Recently while at Piscataway Park, we witnessed two adult eagles, one each on/around a nest, on different ends of an island off the point (I know it has a name, I just can't think of it right now). The island can be seen from Fort Washington National Park, too. One of the eagles was being harrassed by crows (one brazen enough to sit directly under the nest) and flew to sit on branch not too far away from the other.
