I have an announcement to make before we start class. I’m looking for a student to hire as a part-time assistant. I’m interested in someone who has at least two semesters’ experience in behavioral biology. I’m studying pigeons and their methods of navigation. So I need someone who is comfortable working with birds. Even though most d the work involves research, I also expect some help in cleaning cages and feeding the binds. I’ll need someone for about two hours daily, including Saturday. If you are interested, please some to see me fight after today’s class.
