My experience took my ideas about society, science and nature, and developed them into something that has been vital to my education and development as a person. It was great experience and I made some amazing friends. There are lots of projects going on in a variety of area in ecology at any given time. I spent about 9 weeks there and helped out with: small mammal surveys, bat catching, insect biodiversity surveys, birding, and a number of other things. My experience in Paraguay opened up a lot of doors for me later on. The next summer I was able to get a paid internship at STRI working in Panama.
