Migisi

Bald Eagle (Haliaeetus leucocephalus)

Migisi came from Claire County, MI after having fallen from her nest at about six weeks of age. She was treated at MSU for a fractured leg but unfortunately  developed bumblefoot and became imprinted on humans. She was transferred to Nature’s Nursery for rehabilitation but due to the damage her leg sustained and imprinting, she was unable to be released to the wild. In November 2006, Migisi was transferred to the Medina Raptor Center where she eventually found her permanent home in September 2007.  She has became one of our most admired and requested educational ambassadors who brings joy to servicemen, veterans, children and adults when she is presented at our programs.


About Bald Eagles

(Information taken from the Cornell Lab of Ornithology)

The national emblem of the United States, the Bald Eagle was threatened with extinction in the lower 48 states because of DDT (a type of pesticide) poisoning. Protection under the Endangered Species Act, together with reintroduction programs, brought populations up, and the species was reclassified as Threatened in 1995. By 1999, some were suggesting removing the eagle from the Endangered Species List.

Sex Differences

Sexes alike in plumage, female larger

Immature

Immature variably patterned with dark brown and white; takes five years to acquire full adult plumage. White not restricted to well defined areas, but appearing scattered throughout body, usually with brown mottling in same area. White in wings primarily in linings and not flight feathers. Bill and cere blackish gray. Eyes dark brown. Feet and lower legs yellow.

Food

Summer Range:

Breeds near water from Alaska throughout Canada and in scattered localities in nearly all of the United States. Also a small number in Mexico.

Winter Range:

Winters in coastal Alaska and Canada, and throughout lower 48 states

Habitat
  • Breeds in forested areas near large bodies of water.
  • Winters in coastal areas, along large rivers, and large unfrozen lakes.
Behavior
Foraging:

Gets food by direct capture, scavenging, and stealing prey from other eagles or other birds and mammals. Will wade in water to catch fish.

Reproduction
Nest Type:

Large nest of sticks. Lined with finer woody materials. Reused over many years. Placed in large tree, often the largest in the area. Rarely nests on ground or cliff.

Egg Description:

Dull white, usually without markings

Clutch Size:

Usually 2 eggs. Range: 1-3

Condition at Hatching:

Capable of limited motion. Covered with light gray down and with eyes open.

Conservation Status

Preservation efforts brought populations in the lower 48 states back from near exinction in the mid-20th century. Although the Bald Eagle was proposed for removal from the Endangered species List in 1999, populations in the lower 48 states remain relatively low. Humans are the most important source of mortality.

Sound

Call high-pitched whistling or piping
