Osprey

Osprey -- Pandion haliaetus

The Osprey is commonly seen around Damariscotta Lake and any large body of water where fish live in large numbers.

Food

Fish less than one pound, unless feeding young. Caught by hovering about 70 feet above the water, stooping with wings folded in toward body and reaching speeds of 30 - 50 miles per hour, making small adjustments during dive. Before impact the feet drop and project ahead of the bird. The bird submerges sometimes as deep as three feet. With strong downward wing beats, the osprey surfaces and flies away with its prey, turning the fish head-first in its talons for better aerodynamics while shaking water off its feathers.

Special Adaptations

• Long, strong wings for efficient flight.
• Feet have long talons on strong toes. The outer toes can curve back for a better grip, which is also enhanced by spines on the footpads.
• Oily, dense feathers to help keep the bird dry and more buoyant for surfacing.

Nesting

• Large stick nest located in treetops, on platforms, utility poles, navigation aids, etc. close to a water body with plenty of fish.
• Eggs 1 - 3, incubation 37 days, parents feed young through August.

Life-span

• About 50% survival of hatchlings in their first year.
• The birds must be two years old or more in order to breed.
• Successful adults may live 25 years or more.

Migration

• To Central and South America

Threats to their survival

• DDT, which is still used in their migratory grounds.
• Predation
• Occasional collision with trucks and automobiles on roads near feeding areas
