ALISON GREGGOR: So as part of the corvid family, the Hawaiian crow is known to be one of the more intelligent birds of the Hawaiian Islands. “The quality of this assembly places it among the very best avian genomes assembled to date, comparable to intensively studied model systems,” according to a post on the UH Hilo Biology Department News. MyUH The research describes the high-quality reference genome that was generated to assist recovery efforts for the ʻalalā. Fish and Wildlife Services. The ‘Alalā, or Hawaiian Crow, has been extinct in the wild since 2002, preserved only at the Keauhou and Maui Bird Conservation Centers managed by San Diego Zoo Global’s Hawai‘i Endangered Bird Conservation Program.

Otherwise it would be near impossible to find a bird in a big forest. In those Hawaiian islands, birds would have found a multitude of microclimates, a lack of most predators, and a pretty safe spot to grow and evolve—which they did, diversifying into a wide range of species, each suited to a different lifestyle and habitat. So any release program that is starting up– there’s a lot to learn.
