Philadelphia sits between the Schuylkill and the Delaware, and both rivers run wild at the edges. Bald eagles nest along the Delaware again after decades away, great blue herons and night-herons work the tidal marshes at John Heinz refuge, and the Wissahickon gorge cuts a genuinely forested valley through the city with barred owls and white-tailed deer. In the rowhouse neighborhoods it is northern cardinals, gray squirrels, and red-tailed hawks on the church steeples.
