Similar Species
Female somewhat similar to a small female Garganey or Blue-winged Teal, most easily distinguishable by pale line under the tail edge and smaller bill.
Distribution
Widespread throughout Eurasia, Africa (except the south), North and Central America
Taxonomy
Subspecies
Two to three subspecies are accepted:1
- A. c. crecca — Common Teal
- A. c. nimia (included in A. c. crecca by some authors)
- Aleutian Islands
- Very similar to A. c. crecca; differs in marginally larger average size.
- A. c. carolinensis — Green-winged Teal
- North America; winters to Mexico and West Indies
- Widely recognised as a separate species, A. carolinensis2; taxonomy still in much of debate as genetically, this subspecies seems to be more closely related to Andean Teal and Yellow-billed Teal than to nominate A. c. crecca.
Habitat
Freshwater wetlands, reedbeds, small lakes and ponds.
Behaviour
Flight
Explosive vertical take-off when startled.
Diet
Their diet is varied and includes insects, larvae, worms, molluscs and crustaceans and vegetation including seeds.
Breeding
It is a ground nester, nesting in a hollow lined with leaves and down feathers, near water. The 8-11 eggs are incubated for 21-23 days. The young fledge 25-30 days later.
Vocalisation
Call: male, a clear, far-reaching, whistle; female a "krik" sound.
