Mallard Anas platyrhynchos
Mallard is a beautiful sexually dimorphic duck. The male is distinguished with its glossy green head, grey wings and yellow bill; whilst the female has a conspicuous brown-speckled plumage.
This dabbling duck prefers calm, shallow sanctuaries and breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It lays eight to thirteen creamy white to greenish-buff spotless eggs; once hatched, ducklings are precocial and fully capable of swimming as soon as they hatch.
Although Mallard ducks are least concerned on the IUCN Red List, however, a cogent threat to its population is hybridization with other ducks and outbreeding depression.
