Northern Shoveler(Anas clypeata) The
colorful male Northern Shoveler is distinctive and in the air shows a lot of
white on the body. It is one of the
most common ducks that visit the Los Peñasquitos Lagoon during the winter.
It swims with its head low and uses its huge spatula-like bill to strain
out food. Shovelers commonly feed
in small groups that mill around in a circle and churn up the mud.
Since their food is strained from near the surface, they seldom have to
“tip up”. An enormous
development of the comblike teeth along the sides of the mandibles
makes this whalelike manner of feeding possible. |
