Hawk Mountain Sanctuary is a wild bird sanctuary in Albany Township and East Brunswick Township, located along the Appalachian flyway in eastern Pennsylvania. The sanctuary is a prime location for the viewing of kettling and migrating raptors, known as hawkwatching, with an average of 20,000 hawks, eagles and falcons passing the lookouts during the late summer and fall every year.

Hawkwatching is a mainly citizen science activity where experienced volunteers count migratory raptors in an effort to survey migratory numbers. Groups of hawkwatchers often congregate along well-known migratory routes such as mountain ridges, coastlines and land bridges, where raptors ride on updrafts created by the topography. Hawkwatches are often formally or informally organized by non-profit organizations such as an Audubon chapter, state park, wildlife refuge or other important birding area. Some hawkwatches remain independent of any organizing structure.
