The red-necked stint or rufous-necked stint (Calidris ruficollis) is a small migratory wader that breeds in northeast Russia and spends the non-breeding season along the coastlines of Southeast Asia and Australasia. The red-necked stint was formally described in 1776 by the German naturalist Peter Simon Pallas under the binomial name Trynga ruficollis. The specific epithet ruficollis is Modern Latin meaning "red-necked" from Latin rufus meaning "red" or "rufous" and -collis meaning "-necked" or "-throated". The type locality is southern Transbaikal in eastern Siberia. The red-necked stint is now placed with 23 other species in the genus Calidris that was introduced in 1804 by the German naturalist Blasius Merrem. The species is monotypic, with no subspecies recognised. Within the genus Calidris the red-necked stint is most closely related to the spoon-billed sandpiper (Calidris pygmaea).
These birds are among the smallest of waders, very similar to the little stint, Calidris minuta, with which they were once considered conspecific. The red-necked stint's small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders... Wikipedia →

Rare
Under 5% of wildlife watchers report a Red-necked Stint sighting in Tokyo on a given day, based on 536 verified sightings from GBIF citizen-science data. It is the 87th most-seen of the 229 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 20% of wildlife watchers report a Red-necked Stint in Tokyo on a given day, against under 5% in June–August and November–April, the lowest months. That is one of Tokyo's wettest months, with about 210 mm of rain against 75 mm in February.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Red-necked Stint 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 24
Of the 24 cities where we can rate Red-necked Stint sightings, Tokyo ranks 7th at under 5%. The best odds are in Quanzhou (China, about 20%), Makassar (Indonesia, about 10%) and Davao City (Philippines, about 10%).
GBIF citizen-science records
It is estimated from how often the Red-necked Stint is recorded against all the birds logged in Tokyo (536 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.
