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.
One evening while looking for the monkeys I saw this Spot-breasted Woodpecker to the side of the trail. Luckily it was nice and open so the light levels were much higher than normal, and most of the background was covered by trees, leaving no big white gaps in it!
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.
One of the birds I saw very frequently was this one, the Black-fronted Nunbird. They would perch up on fairly exposed branches before swooping down to the ground to catch caterpillars or, in this case, a katydid.
I also had a chance to go out on one of the oxbow lakes, where one of the most common birds was the Red-capped Cardinal with its crimson head.
That's all for this post; I'll try and do another one within the next few days with some more pictures.
