Lowell, nice job getting the stories, pictures and film clips pulled together. Its a great read and fun to see the early newspaper clippings and film. I am glad you are doing this on-line so we can see the rich history of all types of media. Thanks for your dedication.
Yes Ivan there is a huge old nest there. Golden Eagle nest sites like falcon aeries can be used for hundreds of years. I have read of gyrfalcon nests in Greenland that have prey remains documenting shifts in prey over the last few hundreds of years. This is one of the reason that agencies protect falcon nest sites. Once successful nest site is established by a pair they and may be used the site for the rest of their reproductive life.
Since you asked and I don't have time to read the above links, but as a biologist who is responsible for conserving migratory birds.
1. Yes, they are Federally protected under the Migratory Bird Treaty Act. Under that Act all take is prohibited unless authorized by the US Fish and Wildlife Service. Take under MBTA does not include disturbance like the Endangered Species Act. However, removal of active nests or young is defined as take.
2. Each Land Management Agency can establish it's own rules, regulations and policies to protect nesting peregrines, active nests and young. There are no standard guidelines on how far from a nest climbing can occur without disturbing the birds. No agency wants to see the peregrine re-listed and be the cause of that action. So they all adopt whatever distance seems appropriate for that local circumstance.
3. Peregrines are increasing or stable in most of the West. But they require pretty specific conditions to successfully nest. Giving up a little cliff space for successful pairs seems like a reasonable thing to ask from climbers.
No such excitement Paul. No, I am just old, fat, and had ACL replacement, been as busy as shit saving the world, and bought a retirement farm assuming I live long enough to retire.
Muffster, hugs and kisses. 8D
