In my region in the state of São Paulo, even though I can find these fellows quite easily too, I never get them in the open.
Apparently that's not the case in the state of Goiás haha. I found them in the open, in the sun light, all the time there. The motmots there are not shy.
Sadly most of the time when you see them in the open like this there will be urban elements in your shot. But still, the shots are very worth it cause the light hitting these beauties make them even more amazing.
