For those who haven't set out on an eagle-watching expedition, here are some tips.

Dress warm. Eagle-watching can involve plenty of standing around.

Watch for traffic, especially along Hwy. 61. Drive into pullouts, and then look for eagles.

Can't see any eagles flying? Look for birds on the ice or perched in trees. The white heads stand out more clearly than the dark bodies.

Seeing brown: The big all-brown birds you see are immature bald eagles. Bald eagles -- both male and female -- develop their white heads at age 4 or 5.

Bring binoculars or a spotting scope.

Keep your distance: Garrigan suggests "give them a little space." If you spot an eagle roosting nearby, try watching it from the car to disturb it as little as possible.
