The kea (Nestor notabilis) is an omnivorous parrot native to the alpine regions of New Zealand. While most parrots primarily consume plant materials such as seeds, fruits, and roots, the kea is known for its opportunistic feeding habits.12

The kea feeds on sheep carcasses and carrion as a source of nutrition. Additionally, these birds have been observed attacking sheep that are already sick, injured, or trapped, though they rarely target healthy individuals. This behavior reflects the species' highly curious and adaptable nature, which allows it to exploit various food sources within its mountain habitat.21
