Costa Rica day 11 Posted on Sat, 7th Mar 2015 by Robin Last full day. All the trips are in small boats among the mangroves. Tomorrow we travel back to San Jose. This allows you to get really close to birds. This is a Sungrebe. This is an Agami heron. Even our local guide was amazed at the views we got. Male anhinga have a blue eye. Always look up for Magnificent Frigatebird. These are Spectacled Caiman and Owl Butterfly.
