The oriental pratincole (Glareola maldivarum), also known as the grasshopper-bird or swallow-plover, is a wader in the pratincole family, Glareolidae. The genus name is a diminutive of Latin glarea, "gravel", referring to a typical nesting habitat for pratincoles. The species name, maldivarum, refers to the type locality, the ocean near the Maldive Islands. The type specimen, caught alive at sea, survived for a month on flies.
The Oriental pratincole has short legs, long pointed wings and long forked tails. It has a short bill, which is an adaptation to aerial feeding. The back and head are brown, and the wings are brown with black flight feathers. The belly is white and the underwings are chestnut.
Very good views are needed to distinguish the species from other pratincoles, particularly the very similar collared pratincole, which also has a chestnut underwing. The black-winged pratincole shares the black upperwing flight feathers, and lacks a white trailing edge to the wing. Those features are not always readily seen in the field, especially because the chestnut underwing appears black unless excellent views are obtained.

Rare
Under 5% of wildlife watchers report an Oriental Pratincole sighting in Tokyo on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 165th most-seen of the 229 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 an Oriental Pratincole in Tokyo 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 Oriental Pratincole sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
12th of 13
Of the 13 cities where we can rate Oriental Pratincole sightings, Tokyo ranks 12th at under 5%. The best odds are in Phnom Penh (Cambodia, about 10%), Bangkok (Thailand, under 5%) and Tainan (Taiwan, under 5%).
Same order: Charadriiformes
The closest relatives of the Oriental Pratincole that you can see in Tokyo (order Charadriiformes, Shorebirds and Allies) are Common Sandpiper (about 20%), Black-headed Gull (about 20%) and Black-tailed Gull (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oriental Pratincole is recorded against all the birds logged in Tokyo (41 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.
