FACTS ABOUT WISDOM

Wisdom is a Laysan Albatross, Phoebastria immutabilis
The Laysan Albatross is best known for its gliding flight, awkward landings, and elaborate courtship rituals. These birds spend nearly half the year at sea, not touching land until breeding season. Though large for a seabird, the Laysan is small for an albatross. They may live more than 40 years. These birds are named for Laysan, one of their Hawaiian island breeding colonies. There are over 450,000+ nesting pairs on Midway Atoll.

Born: Unknown, presumed Midway Atoll, c. 1950.
Weight: about 8 lbs.
Wingspan: about 6 ½ feet (77-80 inches)

The Midway Atoll is visited by almost two million birds every year. US President G.W. Bush designated the Northwestern Hawaiian Islands Marine National Monument.

TYPICAL YEAR FOR AN ALBATROSS (Destination Pacific)

January – late January, Laysan albatross chicks start to hatch
February – by end of month, all chicks have hatched
March – chicks starting to wander from nest
April – chicks continue to grow and become more adventurous
May – chicks show some adult feathers
June – chicks almost full grown; some adults leaving island
July – more juvenile Laysan albatrosses are fledging, and only a few adults remain on the atoll.
August – by early August, all juvenile Laysan albatross have flown
September – no Laysan albatrosses on island
October – late October, first Laysan albatrosses return
November – most return; by late November, some eggs are laid
December – most eggs are laid this month

For most of its life the albatross flies. In Wisdom’s 60+ years, it is estimated she has flown about 50,000 miles each year, for a total of about 2 to 3 million miles in her lifetime.

  2. Beautiful book about a wonderful bird. I love that the pictures in the book make me feel that I am back on the Midway. The message about plastics in our oceans is something for kids to think about at a young age.
