Though not technically a zoo, I visited the Boise, Idaho based Peregrine Fund's World Center for Birds of Prey this last weekend. They have a nice little visitor center that serves as a museum and display of live birds. The Peregrine Fund operates California Condor and Aplomado falcon breeding facilities at the center. The breeding facilities are obviously not open to the public, but they do have individuals of both species on show along with several other fascinating bird species. You enter through a small gift shop, with a very impressive book selection. Outside the gift shop is a small courtyard with 4 raptor sheds that house a bald eagle, an ornate hawk-eagle, an aplomado falcon, and a bateleur eagle. They have a large lawn space where at certain times of year they have free-flight demonstrations. Another corner of this courtyard will soon go to a display of non-breeding California condors next spring. You then enter the main building which is really a museum of sorts. Live raptor presentations happen within, and there are films and displays talking about raptor biology and the various programs operated by the Peregrine Fund. At the back of this building is a set of indoor raptor rooms that are viewed from a darkened hallway through tiny windows. These used to be breeding facilities, but now house a turkey vulture, an Eurasian eagle-owl, an aplomado falcon, and the highlight, a female harpy eagle. Harpy eagles were formerly bred at the center, but that breeding program was relocated a little closer to home in Panama. A fifth birdroom is closed off from viewing and used to hold California condors, but is now used for training raptors for flight since the condors will soon be on display elsewhere. On the site they also maintain an enormous research library and an archive of falconry. The research library is closed to the general public, gut the falconry archives are available for tours if booked in advance. All in all, a very fascinating place to learn about real-world conservation.
