Hello!
I recently visited the Jardim Botanico de Porto Alegre in Brazil, and I saw this nest up in a tree there. It’s about two feet tall. I’ve looked up both insect and bird nests, and I can’t seem to find a visual match online. It has thorns on it, and there weren’t any other structures like it anywhere, so I don’t think it’s a feature of the tree itself.

What's That Nest???

Dear Brynna,
This nest appears to be made of mud and it appears that it is quite large.  We wish you had estimated its dimensions.  Like you, we would speculate that it was created either by a social insect or a bird.  Our initial search did not produce any results.  Perhaps our Brazilian counterpart, Cesar Crash of Insetologia will have some ideas.

Thanks to a comment from a reader, we were directed to this image of a Paper Wasp Nest on FlickR.
