The Brown Pelican found along our coastline
is the smallest of the world's eight pelican
species. It averages four feet tall with a
wingspan of up to seven and a half feet, not
exactly lilliputian by any standard! The Brown
Pelican also distinguishes itself from other
pelicans because of its method of feeding, which
is by diving. All other pelicans feed from the
surface. It's a sight to behold; watching these
gangly looking birds dive bomb directly down
from heights as great as 75 feet to feed exclusively
on marine fish.
The Brown Pelican is the politically
correct bird for the 90's because unlike many
of its feathered brethren, both females and males
alike have identical coloration. Adults have a white
head and neck, brown grey body and wings with
a black belly. Juveniles tend to be mostly
brown except for a white belly and some white
at the base of the neck.
The famous pouch, attached to the bottom
part of the pelican's bill, lacks feathers.
People in the know believe this keeps the bird
cool. Also, the pelican uses the pouch only to
catch its meals; not to store them as some
people believe.
Breeding along our coastline occurs on the
Channel Islands off the coast of Santa Barbara
where the pelican nests on the ground. The
nestlings are fed freshly caught fish
regurgitated by the parents onto the nest floor.
As the nestlings mature, they are fed
regurgitated meals directly from the parents'
pouch. These feather-poor babies often sqawk
up a storm, possibly sensing it's their last
chance.
As adults, the Brown Pelican is the Marcel
Marceau of the bird world, never uttering a
sound, although it does possess an elaborate
display repertoire.
The Brown Pelican can be found from the
Canadian border to South America on the West
Coast and from North Carolina to the West
Indies on the East Coast, including the entire
Gulf of Mexico region.
This incredible bird we now take for granted
was not always so plentiful. Only 25 years
ago these pelicans were not hatching any young.
With their populations dipping to near extinction
levels, they were placed in protected status.
After careful study it was found that the pelicans
had alarmingly high levels of a pesticide called
DDT in their systems.
The DDT had made its way down river to the
oceans as runoff from agricultural areas and
had worked itself up through the marine chain,
and finally into the pelicans through the fish
consumed. The DDT was blocking sufficient calcium
formation so completely that the eggs were far
too fragile to be incubated; i.e. smashed eggs!
Fortunately for us, the banning of DDT in 1972
has helped to allow the pelicans to have year after
year of successful births, bringing back the
population numbers to acceptable levels.
In a way, the pelicans acted as a barometer
of the environment to show us humans just how
badly we were affecting the world by our
shortsighted application of pesticides. What a
pity it would have been for us at Doheny and
everyone else on both coasts if we couldn't marvel
at these stately birds flying in that classic
"V" formation on a layer of air jsut inches from
the water, defying the swells to alter their course.
