I really loved it in the lowlands - as difficult as I found the photography there due to the low levels and high canopy, I can't wait to get back there as soon as I can. Here are a few photos that I've taken there so far.
For a couple of weeks I spent most days down one particular trail near the river as pretty much every time I would see the same troops of Peruvian spider monkeys. On this occasion I just managed a photo before it disappeared.
I also spent quite a bit of time up the 60m canopy tower. One evening a group of White-bellied Parrots flew into a castaña tree near the tower, just as the sun was about to dip below the horizon. It wasn't close enough to fill the frame so instead I decided to show some of the castañas on the tree. The colours looked great in the evening sun.
