Klingsberg Aviary

Shaver’s Creek Environmental Center is a beautiful place for anyone interested in the natural world.

Cyrus Klingsberg, benefactor of the Cyrus and Vera Klingsberg Aviary

Shaver’s Creek Environmental Center is home to a variety of birds, including hawks, owls, eagles, vultures, and falcons — a group known as raptors.

All of our resident birds arrived from rehabilitation centers with permanent disabilities, and they are permitted to Shaver’s Creek to work alongside our Animal Care staff and volunteer team as ambassadors for their wild counterparts. Stop by to meet our feathered coworkers — watch a training session, observe a vulture displaying natural foraging behavior, or see a Golden Eagle tearing up enrichment.

The public is invited to visit Shaver’s Creek on the weekends from mid-June to November for Meet the Creek, a free public program where an interpreter answers questions and shares information about our resident birds with our visitors.


The Klingsberg Aviary is wheelchair- and stroller-friendly, but if you require special parking accommodations, please call Shaver’s Creek at 814-863-2000 for more information when planning your visit.

Our Resident Animals

American Crow

Crow on perch

Highly adaptable and widespread, crows are some of the most well-known and commonly spotted birds in North America. They socialize in a variety of groups and are highly resourceful. Despite being common, there is still much to be discovered about this brilliant species!

American Kestrel

American Kestrels require natural tree cavities, nest boxes, or buildings for breeding. Kestrels are beneficial predators in farmlands, preying on a variety of agricultural pests. Unlike most raptors, American Kestrels differ in appearance between male and female.

Bald Eagle

bald eagle

The Bald Eagle was on the brink on extinction in the lower 48 states in the latter half of the twentieth century due to illegal hunting and DDT. However, through diligent effort from government agencies, conservation groups, environmental regulations, as well as the Bald and Golden Eagle Protection Act, our national emblem has made an incredible recovery and was removed from the endangered species list in 2007. In winter, Bald Eagles may congregate in large numbers around bodies of water, preying on fish and waterfowl.

Barred Owls

Barred Owl

Listen for Barred Owls calling at dusk and dawn with a distinct 8-note “hooting” call (“Who cooks for you? Who cooks for you all?”). Barred owls do best in old growth forest, where they nest in secondary tree cavities.

Black Vulture

Black Vultures are known for their ability to scavenge on carrion, making them essential to maintaining cleanliness and reducing risk of diseases such as rabies and botulism. Matilda, our Black Vulture, demonstrates this by picking through enrichment objects to find morsels.

Broad-winged Hawk

Watch for migrating Broad-Winged Hawks during the months of September and April, forming groups called “kettles” in thermals or slope-soaring along Pennsylvania ridges. This small, stocky species depends on large tracts of forest to breed.

Eastern Screech-Owl

Eastern Screech-Owls habituate well to human habitats, oftentimes residing in suburban neighborhoods and city parks. Eastern Screech Owls nest in tree cavities.

Golden Eagle

Golden Eagles migrate through central Pennsylvania, but generally when cold, northwesterly winds strike our ridges in late fall and winter. A few winter in rural areas of the state. One of the best place to observe Golden Eagles in the east is just a few miles from Shaver’s Creek on Tussey Mountain.

Great Horned Owl

Sunny, the Great Horned Owlet

With their tufted, earlike plumicorns, deep hooting call, and striking yellow-eyed gaze, Great Horned Owls have an allure that is favored in storybooks and on screen. This iconic reverence empowers them as a flagship species in conservation efforts for all owls and birds of prey. These charismatic predators are adaptable in both their prey and their habitat. They eat anything from dainty mice and frogs to mammals and birds even larger than themselves and can be found everywhere from the Arctic to the tropics, from farms to cities, and from forests to backyards.

Peregrine Falcon

Keep an eye to the sky. Peregrine Falcons are the fastest animals on the planet as they dive at speeds around 200 mph to hunt their avian prey. And along with Bald Eagles, Peregrines are making a steady comeback after the banning of DDT, a harmful pesticide that caused this species to lay too-thin and easily-breakable eggs. Pennsylvania-born scientist Rachel Carson was instrumental in calling attention to the ecological impacts of DDT with her 1962 book, Silent Spring.

Red-tailed Hawks

One of the most widespread and successful raptors in North America, they have adapted well to human habitats, including highway medians and cities. Soaring hawks like Red-tails are known as Buzzards on other continents. Like all migratory birds in the United States, they are federally protected by the Migratory Bird Treaty Act of 1918. This makes it unlawful to possess, pursue, hunt, take, capture, or sell birds or their parts (including feathers, eggs, and nests).
