The Mauritius kestrel and the echo parakeet were two of the rarest birds in the world, but after decades of conservation efforts, they’re now making a comeback: just a few surviving individuals have turned into hundreds. And while these birds are only found in Black River Gorges National Park in Mauritius, the dedicated efforts to bring them back from the brink is a hopeful example for the world, showing us that it’s never too late to act.
