The semipalmated plover (Charadrius semipalmatus) is a small plover. Charadrius is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek kharadrios a bird found in ravines and river valleys (kharadra, "ravine"). The specific semipalmatus is Latin and comes from semi, "half" and palma, "palm". Like the English name, this refers to its only partially webbed feet.
This species weighs a mean 47.4 g (1.7 oz.) for males and 46.1 g (1.6 oz.) for females, with body masses ranging from 37.6-54.7 g (1.3-1.9 oz.). and measures 17–19 cm (6.7–7.5 in) in length with a 12–13 cm (4.7–5.1 in) mean wing length. Adults have a grey-brown back and wings, a white belly, and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes and a short orange and black bill.
Their breeding habitat is open ground on beaches or flats across northern Canada and Alaska. They nest on the ground in an open area with little or no plant growth. They are migratory and winter in coastal areas of the southern United States, the Caribbean and much of South America. They are extremely rare... Wikipedia →

With luck
About 10% of wildlife watchers report a Semipalmated Plover sighting in Vitória on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 60th most-seen of the 126 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.
November
In that month about 20% of wildlife watchers report a Semipalmated Plover in Vitória on a given day, against under 5% in August and September, the lowest months. That is one of Vitória's wettest months, with about 200 mm of rain against 45 mm in July.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Semipalmated Plover sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 37
Of the 37 cities where we can rate Semipalmated Plover sightings, Vitória ranks 7th at about 10%. The best odds are in São Luís (Brazil, about 40%), Havana (Cuba, about 20%) and Panama City (Panama, about 10%).
GBIF citizen-science records
It is estimated from how often the Semipalmated Plover is recorded against all the birds logged in Vitória (53 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.
