The airspace over Greenfield was busy with bird traffic on Sunday. One of those birds was in control.
Around noon Anne Marie Bosnyak, Linda Schmidt and I were chatting at a table outside the Staghorn Cafe when Anne Marie pointed out four distant turkey vultures. She’d left her binoculars in the car so she wasn’t sure about the fourth one. With my binoculars I identified it — a peregrine falcon. At that distance I couldn’t tell if it was immature or adult.
Most birds avoid flying near peregrines because of their swift pursuit of avian prey and fierce territoriality. The vultures were no exception. They circled together and moved westward, away from the peregrine heading south.
The peregrine rose in the heated air, then noticed a pair of dark birds rapidly heading west and turned to follow them.
Ravens. As if to acknowledge the peregrine’s presence one of them tumbled three times in the sky but they didn’t slow down. The ravens left without incident.
The peregrine circled lazily in the heat and then something really interesting flew below him — an adult bald eagle heading toward the Monongahela River.
As I watched, the peregrine dove several times at the bald eagle and drove it lower and away. Even through binoculars I could see the eagle flinch as it tried to evade the peregrine. They disappeared over the horizon toward Hays.
In Pennsylvania peregrine falcons control the airspace whenever they want to. Bald eagles don’t stand a chance, as shown in Peter Bell’s photo above.
