How does a pelican catch fish?
Many pelicans fish by swimming in cooperative groups. Pelicans do not store fish in their pouch, but simply use it to catch them and then tip it back to drain out water and swallow the fish immediately. The American white pelican can hold some 3 gallons of water in its bill.
What does a pelican use to catch its prey?
In reality, pelicans use their gular pouches as a means of capturing food—not as a place to keep it tucked away for extended periods. The highly-flexible sacs can expand or contract, and the lower jaw bones they’re connected to are capable of bowing outwards, which enables the birds to use their sacs as fishing nets.
How do pelicans eat whole fish?
Pelicans eat fish from the ocean. Small to medium sized fish. These fish are eaten whole, and they slide down the pelican’s throat easily. In some cases, the fish is too big to be swallowed, but the spines will get stuck in the pelican’s throat which means that the fish will be stuck and the pelican will simply starve.
How successful are pelicans at catching fish?
Their diving success rate is highly variable and depends on experience. Adult California brown pelicans bring up fish from around two-thirds of their dives, while novices appear to have a lot of trouble; fewer than half survive their first year out of the nest.
How do white pelicans catch fish?
The American White Pelican floats on the surface of the water, ready to scoop up fish. As the bird lifts its head, water drains out of its pouch, and the fish go down with a gulp. The birds often work together to herd fish — they form a group, swim in a line, and dip their heads all at once, scooping up their catch.

Why do pelicans dive into the ocean?
Brown Pelicans fly just above the surface of the water. They circle high, then diving headfirst, plunge under water to catch fish. Several adaptations protect pelicans as they dive. First, they have air sacs beneath the skin on their breasts, which act as cushions.
Do pelicans herd fish?
In cooperative feeding behavior, groups of pelicans (usually less than 20) work together while swimming to herd small schooling fish into a dense ball or toward shallow water, where it’s difficult to escape. These white pelicans are gathering up into huge flocks as they finish their migration north.
How does a pelican catch its food?
The American White Pelican uses its beak to scoop up fish. Sometimes, these birds will fish in semi-circular or circular groups so they can concentrate fish for easy feeding. A pelican expands the pouch on its beak when it’s fishing, and sometimes when it’s stretching.
Do pelicans have big or small beaks?
Some beaks are big, with the ability to get bigger. For example, the pelican has a pouch-like beak it can expand when it’s trying to scoop up fish. Brown Pelicans are known for diving into the water to catch fish. However, American White Pelicans float on the surface and scoop up fish as they swim by.
How do brown pelicans dive after fish?
How Brown Pelicans Dive After Fish Without Breaking Their Necks The hefty coastal birds engulf fish as they plunge into the water from 60 feet up—all while avoiding injury.
Why do Pelicans shoot from their bill?
We know that pelicans “learn” this behavior because adults are better marksmen than young birds. Upon impact, the Brown Pelican opens its bill and expands its pouch, trapping small fish inside.
