Comparative psychologists Vs. Ethologists

If i am a comparative psychologist, I am working in a lab setting with controlled experiments. I am generally interested in the “how’s” of learning, in other words, proximate questions based on the genetics and development which influence behavior in animals. The type of experiment I might be conducting would be with rats and pigeons in the lab. I would be testing their learning abilities and working with BF Skinner. I believe that animals are born with a blank slate based on my studies

If I am an ethologist, I am in a field setting observing nature. I am interested in the evolutionary history and the “why’s” of behavior, in other words, ultimate questions wondering about their evolutionary history and adaptive value. I might be in the field observing why spiders live in groups and trying to understand the value of that behavior with Konrad Lorenz and Niko Tinbergen.
