About These Birds
Laughing Kookaburra
The laughing kookaburra is the largest kingfisher in the world, famous for its raucous laughing call that has become an iconic sound of the Australian bush. Despite being a kingfisher, it rarely eats fish, preferring terrestrial prey. Family groups perform chorus calls at dawn and dusk to mark their territory.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
