The Eurasian teal (Anas crecca), common teal, or Eurasian green-winged teal is a common and widespread duck that breeds in temperate Eurosiberia and migrates south in winter. The Eurasian teal is often called simply the teal due to being the only one of these small dabbling ducks in much of its range. The bird gives its name to the blue-green colour teal.
It is a highly gregarious duck outside the breeding season and can form large flocks. It is commonly found in sheltered wetlands and feeds on seeds and aquatic invertebrates. The North American green-winged teal (A. carolinensis) was formerly (and sometimes is still) considered a subspecies of A. crecca.
The Eurasian teal belongs to the "true" teals, a group of small Anas dabbling ducks closely related to the mallard (A. platyrhynchos) and its relatives; that latter group in fact seems to have evolved from a true teal. It forms a superspecies with the green-winged teal and the speckled teal (A. flavirostris). A formerly proposed subspecies, A. c. nimia, from the Aleutian Islands, differs only in slightly larger size; it is no longer considered distinct.

Possible
About 30% of wildlife watchers report a Eurasian Teal sighting in Tokyo on a given day, based on 7,315 verified sightings from GBIF citizen-science data. It is the 21st most-seen of the 229 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
December
In that month about 50% of wildlife watchers report a Eurasian Teal in Tokyo on a given day, against under 5% in June to August, the lowest months. That is one of Tokyo's driest months, with about 85 mm of rain against 250 mm in October.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Eurasian Teal sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
8th of 115
Of the 115 cities where we can rate Eurasian Teal sightings, Tokyo ranks 8th at about 30%. The best odds are in Sendai (Japan, about 50%), Nagoya (Japan, about 40%) and Naha (Japan, about 40%).
Same genus: Anas
The closest relatives of the Eurasian Teal that you can see in Tokyo (genus Anas, Mallards, Pintails, and Allies) are Eastern Spot-billed Duck (about 70%), Mallard (about 30%) and Northern Pintail (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eurasian Teal is recorded against all the birds logged in Tokyo (7,315 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.
