A checklist of birds that you may find in Frick Park, P.A. developed by the Three Rivers Birding Club of Pittsburgh.
The Spotted Sandpiper (Actitis macularius syn. Actitis macularia) is a small shorebird, 18–20 cm long. Together with its sister species, the Common Sandpiper (A. hypoleucos) they make up the genus Actitis. They replace each other geographically; stray birds may settle down with breeders of the other species and hybridize.
