Bundala is a massive natural preserve that can only be toured by arranging for a guided safari. Details about the park, and how to arrange a tour, can be found here. There are pictures of monkeys and elephants to be found on the birds and turtle site, but in this post I will just describe some of the birds.
It was a four hour guided safari in a jeep. The guides were very knowledgeable, and pointed out many species. We had our bird book and dad was busy recording the species in the book as we toured the area.
