Here in (around) Cleveland Ohio, only two may be three pair of Eagle nesting, so very rearly can be see them.
A pair of eagle took over a Heron nest just right above a paved all purpose trail in a Cuyahoga Valley N.P.
To prevent the people to watching the eagles, there was a ranger around all time to give a fine to everyone who stop to take a look on a nest! They let the people walk on a trail under the nest, but to stop and look at the nest wasn't allowed. This is a free country! You can do whatever you wa... no whatever a goverment let you do! Basicly NOTHING!

You can't even watching the eagles not to photographing them!
In Alaska also illegal to stop to watching Eagles?

I shoot on Fuji Velvia and Astia, with Nikon F6 and Pentax Z1p with Sigma zoom lenses.
