DALLAS THE DOG TEAMS UP WITH MAGPIES TO FIGHT COCKATOOS Colleague Jeremy Zakis. Zakisrecounts how his dog, Dallas, successfully chased destructive cockatoos off their property. While usually friendly, Dallasidentified the birds as enemies, aided by territorial magpies that swooped in to drive the cockatoos away. Although cockatoos are often considered pests that raid trash bins and damage homes in New South Wales, Dallas's vigilance has protected Zakis's yard, forcing the birds to target the neighbor's roof instead.
