Wildlife near Philadelphia, Pennsylvania

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.

Most-observed species near Philadelphia

Built from recent research-grade iNaturalist observations. Identifications are community-sourced and may occasionally be wrong, and the ranking reflects where people record and photograph wildlife, so a species seen often here is not necessarily rare elsewhere. Some plants and animals are only out in certain seasons. Treat this as a lively snapshot of what people are finding, not a formal checklist.
