Good news about the Peregrine's continued recovery
The results from the first nationwide monitoring effort to measure the peregrine falcon’s recovery put the number of nesting pairs in North America at about 3,000 – nearly 10 times the number estimated in 1970 when the bird was first protected as an endangered species and considerably more than the roughly 1,800 breeding pairs estimated in 1999, when the peregrine was declared recovered and was de-listed.You can see the post-delisting monitoring plan here and the 2003 monitoring results here.
