We the boarded a boat and went piranha fishing. We saw quite a few birds en route. Black crested nun bird, Swallow wing, Roadside hawk, Hoaezin, Black collared hawk, White headed tyrant, Amazon kingfisher, Ringed kingfisher, yellow headed blackbird
We went up a small creek and most everyone but me caught a piranha. They just ate the bait off my hook. So I quite and took pictures instead.
On the way back up the river we stopped at a shallow area on the side of the river to see dolphins. There were both gray and pink ones swimming around us.
