About These Birds
Southern Pintail
A small island duck found on the remote Kerguelen and Crozet archipelagos in the sub-Antarctic Indian Ocean. Closely related to Northern Pintail. Non-migratory island endemic; small population threatened by introduced predators and overgrazing by rabbits.
Mallard
The mallard is the ancestor of most domestic duck breeds and the most abundant and widespread dabbling duck in the world. Males perform elaborate courtship displays including head-bobbing and whistle-grunt calls. Mallards are highly adaptable, thriving in both wilderness and urban environments.
