John Heinz National Wildlife Refuge, Tinicum, Pennsylvania
This juvenile hawk has been spending the winter hunting in and around the meadows that surround the refuge's parking lot. I've seen it four separate days over several weeks, and often at the beginning and end of my walks.
"A hawk of the woodlands, often heard before it is seen. The clear whistled calls of this hawk are conspicuous, especially in spring; in the east, Blue Jays often give a near-perfect imitation of this call. Over much of eastern North America the Red-shoulder has become uncommon, sticking closely to the remaining forests. Populations in Florida and California are often more visible, perhaps adapting better to open habitats."
