MaNi Leave a comment

The Striated Caracara can solve problems just as much as Cockatoos can, reports the New Scientist magazine in November 2023 about a study at the Messerli Research Institute at the University of Veterinary Medicine Vienna in Austria. The Johnny Rook Project was conducted in collaboration with the Institute of Marine and Coastal Research at the National University of Mar del Plata in Argentina and the Austral Scientific Research Centre in Ushuaia in Argentina. It was funded by the Austrian Science Fund.

Researchers at the Comparative Cognition Unit at the University of Veterinary Medicine (VetMedUni) Vienna, led by cognitive ecologist Katie Harrington, conducted studies on the problem-solving skills of the Striated Caracara in the Falkland Islands.

What is falconry? 

Falconry is the tradition of hunting with birds of prey, or raptors. It is called falconry because the birds are in the Falconidae family, which includes all birds of prey that kill their prey with their sharp beaks.

Birds in the Falconidae family include falcons, gyrfalcons, hobbies, kestrels, and merlins.

Other birds of prey are also trained, such as those in the Accipitridae family, including eagles, goshawks, and hawks. Accipiters kill their prey with their feet, by swooping on their prey and killing it with their sharp claws, called talons.
