|Bowl-shaped, built on water in dense emergent vegetation
with sedges and woody plants.
Omnivores and feed mainly by diving or dabbling at the
surface. Ducklings are dependent on animal matter such
as insects earth worms, leeches, midges and snails. As they
mature they tend change their diet to submerged plants.
The adult male is similar in color pattern to the Eurasian tufted duck,
its relative. Males are a little bit bigger than the female. It has two
white rings surrounding its gray bill, a shiny black angular head,
black back, white line on the wings, a white breast and yellow eyes.
The adult female has a grayish brown angular head and body with a dark
brown back, a dark bill with a more subtle light band than the male,
grayish-blue feet and brown eyes with white rings surrounding them. The
cinnamon neck ring is usually difficult to observe, which is why the
bird is sometimes referred to as a "ringbill".
Their breeding habitat is wooded lakes or ponds in the
United States and Canada. The main breeding
area is Northwest
boreal forest territories. Ring-necked duck
pairs start during spring migration. Unpaired ducks showing up on
breeding grounds will most likely end up being non-breeders. The pairs
stay together only for reproduction, then, they separate.
One per day until 8 - 10 are laid.
