Closures were initiated in Zion National Park March 1 in order to protect peregrine falcon nesting areas. All climbing routes on cliffs used by nesting peregrine falcons in Zion National Park have been reopened.
During the nesting period, park wildlife biologists monitored the birds’ activity, and found five different territories were occupied by pairs of adults. Six juveniles successfully fledged: two on the Tunnel Wall, two on Mount Kinesava, one on Cable Mountain, and one on Mount Isaac.
The cliffs of Zion National Park are home to a high concentration of breeding peregrine falcons each spring and summer.
“Peregrines are amazing fliers who catch birds and occasionally bats in mid air,” said Cassity Bromley, chief of resource management. “These magnificent birds of prey were listed as an endangered species in 1970 under the Endangered Species Act. Following the United States ban on DDT and captive breeding efforts, peregrine numbers rebounded, and they were removed from the endangered species list in 1999.” Zion National Park has been, and continues to be, a sanctuary for peregrines and many other wildlife species.
