American White Pelican
The American White Pelican (Pelecanus erythrorhynchos) is a very large
bird. Which grows up to 50-70 inches; this is a white bird with black
wing tips and a massive orange bill. They have a wingspan of approximately
3 m. their flight is considered to be graceful, moving their wings in
slow controlling strokes.
The Brown Pelican usually dives for its food; but the American White
Pelican does not follow this act. The white pelican follows something
called the cooperative fishing. Each bird eats more than 4 pounds of fish
a day, mostly carp, chubs, shiners, perch, catfish, and jackfish.
White Pelicans live in islands and they nest in colonies of several hundred
pairs. They mostly live on islands of remote brackish and freshwater lakes
of inland North America. The female bird lays its eggs in the ground itself
wherever it finds a shallow depression. Both the parent birds incubate.
Nowadays white pelicans are becoming extinct because of the shooting
by the poachers and this is the cause of mortality. These birds are very
sensitive to human inhabitation and thus they will abandon their nests
if human presence is identified.Migratory Bird Treaty of 1972 protects
these species.
This bird’s scientific name is derived from Latin and Greek, the
name this species combines Pelecanus, the Latin for pelican, with erythrorhynchos,
derived from the Greek words erythros meaning red, and rhynchos meaning
beak.
