South America has some weird birds. One of the stranger ones is the Hoatzin.
Ornithologists squabble over the origins of this species, but you don’t have to be a scientist to see that this bird hasn’t evolved very far beyond the dinosaurs. Most ornithologists seem to agree it is the sole surviving species of an entire family that broke away from the dinosaur lineage about 60 million years ago. Right after the mass extinction of the dinosaurs.
Hoatzin are pretty common in the Amazon basin. Noisy, slow-moving, seriously stinky and poor fliers, you smell them and hear them before you see them.
