I was excited to see these guys at the National Aviary, but looking through my photostack, I see I didn't even bother to take a picture. Up in the tree, it just looked like a black pigeon. 😐
The colors are an effect of refraction, so seeing them in a canopy takes that away. If you go scrolling pics of them, you'll see they're almost all really sunny photos.
Apparently, the dodo was not according to the reports of sailors. On the other hand, people used to eat a huge number of doves in the middle ages, to the point that they built towers called dovecotes to keep them in. So who knows?
