Cockatoos Confirmed as Structural Vandals; Magpie Invites Itself Inside. Jeremy Zakis discusses how the destructive behavior of cockatoos is confirmed as they pulled so many nails from a neighbor's iron roof that the structure is now drooping, necessitating expensive, specialized repairs. Cockatoos are described as "pure evil with wings" and are known for tearing up building structures. Conversely, Dallas the poodle's friends, the magpies, are growing bolder. One teenage magpie walked four feet into Jeremy's kitchen and calmly listened to him before eventually walking back out. Australian magpies are even said to have a unique, twangy "Australian accent."
