North American Bald Eagle


Female Bald Eagles are slightly larger than the males.  Immature eagles are a mottled brown and white, with the distinct white head and tail of the mature bird developing between 4-6 years of age. 


Eagles travel by soaring and gliding on thermals, which are columns of rising air, which allows them to cover great distances without flapping their wings. Eagles follow seasonal food supplies; as lakes and streams freeze over, they must go south to find open fresh water or head to the coast.  Bald eagles are aggressive hunters but will often scavenge dead prey or even steal it from another bird when the opportunity arises.

Our Animals

We have one male and one female Bald Eagle here at PPZ. Both were rescued from the wild and are in captivity because they cannot fly due to wing injuries.  We believe the male may have sustained injuries during a dust up with a great horned owl.  All Bald Eagles in zoos are actually on loan from the US Government.
