July to February, the lowest months.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most European Oystercatcher sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
17th of 38
Of the 38 cities where we can rate European Oystercatcher sightings, Copenhagen ranks 17th at under 5%. The best odds are in Liverpool (United Kingdom, about 50%), Dublin (Ireland, about 40%) and Helsinki (Finland, about 30%).
Same order: Charadriiformes
The closest relatives of the European Oystercatcher that you can see in Copenhagen (order Charadriiformes, Shorebirds and Allies) are Black-headed Gull (about 70%), European Herring Gull (about 60%) and Common Gull (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the European Oystercatcher is recorded against all the birds logged in Copenhagen (102 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.
