2.25 Interval Music 2.30 Biology in the Service of Man The Animal Mind ' How Animals communicate with one another' H. MUNRO Fox, F.R.S. Animals communicate with one another not only by sounds, but also by movements of face or body, and by smells. It is especially important for animals living together in herds or flocks to be able to communicate. Birds migrating at night keep together by cries, deer and dogs communicate by smells. Bees communicate by dance and by scent. This is an instinct. The noises of apes and many bird cries are also instincts, but birds learn part of their songs. This is an outline of this term's last biology talk which Munro Fox is to give today. (From Midland)
