Nockamixon state park has bald eagles, osprey and all kinds of wildlife. It's big enough, even when it's crowded, you can find quiet, secluded spots.

Lake Galena in the Doylestown area has a nature preserve on the east end of the lake. Birds, turtles and deer hang out in the area of the Nature Center.

Edit. I misread where OP is from. These places are a good way away. But would make a cool weekend trip.
