Following an alarming decline during the 1950s and 1960s, this spectacular falcon, also called the "Duck Hawk," is on the increase again, now that pesticides that caused thinning of eggshells have been banned. After an intensive program of rearing birds in captivity and releasing them in the wild (a process called "hacking"), this large falcon is reclaiming nesting grounds from which it disappeared a few decades ago. A favorite nesting site nowadays is a tall building or bridge in a city; these urban Peregrines subsist mainly on pigeons.
