Evolution on islands can produce unusually large species. Haast’s Eagle lived on the islands now known as New Zealand. With a wingspan of 9 feet and weighing up to 30 pounds, the eagle hunted the moa — a flightless bird that stood over ten feet tall. The eagles probably vanished not long after their moa prey went extinct, about 500 to 600 years ago. A site called the Cave of the Eagle contains Maori paintings of Haast’s Eagles, preserving the legacy of this immense raptor. Learn more at BirdNote.org.
