Howler Monkeys are very difficult to photograph. Always dark faces and a camera pointed up at the sky. I am pretty proud of these two shots from 4-5 feet away. You have to get close and at the monkeys level for good pics. Especially with just an iPhone.
I really love catching the facial expressions up close. Of all the attempts at fotos de monos, these two are my favorite.
This is more typical of the shots I can get. Pretty cool seeing monkeys all the time. I love this place!
