Most folks, even advanced "birders", do not know that Mendocino County has more nesting pair of Peregrine Falcons than any other county in the 48 contiguous states.  During the intensive survey work of the 1980s, when the species was federally listed as endangered, Mendocino County had over 20 of the known 60-or-so nest locations in California.  From the uppermost elevations of the UC Hopland Research & Extension Center I can point out five Peregrine Falcon nest locations, all which have been simultaneously active in certain years.  All of these are in a 10-mile diameter area.... probably the most dense nesting group anywhere in North America.

This morning an injured immature bird was rescued from the lower portion of the Center.  It appears to have minor wing damage, and I suspect that the cause was a collision with a power line.   The bird is in transport to The Bird Rescue Center of Sonoma County as I post this.   Hopefully the outcome will be good ... and the bird can be released back into the wild in the near future.
