Eagles have very complex migratory patterns, and not all eagles migrate. Eagles can
average speeds of 30 miles per hour, and while migrating ride columns of elevating air called thermals. Bald Eagles
will fly south when lakes and streams freeze over to find open fresh water.
New born Eagles will migrate before their parents and know instinctively where to travel, although some will
wander in a wide range in their formative years.
Adult Bald Eagles will usually migrate to the coast or large rivers near dams, where there's is
open water. Wind currents determine their flight pattern. Some eagles are migratory and some prefer to stay in the
same location, for instance eagles that live in Florida will not migrate, and will remain there year round. After
migration Eagles that flew south will return to the north once again to nest.
Bald eagles tend
to migrate in groups of about twenty to thirty miles long, with birds spread out about a half mile apart.
While we do know that wind currents tend to play a pretty large role in determining their flight pattern it is
baffling and complex.
For example young eagles migrate before their parents and it’s hard to say how they know how to achieve this
migration while being so young. Could it be instinct? Most bald eagles follow the food so to speak and often head
out near the open water.
These bold travelers fly in sunlight and are able to go long distances because of thermals which allow
these bald eagles conserve energy and soar using less wing –flapping.
