Birds that call Pennsylvania home are in serious decline.
Why it matters: Birds are indicators of the health of their habitats and signal early warnings of broader trouble to the environment, and potentially to people.
State of play: Over the past half-century, Pennsylvania species like the piping plover have lost half of their population, per the North American Bird Conservation Initiative's 2025 State of the Birds report.
- The report identifies the plover and king rail as a "Tipping Point" species, meaning they are highly vulnerable to extinction.
- That list includes the Wood Thrush and golden-winged warbler, which have experienced long-term population losses but have had relatively stable trends recently.
Zoom in: The Pennsylvania Game Commission lists several bird species as endangered and protected, including the great egret, black tern, and plover.
Zoom out: Species of Eastern forest birds, like the field sparrow in Pennsylvania, are declining due to habitat loss from residential development and agriculture.
Threat level: A blow to birds is a blow to the economy. From birding tourism to pest control and pollination, birds generate $279 billion annually for the U.S. economy, the report finds.
The big picture: It's not just Pennsylvania. Researchers tracked species nationwide and found declines almost everywhere — even among birds once thought resilient, like waterfowl.
- Roughly one-third of U.S. bird species — 229 in total — are now classified as high or moderate conservation concerns.
Yes, but: It's not all bad. Thanks to wetland protections, dabbling and diving duck populations have jumped 24% since 1970, while waterbirds are up 16%, per the report.
- And Pennsylvania has recently removed some species from its endangered list, including peregrine falcons.
What's next: Scientists are calling for bigger investments in habitat protection — particularly on private lands and in partnership with local communities and Indigenous nations.
