The species mentioned herein teach us that. I saw my first nene at Slimbridge, a successful captive breeding facility in England, a world away from their homes in the Hawaiian Islands. The nene I remember most were wild ones—a small flock that descended through the mist as I hiked across Haleakala on Maui. They landed in front of me as grey fog gave way to brilliant blue skies and revealed the surreal purples, yellows, and browns of the caldera. Wild, remote, beautiful—and how can anything live in such a strange place?
These exotic plants, which quickly dominate an ecosystem once they’re established, choked out the saplings of native tree species, preventing the forest from regenerating properly. Over time, the trees the echo parakeet depended on for sustenance began to disappear. It wasn’t possible for the bird to simply switch to eating the weeds, since they didn’t fruit during its breeding season, when an ample supply of food is critical for feeding hungry nestlings. Virtually no chicks were fledged between the 1970s and the mid-1980s, when the population had reached rock bottom.
Here’s some proof: if you added together the populations of the Mauritius kestrel, the pink pigeon, and the echo parakeet just a few decades ago, you would have come up a number of less than 35. Thirty-five.
