I have a love for raptors, and raptor watching. Its great to go into a park and find these huge birds of prey in their environment. Here is PA one doesn't need to go far to see Bald Eagles and Owls. I have seen very rare birds in the past. It ties in well with backpacking and hiking... A quick drive gets me to Hawk Mountain Sanctuary in the fall.
There was an Old Man with a owl,
Who continued to bother and howl;
He sat on a rail, And imbibed bitter ale,
Which refreshed that Old Man and his owl
