PPL’s Peregrine Perch

We’re excited to provide viewing and learning opportunities

PPL Electric Utilities, joined by WFMZ-TV, is proud to offer this live video feed of the peregrine nesting box near the top of the PPL Corporation headquarters building in downtown Allentown. Note: Some video will contain images of falcons consuming their prey.

Peregrines mate with the same partner and typically lay three to five eggs annually.

PPL’s commitment to helping peregrines spans decades

PPL has a long-standing involvement with efforts to restore the peregrine falcon population. In 1995, the company began its support of the Lehigh Valley Peregrine Project to release young peregrine falcons from the top its 322-foot headquarters building in downtown Allentown in the hope that the falcons would come back to the area. We also built a nesting box on our headquarters building.

In 2018, a pair of peregrines returned to the PPL building to nest, marking the first time since 2008 that peregrines successfully nested there.

Falcon Facts

  • The use of the pesticide DDT decimated peregrine populations in the middle of the 20th century, but the population has rebounded thanks to conservation efforts.
  • Peregrine falcons are mid-sized birds of prey, about 15 to 22 inches long, with a wingspan of more than three feet. They weigh just over two pounds.
  • Baby peregrines are called eyasses and weigh about 1.5 ounces when they hatch. They eat a lot of food, doubling their weight in only six days. At three weeks, they are ten times their hatch size.
  • Eyasses usually start to fly in about 42 days. After fledging, they are still dependent on their parents for food until they learn to hunt, which takes about a month and a half.
  • They can live up to 15 years.
  • Peregrines primarily eat other birds, including pigeons, flickers, jays and thrushes. They also eat bats.
  • An adult peregrine can reach a speed of more than 200 miles per hour in a vertical dive and averages about 60 miles per hour in level flight.
  • In the wild, falcons nest on high cliffs.
  • In urban settings, tall buildings – such as PPL’s headquarters – make a suitable alternative.

Other ways PPL helps

Osprey and Bald Eagle Nests

PPL has been installing nesting platforms for osprey and bald eagles for more than 20 years. These platforms provide alternative spots so they don’t build their nests on high-voltage transmission line structures.

Feeding Giraffes

PPL helps to feed the giraffes at the Lehigh Valley Zoo by providing some smaller branches from our vegetation management program.

Homes for Songbirds

When clearing transmission right of ways, we carefully leave brush behind that helps create new habitats for birds and other wildlife.
