About These Birds
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.
Puna Teal
A medium-sized pale grey teal with a distinctive blue-grey bill, dark cap, and black-and-white back pattern. Restricted to high Andean wetlands. Found in large flocks on puna lakes and salars. Closely related to Silver Teal; sometimes treated as conspecific.
