PLUNGE-DIVING
The Brown Pelican is
the only species of Pelican that uses a method of fishing called
"plunge-diving." They fly over the ocean at heights of 60 to 70 feet
and use their extremely sharp eyesight to spot schools of fish or
individual fish swimming in the water. Once their target is set,
they dive steeply into the water and scoop up their prey with their
pouch.
They may enter the water fully submerged or partly
depending on the height of the dive and what they are catching. The
Brown Pelican has air sacs beneath its skin to cushion the impact
of the dive and to help it reach the surface of the water.
The pelican’s pouch acts like a net and can hold
up to 3 gallons of water and three times as more than its stomach.
Once they have scooped up their prey the pelican holds the fish in
their pouch until all of the water has drained away. As they wait
for the water to drain and devour their tasty snack, hungry sea gulls
will hover above the pelicans or even sit on their bills, ready to
steal a wayward fish.
Once the water has drained away the pelican
will swallow the fish and carry them in its esophagus. Along with
being a great fishing tool, the pelican’s pouch also acts as
a cooling unit in hot weather and as a feeding station for young
pelicans.
WEATHERING THE STORM
What exactly do pelicans do during a hurricane? According to experts
at the Pelican Harbor
Seabird Station they are great at preparing
for a storm. As it approaches the pelicans will sit on the ground
and they point their chest to the wind and put their head on their
back. Then they will cover their eyes with their wings and ride it
out like the rest of us. There have even been some sightings of pelicans
flying around in a category one hurricane.
