The Crazy Cuckoos are enemy guards encountered in the level Bio-Ray Isle in the game Sly Cooper: The Thief Returns. They serve as rooftop guards.


These cuckoo clock birds have a green head with a brown body, red tail feathers, purple wings and a yellow beak and feet. They don't wear anything but can somehow create tremors with their sounds. They can call other guards by squawking.


When close, they ram you, when near, they stomp the ground creating a fissure, when far or unreachable, they shoot a rock at you. When feelings in danger, they'll cuckoo loudly alerting other guards.


  • These guards are based on the Earth element.
  • They take 6 hits to defeat.
  • The Cuckoo Birds apparently have a South American accent and are said to be transferred from Brazil.
