The Numidid are an avian species with remarkable similarities to the Terran guinea fowl. They appear in the novel The Amity Incident.
They have a culture that praises rationality and views scientists as dangerously insane. And, in some cases, they might have a point.
It wasn't until the Numidid met another, more insane species on the planet Amity that they began to learn how valuable science truly was.
