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 specific name of Linnaeus is thus onomatopoetic, the "duck that says cryc"; the common names in Norwegian krikkand, Danish krikand, and German Krickente mean the same, referring to the male's characteristic call which was already discussed by Linnaeus' sources.

Description

The Eurasian teal is one of the smallest extant dabbling ducks at length and with an average weight of in drake (males) and in hens (females). The wings are long, yielding a wingspan of . The bill measures in length, and the tarsus .
This is a noisy species. The male whistles cryc or creelycc, not loud but very clear and far-carrying. The female has a feeble keh or neeh quack.
Altogether, the Eurasian teal is much less common than its American counterpart, though still very plentiful. Its numbers are mainly assessed by counts of wintering birds; some 750,000 are recorded annually around the Mediterranean and Black Seas, 250,000 in temperate western Europe, and more than 110,000 in Japan. In 1990 and 1991, a more detailed census was undertaken, yielding over 287,000 birds wintering in Iran, some 109,000 in Pakistan, some 37,000 in India, 28,000 in Israel, over 14,000 in Turkmenistan and almost 12,000 in Taiwan. It appears to be holding its own currently, with its slow decline of maybe 1–2% annually in the 1990s, presumably mainly due to drainage and pollution of wetlands, not warranting action other than continuing to monitor the population and possibly providing better protection for habitat on the wintering grounds. The IUCN and BirdLife International classify the Eurasian teal as a species of Least Concern, unchanged from their assessment before the split of the more numerous A. carolinensis.
