Peregrine falcons lay 4 eggs in Pitt's Cathedral of Learning nest
PITTSBURGH (KDKA) -- There are now four eggs in the peregrine falcon nest on Pitt's Cathedral of Learning.
The National Aviary said Carla and Ecco laid their second egg on Saturday around 9 p.m., the third egg came on the first day of spring and the fourth arrived on Thursday. The first egg was laid last week. The National Aviary says peregrine falcon clutches usually have four eggs.
"Peregrine eggs are tolerant to various temperatures and can sit uncovered in the nest box over the next several days," the aviary wrote. The aviary says peregrine falcon males don't incubate the eggs, but viewers may see Ecco temporarily help cover the eggs in inclement weather so Carla can rest.
The National Aviary has been documenting the adventures of Carla and her mate Ecco since February. Carla is new to the nest this year after Morela ended the last season without any eggs and disappeared around May. Carla laid claim to the nest box and Ecco shortly after that, the aviary says.
Carla will incubate the eggs for about a month before they hatch. This year, bird watchers can follow Carla and Ecco through the new camera and microphone, which was installed by Pitt's IT department.
Pittsburghers are also waiting for a few other eggs to hatch. There are two eggs in the eagle nest at the U.S. Steel Irvin plant.
