Have you noticed the transition at the Pitt peregrine nest in the last two days? This boring picture demonstrates it.
Brooding is over. The chicks can regulate their own body temperature so their parents don’t need to shelter them all the time. Here they are asleep, surrounded by the feathers and body parts (wings) of this morning’s breakfast.
Where’s Mom? She’s guarding them out of camera view or is out hunting while Dad stands watch. She knows her nestlings will be fine alone.
For more information on peregrine falcon behavior see the Peregrine FAQs page on this blog.
