These swift changes affected a species of bird that seemed impervious to defeat. Traveling over 15,000 migration miles in a single year, it is considered to be the fastest animal on earth, stooping toward its prey at between 100 to 200 mph. It hunts and mates on the wing, rarely needing to come down to earth to perform the simplest tasks. Nests are scraped into nooks of sandstone cliffs hundreds of feet high. Only by rock climbing, canyoneering, or high powered scope could one get a glimpse of the private rituals of the "wandering" avian family.
The word peregrine means wanderer. 1970 was the year this graceful falcon was almost gone - only 39 breeding pairs remained in the lower 48 states. All were extirpated in the eastern US and between 80 to 90 percent were dead in the west. In 1962, after the release of an electrifying book which proved beyond a doubt that decades of use of pesticides led to the peregrine falcon's sharp decline, the world was awakened to a chemical disaster. Silent Spring by Rachel Carson clearly explained the scientific reasons behind the causes of dwindling numbers of animals and their effects on the food chain. This publication launched the modern environmental movement. DDT (the chemical primarily responsible for the falcon's downfall) was banned in the US, and with the help of Dr. Tom Cade of Cornell University, 1970 ushered in one of the most successful recovery efforts ever undertaken. The goal: bring back the peregrine falcon from the brink of extinction. Now over 4,000 breeding pairs of falcons fly once more, their bodies no longer full of pesticides. Wild-born chicks hatch from shells strong with calcium, not fragile from its absence due to the compromising nature of DDT. Dr. Tom's organization, The Peregrine Fund, also helps the California condor, the bald eagle, and many others.
What's great about visiting Zion National Park is that the park has always been an important part of this vital recovery effort. The Peregrine falcon, the California condor, and the bald eagle are all found here. This place of protection and sanctuary harbored these birds with a safe haven where their needs for food, nesting, and habitat never changed. Peregrine falcon returnees established 13 nesting sites over the years and all of their food sources in the park are free of man-made dangers. The US Fish and Wildlife Service's fledging goal for 2008 was 1.25 chicks per breeding pair of falcons. By August of 2008, 2.16 chicks per pair winged their way to their winter home somewhere, we believe, in Central and South America. The California condors can be seen in the Lava Point, Canyon Overlook, and Angels Landing areas of Zion. Bald eagles come home to Zion for their winter rest. Celebrating these success stories is something that happens often in the park.
You can celebrate too. When visiting Zion, each time you look up and see any of the 288 species found on the park's bird list, take heart in knowing that by being here you help them thrive. You offer your highest and best to the idea that all of nature contained in our 232 square mile sanctuary, and beyond, is worthy of saving. May the wandering spirit of all our avian friends inspire in you a new understanding of what it means to fly free.
