Great guide for birdwatching in Soberiana NP near Rainforest Discovery Center. Agreed to pickup at 5 am. With sunrise at the park and first on top of the observation tower. We saw many birds and howler monkeys in the far distance. Later a walk along Pipeline Road. Worried about availability of food and drinks, but no shortage and expectations exceeded. Mario is knowledgeable and good at spotting birds. Brought our own binoculars, but his telescope showed the birds in even higher detail and brightness.
