Becoming a bird ecologist was just luck! I had the chance to be a field assistant for a scientist working in the Galapagos Islands, and while I was there, I saw a particular problem in behavioral biology that I wanted to solve and, in the process, made myself into a bird ecologist.
There are two things I enjoy most about my work. First, I get to work with interesting and enthusiastic people who are also fired up about science. Second, every once in a while I have moments in which I suddenly understand the solution to a problem that I've been working on - those are great moments.
