It's great that you're interested in studying Ethology! The link that Wael posted is really helpful!
Additionally, I have a friend at University of California Davis who raves about their animal behavior program! She says that she has the opportunity to interact/to study animals every morning (6 am) on campus, accompanied by professors, just a short bike ride away from her dorm room!
Depending on what type of job/career path you hope to take with your degree, each school on the list definitely has its positives and negatives. Things to think about: are you interested in doing more hands on work with animals, or would you prefer doing more distant research? Or both perhaps?
Let me know if I can be of any additional assistance!
