In 1974, the Peregrine Fund was started. It began a mission to rescue and restore the peregrine falcon, working with numerous organizations in both the United States and Canada.
Peregrine falcons were successfully produced in captivity by Cornell University researchers. In a lab, Peregrine falcon eggs were hatched. Up until the age of three weeks, the chicks were nurtured in the lab.
When their survival abilities were sufficiently developed for them to become independent, they were then put in artificial nesting sites where they were fed and cared for by unseen humans.
This method has allowed for the release of over 6,000 American Peregrine falcons in North America since 1974.
Populations of Peregrines are currently healthy in the United States and Canada, and in some parts of the world, they may even be more numerous than they were before the species’ fall in the 20th century.
