A bald eagle pair has become the first of their species to become parents in the Cuyahoga Valley National Park in 70 years.

Rangers are encouraging humans to keep their distance from the birds, which have set up housekeeping high in a large tree.

Pedestrians have been banned from the railroad tracks near the nest, and signs posted on a hiking trail urge walkers not to linger near the nest, The Cleveland Plain Dealer reported.

A pair of bald eagles nested in the same area in the park last year but produced no eggs.
