The golden eagle is not on the federal threatened or endangered list, but has disappeared from most of the northeastern states. Osprey The osprey, Pandion haliaetus , is a large, eagle-like hawk found throughout North America and in the Eastern Hemisphere. It inhabits seacoasts and the areas near large rivers and lakes. In Pennsylvania, it shows up along the Susquehanna and Delaware rivers, and near creeks, ponds, lakes and reservoirs throughout the state, depending on the season.
Plumage is dark above, white below.
Adults and juveniles are colored alike. The head is largely white, with a black patch across each cheek. Except when migrating, ospreys flap more than they sail. Wingbeats are slow and deep. Ospreys hover 50-150 feet up and then plunge to the water for their fish prey, sometimes going all the way under.
