Detroit Zoo - (no signage at the exhibit that identifies this bird) - July, 2016

I think this might be a blue-bellied roller. This species is unmistakable if you see it in flight, because it has beautiful wings with rich blue flight feathers contrasting with paler blue upper and lower wing coverts.

I think so too, gentle lemur. It's just odd that there's no signage for this bird.

What a good photo.
