Help ID Brazilian bird?

I was walking at a park yesterday in Curitiba, southern Brazil, when this guy decided to have a succulent meal 3 feet from me.
Would love to know what it is.

Thank you!

Nice shots, looks like a Rufous hornero, they build incredible mud nests.

Thank you, Joe!

It does look like one.
I also have a shot of this nest from the same walk.
