Ricketts Glen State Park provides a breeding habitat for four species of flycatchers and two species of waterthrushes. American bittern nest near the park. Bald eagle are frequent visitors to the park, and some ornithologists believe they may be nesting there since adult pairs have been observed with their young. The park is a nesting location for three "rare" birds, including two birds of prey (the northern goshawk and northern harrier), and Swainson's thrush, as well as one "at risk" duck, the green-winged teal.
