Like geese, cormorants
migrate in large arcs or in wedge-shaped flocks, but are silent when flying.
The
word "cormorant" is derived, through French, from the Latin corvus marinus, or
"sea crow."
A solidly built black
cormorant with orange throat pouch and long neck. Long hooked bill tilted upward
when bird swims.
Adults have short tuft of
feathers over each eye during breeding season.
Young birds are browner,
whitish or buffy on breast, upper belly, and neck.
In flight, the neck shows
a slight crook, not seen in the similar Brandt's Cormorant, the larger Great
Cormorant, or the smaller Neotropic.
