the i sh. Cormorants dive into water and swim
using their wings and feet. They catch i sh with
their hooked beaks and can reach depths of
40 m (Dugan 2005). People have long used cor-
morants as traditional i shing aids, and cormo-
rant i shing is still practiced in parts of Japan,
China, and Macedonia. Like the anhinga, cormo-
rant feathers are wettable, which allows them
to swim deeply, so they must dry their feathers
frequently.
Many raptors exploit the aquatic environ-
ment to catch i sh, amphibians, rodents, snakes,
crayi sh, and other small animals. Several raptors
are adapted for this lifestyle, including the
northern harrier (
Circus cyaneus
), osprey
(
Pandion haliaetus
), red-shouldered hawk
(
Buteo lineatus
), and African i sh eagle (see Fig.
