Sea Eagle

Several types of birds of prey are called "sea eagles". These include African fish eagles, Steller's sea eagles, and bald eagles.
About

Name: Sea Eagle, Erne, Ern (Haliaeetus) - any bird of prey in the genus Haliaeetus

Length: 60 cm to 105 cm, depending on species.

Weight: 1 to 9 kg, depending on species.

Location: Close to rivers, lakes, and tidewaters worldwide except in South America.

Conservation status: The eagles rank from Critically Endangered (Madagascan fish eagle) to Least Concern, depending on the species.

Diet: (Depending on location) Fish, small mammals and birds, carrion, crabs, molluscs, sea snakes, crabs, tortoises.

Appearance: All but the Sanford's and Pallas's are white-bellied and have white tails. Heads are either white or tan, depending on the species. All beaks feature a high arch.

How do Sea Eagles feed?

Sea Eagles are primarily fishers, diving and snatching prey from just under the water's surface. They will also steal food from competitor birds like the osprey. If they catch a fish too heavy to fly with, they will swim back to shore. Eagles have a pouch in their chests called a crop, which stores food until the stomach is ready for digestion.

How fast do Sea Eagles fly?

Flight speed varies by species. For example, the Bald Eagle travels at 30 to 50 km per hour, with bursts up to 120 km per hour.

What are Sea Eagles birthing rituals like?

Sea Eagles mate for life, only taking a new mate if one dies. Nests are built in tall trees or on cliffs if trees are unavailable. Nests range from 1.5 to 3 meters across to accommodate growing hatchlings. Females lay 1 to 3 eggs, which are incubated for a little over a month. Hatchlings, known as eaglets, stay in the nest for about 13 weeks, practicing flight before their first actual flight, called fledging. It takes about 5 years for eaglets to develop full adult feathers and coloring.

How long do Sea Eagles live?

Sea Eagles generally live between 20 and 30 years in the wild.

How many Sea Eagles are there today?

Worldwide estimates:

  • Bald eagle - 70,000
  • Stellar's sea eagle - 6,400
  • White-tailed eagle - 22,000
  • White-bellied sea eagle - 10,000 to 100,000
  • Madagascan fish eagle - 80
  • Pallas' fish eagle - 2,500 to 10,000
  • Sanford's sea eagle - 375 to 1,500
  • African fish eagle - 300,000

Do Sea Eagles have any natural predators?

Sea Eagle eggs and eaglets are prey to other birds and tree-climbing mammals like raccoons.

Greenland: Where the Kayak Was Invented

If you've ever enjoyed kayaking, you owe a debt of gratitude to the ancient Greenlandic Inuit who originally designed them for hunting. The thrilling adventures people now have navigating some of the world's most challenging rapids wouldn't be possible without the Inuit's need for a nimble form of water transportation. While travelers still use kayaks in this region, they are typically not fishing, whaling, or sealing. Consequently, recreational kayaks have been adapted to fit their new role.

The Norse Settlement of Greenland

Erik the Red is a significant and vibrant figure in the history of the Norse Vikings. His story is primarily documented in the Icelandic Sagas Huaksbók (14th Century) and Skalhóltsbók (15th Century). These accounts offer slightly different versions of events that occurred 3-400 years earlier. The original saga of Erik the Red is believed to have been written around 1200 A.D., with the Skalhóltsbók version considered closest to the original. Additionally, Flateyjarbók (13th Century), which includes the Saga of the Greenlanders, is a crucial source for understanding the settlement of Greenland and the discovery of Vinland – North America.

Anyone who ventures to the right part of the globe can encounter vast amounts of ice, but a Greenland cruise offers something truly unique: ice sculptures hidden beneath the northern ice sheet. Scientists once thought these sculptures were rocky hills buried in ice, similar to the Ghost Mountains in Antarctica. However, it turns out that Mother Nature has crafted one of the most exclusive art exhibits in the world. These sculptures are not visible from the surface, but some scientists have managed to get a sneak peek using radar equipment.

The bowhead whale typically resides near pack ice, often in shallow waters. These whales are commonly found north of Europe, between Canada and Greenland, in the Hudson Bay area, the Okhotsk Sea, and the Bering, Chukchi, and Beaufort seas. In these regions, they filter food through their large baleen plates. Bowheads are known to open their large mouths and graze along the surface, in the water column, or on the sea floor.

Grasses, sedges, and other species of heath were the first arrivals, and are still commonly found in Greenland. Scientists have been able to work out how plants colonised Greenland by examining ancient pollen samples found in deposits at the bottom of lakes: Dwarf birch came to western Greenland around 9,000 years ago, and around 4,500 years ago – roughly the same time humans were first boating onto Greenland shores – green alders were taking up residence there.
