I was lucky to receive a cook's tour at feeding hour (actually feeding is most of the day but not at night for the upcoming baby bird rescue season). Feeding of raptors is not for the meek (some eat chicken but most prefer dead mice, guinea pigs and quail when available). I saw the smallest owl (screech) to the larger owl (barn) plus the smallest hawk (kestrel) to the larger hawk (red tailed) to a very large golden eagle. The absolute treat was to watch Miss Liberty, a wing damaged Bald Eagle, up close but at a respectable distance. Liberty Wildlife has been rescuing birds of prey for over twenty years and tries to release as many as possible back into the wild. Liberty Wildlife has plans to move to larger facilities at the Phoenix Zoo where it can take care of more birds plus other critters and reptiles. I urge yelpers to help out any way they can.
