@dianea @faoluin The way it was described to me many years ago was:
Birds are not particularly intelligent. Once you take out the feathers and the huge eyes, there is not much volume left for a brain.
But corvids and parrots are quite intelligent.
Therefore, they are not birds.
Instead, the only logical possibility is that they are the survivors of a crashed alien spaceship.
The engineers became corvids, having dark plumage perfect for working with oily machinery, and mechanical problem solving skills. The bridge officers became parrots, with brightly coloured uniforms and ability to communicate in alien (to them, i.e. human) languages.
