In the Great Lakes region fishermen complain about double-crested cormorants competing with them for fish and demand that they be killed but in other countries fishermen work with cormorants to catch the biggest fish.

Cormorants naturally hunt and catch fish underwater. Those who fish with cormorants train them to bring large fish back to the boat by placing a loose snare around their necks that allows them to swallow small fish but not large ones. When they bring a large fish back they are fed small fish as a reward.

The origins of cormorant fishing are obscure but the practice is still used today in China, Japan, Peru and Greece, though mainly for the tourist industry. Only in southwestern China is it still employed commercially.

The species of cormorant used depends on what is native to the area. In China, the great cormorant (Phalacrocorax carbo). In Japan, the Japanese cormorant (Phalacrocorax capillatus). In Peru, the neotropic cormorant (Nannopterum brasilianum).

Watch cormorants at work in southwestern China.

Midway Atoll hosts the largest Laysan albatross (Phoebastria immutabilis) nesting colony in the world where more than 600,000 pairs raise young each year. The birds are absent in September but return to court in November, lay eggs in December, and hatch in February.

There are so many birds that it’s hard to count.

After the eggs hatch the chicks begin to wander in March while their parents hunt at sea. By May the chicks start to grow adult feathers but it will take two more months before they are ready to fledge in July. During this period they are everywhere …

In open spaces …

… near buildings …

… under trees and on the roads.

On the Fourth of July a rain shower prompted the chicks to flap their wings, shown in two videos below. You can hear the raindrops on the audio tracks.

Nearly ready for takeoff!

As soon as they fly, Laysan albatross youngsters leave Midway for a life at sea. USFWS Pacific says they are “likely to move towards Japan or Alaska, but their known range extends to Mexico, too.”  They won’t return to Midway Atoll until they are three years old. They don’t breed until age seven or eight.
