 They are not bald - their head feathers are white, bodies are dark brown. Juven-
iles are a mottled brown/white for about four years.
 They live up to 40 years.
 Eagles stand up to one meter tall and have wingspans that measure 2-2.5 m/ 6-8
ft. Females are about 25% bigger than males.
 Eagles can fly up to 3000 m/ 9750 ft high and reach speeds of up to 80 kph/ 55
mph.
 It is believed that they mate for life. When courting, they perform a special
courtship dance in the sky that involves locking talons and cart-wheeling through
the air.
 They lay 1-3 eggs and the 35-day incubation duties are shared by both mom and
dad.
 Eagles nest in the same place, building the largest nests in North America. The
pair adds to it every year with some nests achieving weights up to a metric ton.
 Habitat ranges across most of Canada, the United States and northern Mexico.
They like old-growth forests for their large nests and large bodies of water with
abundant food supplies.
 If an eagle pair's territory has access to open water they are likely to stay there
year-round. However, if the water body freezes over, making it impossible to fish
the eagles migrate elsewhere.
 Eagles are fish eaters but also opportunistic. They will scavenge carcasses or
hunt for small mammals like mice, rabbits, raccoons, even small deer fawns.
