Join Wild Mount Diablo as we hear the story of how a local apex predator, the peregrine falcon, fared in 2022, following the difficult 2021 season, when all four chicks, banded and almost ready to fly, were killed by a great-horned owl in a territorial dispute. Follow MDIA’s Peregrine Team of naturalists, stewards, and detectives as they tell the story of how the fastest animal on the planet fared this last season.
