The American oystercatcher (Haematopus palliatus), occasionally called the American pied oystercatcher, is a member of family Haematopodidae. Originally called the "sea pie", it was renamed in 1731 when naturalist Mark Catesby claimed that he had observed the bird eating oysters. The current population of American oystercatchers is estimated to be 50,000 – 99,999 mature individuals. There are estimated to be 1,500 breeding pairs along the Atlantic and Gulf Coasts of the US. The bird is marked by its black and white body and a long, thick orange beak.
The American oystercatcher has distinctive black and white plumage and a long, bright orange beak. The head and breast are black and the back, wings and tail greyish-black. The underparts are white, as are feathers on the inner part of the wing which become visible during flight. The irises are yellow and the eyes have orange orbital rings. The legs are pink. Adults are between 42–52 cm (17–20 in) in length.
The American oystercatcher is found on the Atlantic coast of North America from coastal Massachusetts to northern Florida, where it is also found on the Gulf coast, the Caribbean, and south to Brazil... Wikipedia →

Possible
About 30% of wildlife watchers report an American Oystercatcher sighting in Lima on a given day, based on 1,897 verified sightings from GBIF citizen-science data. It is the 30th most-seen of the 171 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
February to October
In those months about 30% of wildlife watchers report an American Oystercatcher in Lima on a given day, against about 20% in November to January, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most American Oystercatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 10 cities where we can rate American Oystercatcher sightings, Lima has the highest daily chance: about 30%. Next come Vitória (Brazil, about 20%) and Montevideo (Uruguay, about 10%).
GBIF citizen-science records
It is estimated from how often the American Oystercatcher is recorded against all the birds logged in Lima (1,897 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.
