Vulnerable Birds in Allegheny County

Highly and moderately vulnerable birds may lose more than half of their current range—the geographic area where they live—as they are forced to search for suitable habitat and climate conditions elsewhere.

Below, find out which of the birds that nest or spend the winter in your area are most vulnerable across their entire range. Some birds may lose range outside of your state, making the protection of their current habitat in your area even more important.

How Will the Eastern Towhee's Range Be Affected in Allegheny County?

Rising temperatures and shifting weather patterns affect birds’ ability to find food and reproduce, which over time impacts local populations, and ultimately continent-wide populations, too. Some species may even go extinct in your state if they cannot find the resources they need to survive and raise their young.

Select a warming scenario to see how this species’ range will change under increased global temperatures.

Reducing warming makes many types of birds found in Allegheny County less vulnerable.

Without immediate, urgent action to reduce carbon emissions, global temperatures could rise by 3.0°C in the coming decades, endangering birds in your area. The threat is drastically reduced if we curb greenhouse gases and we limit warming to 1.5°C, giving the same birds a chance to not only survive but thrive.

Click the three different warming scenarios to explore how increased warming puts more species in Allegheny county at risk.

Pennsylvania's Birds and Habitats

In central Pennsylvania, the hardwood forests of Bald Eagle State Park host Ruffed Grouse, Ovenbirds, and Hooded Warblers. On the shores of Lake Erie in Presque Isle State Park, waterfowl find shelter from winter storms and migrants rest in spring and fall. Kittatinny Ridge is a raptor-migration corridor, and nearby deciduous forests support Wood Thrushes and Canada Warblers. Within the Delaware River Watershed, forests, parks, and open space provide critical habitat for birds, while Delaware Bay’s marshes and beaches serve as vital stopover points for migratory shorebirds.

(Data: U.S. EIA)

Pennsylvania’s clean energy economy is expanding, with over 90,000 employees as of 2019. The state released a climate action plan in 2018, though it may require stronger implementation plans.

Pennsylvania is a participant in the Regional Greenhouse Gas Initiative, a cap-and-trade program in the northeastern and mid-Atlantic United States that aims to reduce carbon emissions from power plants.

Climate Threats Facing Birds and People in Allegheny County

Flooding along the Ohio and Allegheny Rivers in Pennsylvania disrupts commercial navigation and threatens riverfront communities. Sea levels have risen by one foot along some parts of the Delaware River and will likely rise up to three feet in the next century, harming coastal communities, eroding beaches and wetlands, and threatening drinking water supplies for millions. In the coming decades, Pennsylvania will likely experience increased flooding and disrupted ecosystems.
