The Florida Fish and Wildlife Conservation Commission (FWC) has approved removal of the peregrine falcon from the state's list of endangered species.
DDT nearly killed them all
The peregrine falcon has become one of the best examples of how conservation practices can help a species to come back from the brink of extinction. DDT usage in the United States nearly wiped out entire populations of birds decades ago, including the peregrine falcon. Fortunately, before the peregrine falcon became extinct, the use of DDT was eliminated.
At least 3100 pairs
As a result of pesticide regulations and captive breeding-and-release efforts, the peregrine falcon made a dramatic comeback from precipitously low numbers in the 1970s. Peregrine populations dropped from about 20,000 birds prior to the 1940s to 650 birds in 1965. Of the two populations of peregrine falcon that pass through Florida, there are now at least 3,100 breeding pairs. The U.S. Fish and Wildlife Service delisted the species nationally in 1999.
Contamination is an ongoing threat throughout much of the wintering range of the species because many South and Central American countries lack the pesticide regulations that have been enacted in the United States. Peregrines do not breed in Florida, but they are commonly seen in the state. Many peregrines migrate through in the autumn and some may stay during the winter.

I would like to offer the facts on the peregrine falcon, falconers and the history of the recovery of the peregrine.
The peregrine is no longer considered endangered or threatened anywhere in United States by the Fish & Wildlife Service under the Endangered Species Act (ESA). Studies have shown that passage raptors taken for falconry and released the following spring have a better chance for survival then if they had been left in the wild. Due to these and other factors, falconry has never been shown to have had a significant impact on raptor populations. The peregrine population over the years has increased statistically. The past several years have show that breeding numbers of peregrines in the Eastern US and Canada have climbed to over 5000 pairs of peregrines, a population larger than the pre-DDT estimates.
The peregrine falcon populations in the U.S. have continued to increase and show no sign of having reached an upper limit. A fair estimate of the North American peregrine population is 20,000 breeding pairs. Being healthy, this population produces 40,000 young per year. The peregrines that were being held for falconry in captivity were used 30 years ago as breeder birds where given up by falconers to repopulate the wild population.
Falconers also designed the current methods used to breed raptors in captivity to help repopulate peregrines. Working hand in hand with Federal authorities Falconers went to wild Peregrine nest sites and removed the un-cracked eggs to be incubated and then returned chicks once they were hatched to the nest sites.
The peregrine falcon has a long and extraordinary history, especially to the falconry community. The peregrine falcon is the iconic symbol of the art and sport of falconry. Their use in falconry has been written about for hundreds of years. As a sport, falconry has no equal and as falconers we are privileged to have a front row seat to nature in all her grandeur -- for that reason falconry has been called at times the sport of kings.
Delisting the peregrine falcon and allowing for a limited take for their use in falconry would be the culmination to one of the most successful recoveries of an endangered species ever. By delisting the peregrine falcon you would recognize the efforts of thousand of people over several decades and prove that, together, we are all capable of doing so much when a species is in peril.
I’ve heard those opposed to delisting agree that the peregrine has fully recovered from a biological point, yet they remain against a wild take stating falconers can obtain captive bred peregrines. Though this is true, it is not the same. All treatise on falconry, written hundreds of years ago up to the listing of the peregrine, state that the passage (wild taken) falcon is the perfect bird for falconry, free of all the bad habits of a captive raised or eyass taken from the nest. Being given the opportunity to take and train a passage bird is the dream and desires of many a falconer.
Everyone from the state to the Audubon society all agree there is no biological or ethical reason for the peregrine falcon to remain on the state threatened list.
In closing,
The falconry community has earned the right thru years of hard work and love of the raptors it employs to enjoy one of natures most iconic predators for it’s use in the sport of falconry.
If you see a peregrine today thank a falconer..
Respectfully,
A Florida Falconer
