The willet (Tringa semipalmata) is a large shorebird in the family Scolopacidae. It is a relatively large and robust sandpiper and is the largest of the species called "shanks" in the genus Tringa.

It breeds in North America and the West Indies and winters in southern North America, Central America, the West Indies and South America.

He placed it in the genus Scolopax and coined the binomial name Scolopax semipalmata. Gmelin based his description on the "semipalmated snipe" from New York that had been described in 1785 by both the English ornithologist John Latham and by the Welsh naturalist Thomas Pennant. The willet was formerly assigned to the genus Catoptrophorus that had been introduced for the species in 1827 by Charles Lucien Bonaparte. In 2006 it was moved to the current genus Tringa based on a molecular... Wikipedia →

With luck
About 10% of wildlife watchers report a Willet sighting in Lima on a given day, based on 617 verified sightings from GBIF citizen-science data. It is the 66th most-seen of the 171 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Willet in Lima on a given day, against under 5% in January, the lowest month.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Willet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 23
Of the 23 cities where we can rate Willet sightings, Lima ranks 8th at about 10%. The best odds are in Panama City (Panama, about 30%), San Diego (United States, about 30%) and San Francisco (United States, about 20%).
Same genus: Tringa
The closest relatives of the Willet that you can see in Lima (genus Tringa, Shanks, Tattlers, and Allies) are Lesser Yellowlegs (about 10%) and Greater Yellowlegs (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Willet is recorded against all the birds logged in Lima (617 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.
