BioNB 2210: Lecture 11 Sept. 19, 2011 Lecture 11: How Bees Find Their Way Professor Thomas Seeley Learning Objectives 1. To understand the four basic methods that animals, including humans, use to solve the problem of finding their way to a particular location: bean orientation, piloting, dead reckoning, and true navigation. 2. To understand the experimental evidence that shows that bees can perform piloting. 3. To understand the experimental evidence that shows that bees have the three tools needed for performing dead reckoning: a compass (= time-compensated sun compass), an odometer (using optical flow), and a means of path integration. 4. To understand the experimental evidence that shows that bees are not able to perform true navigation (map and compass orientation). 1. The PROBLEM: a foraging bee must find her way to and from patches of flowers 1000’s of meters (several miles!!!) from home. 2. Possible solutions to the problem:
