I was woken every morning to the sound of Howler Monkeys but never had a chance to see them. I did, however, see the othe two species in the park. The highly endangered Squirrel Monkery and the White-headed Capuchin Monkey. Our guide, Henry, was able to call in the Squirrel Monkeys, or Mono Titi, as they’re locally called through some squeaks he made. There’s perhaps less than 1500 of these tiny primates left and exist only in two disconnected National Parks in Costa Rica: Manuel Antonio and Corcovado National Park. Both now islands in a sea of development and agriculture.
