PELICANS
Pelicans are large water birds famous for their long bills and huge throat pouches. Belonging to the family Pelecanidae, these birds are found on every continent except Antarctica. They inhabit lakes, rivers, estuaries, wetlands, and coastal regions, where fish are plentiful.
With their impressive size and graceful flight, pelicans are among the most recognisable birds in the world. They have adapted perfectly to life near water and are considered some of nature's most skilled fishermen.
PHYSICAL FEATURES
Pelicans are among the largest flying birds. Depending on the species, they can measure 1.2 to 1.8 metres in length and have a wingspan ranging from 2 to over 3.5 metres. Some species weigh as much as 15 kilograms.
Their most distinctive feature is their long bill fitted with a flexible throat pouch called a gular pouch. Contrary to popular belief, this pouch is not used to store food for long periods. Instead, it acts like a fishing net, helping the bird scoop up fish and drain excess water before swallowing its catch.
Their large wings allow them to soar effortlessly for long distances, using rising warm air currents to conserve energy.
DIFFERENT SPECIES
There are eight living species of pelicans found around the world. Some of the best-known species include:
●Great White Pelican
●Brown Pelican
●Spot-billed Pelican
●Dalmatian Pelican
●Australian Pelican
●Pink-backed Pelican
●American White Pelican
●Peruvian Pelican
India is home to the Spot-billed Pelican, which breeds in several protected wetlands in southern India.
HABITAT
Pelicans prefer habitats with abundant fish, such as:
●Freshwater lakes
●Rivers
●Marshes
●Mangrove forests
●Coastal lagoons
●Seashores
They often gather in large colonies, where hundreds or even thousands of birds live and breed together.
WHAT DO PELICANS EAT?
Pelicans mainly feed on fish, although they may also eat frogs, crustaceans, and occasionally small reptiles.
Their hunting techniques vary according to the species.
Some pelicans simply swim and scoop fish into their pouches.
The Brown Pelican is famous for its spectacular plunge-diving. It flies high above the water and suddenly dives headfirst, hitting the surface with tremendous force to catch fish beneath.
Other pelicans hunt cooperatively. A group forms a semicircle and beats the water with their wings, driving fish into shallow water where they can be caught more easily.
AMAZING FLIGHT
Despite their large size, pelicans are excellent fliers. They soar gracefully using warm air currents called thermals and can travel hundreds of kilometres during migration.
When flying in groups, pelicans often form V-shaped formations, reducing air resistance and saving energy.
BREEDING AND FAMILY LIFE
Pelicans are highly social birds. During the breeding season, they nest in large colonies on islands, lakeshores, or wetlands.
The female usually lays one to three eggs. Both parents share the responsibility of incubating the eggs and feeding the chicks.
Young pelicans hatch naked and helpless. Their parents feed them by regurgitating partially digested fish. As they grow, the chicks become strong swimmers and eventually learn to fly.
ECOLOGICAL IMPORTANCE
Pelicans help maintain healthy fish populations and serve as indicators of healthy aquatic ecosystems. Since they depend on clean water and abundant fish, their presence often reflects a well-balanced environment.
THREATS TO PELICANS
Although many pelican species remain widespread, several face serious challenges, including:
●Wetland destruction
●Water pollution
●Plastic waste
●Overfishing
●Climate change
●Disturbance at nesting sites
Conservation efforts, including wetland protection and wildlife sanctuaries, are helping many pelican populations recover.
DID YOU KNOW?
●The Australian Pelican has one of the longest bills of any living bird, measuring up to 50 centimetres.
●Pelicans can hold over 10 litres of water in their throat pouch before draining it out.
●Their wingspan can exceed 3.5 metres, making them among the largest flying birds.
●Pelicans have air sacs beneath their skin and inside their bones, making them lighter and helping cushion their plunge dives.
●A pelican's pouch stretches like an elastic bag but is never used as a permanent food storage bag.
FASCINATING FACTS
●Expert Teamwork
Many pelicans cooperate while hunting, surrounding schools of fish and herding them into shallow water before scooping them up.
●Built for Soaring
Pelicans can fly at heights of over 3,000 metres, travelling long distances with very little wing flapping.
●Nature's Fishing Net
A pelican's pouch can hold several times more than its stomach can. After catching fish, the bird tips its head forward to drain the water before swallowing its meal.
●Ancient Birds
Pelican ancestors lived over 30 million years ago, making them one of the oldest groups of modern water birds.
●Gentle Giants
Despite their large size and impressive appearance, pelicans are generally peaceful birds that prefer cooperation over aggression.
●Pelicans in India
India's wetlands provide an ideal habitat for the Spot-billed Pelican, especially in the southern states. Protected areas such as the Kokrebellur Bird Sanctuary in Karnataka, the Vedanthangal Bird Sanctuary in Tamil Nadu, and several wetlands in Andhra Pradesh support important breeding colonies.
●These birds play an important role in wetland ecosystems and are admired by birdwatchers and nature enthusiasts.
CONCLUSION
Pelicans are magnificent birds that combine strength, grace, and intelligence. Their remarkable fishing techniques, impressive wingspans, and cooperative behaviour make them one of the most fascinating birds on Earth. Protecting wetlands and keeping our water bodies clean will ensure that future generations continue to witness these gentle giants soaring across the skies and gliding gracefully over lakes and oceans.
