Get an up-close look with wildlife photographer Joel Sartore at the Cook Strait giant wētā and the kākāpō, two endangered species in New Zealand, and examine why behavioral adaptations no longer protect them, in this video from RARE—Creatures of the Photo Ark. While their ancestors flew, both the giant wētā (a large insect) and kākāpō (a parrot) evolved to be flightless and inhabit the forest floor. Because New Zealand lacked predatory land mammals for millions of years before humans settled there, these species thrived. However, over the past thousand years, invasive species have driven giant wētā and kākāpō populations close to extinction. This resource is part of the RARE–Creatures of the Photo Ark Collection.
