Hooded Mergansers

Description:

Last year I started actively birding and spotted these beautiful winter migrants in the Waterfowl Pond in the San Francisco Botanical Garden.

Habitat:

Waterfowl Pond in the San Francisco Botanical Garden, CA.

Notes:

The Hooded Merganser (Lophodytes cucullatus) is a small duck and is the only member of the genus Lophodytes. Hooded Mergansers have a crest at the back of the head which can be expanded or contracted. In adult males, this crest has a large white patch, the head is black and the sides of the duck are reddish-brown. The adult female has a reddish crest, with much of the rest of the head and body a greyish-brown. The Hooded Merganser has a sawbill but is not classified as a typical merganser. Hooded Mergansers are the second smallest species of merganser, with only the Smew of Europe and Asia being smaller, and is also the only Merganser whose native habitat is restricted to North America. Their preferred habitat for breeding is in swamps and wooded ponds of the northern half of the United States and southern Canada. They prefer to nest in tree cavities near water, but will use Wood Duck nesting boxes if available and unoccupied. They form pairs in early winter. The male leaves the female soon after she lays her eggs, leaving her responsible for all incubation. After hatching, chicks leave the nest with their mother within 24 hours; they are already able to dive and feed themselves, although they remain with their mother for another five weeks. Wikipedia
