Glenn R. Stewart of the Santa Cruz Predatory Bird Research Group will discuss the peregrine population recovery, and falcons in a changing world, and will bring a live falcon to this event. Falcons that once nested in remote cliffs are now nesting in cities on man-made structures such as buildings and bridges. In 1970 there were only two known nesting pairs of peregrines in California; today the population has recovered to over 250 known nesting pairs, including several in the Bay Area. Co-sponsored by the Business Science and Technology Center and the Wallace Stegner Environmental Center. This is a Green Stacks Program.
