Bees can combine range and visual angle to estimate absolute size

Horridge, George Adrian; Zhang, S. W.; Lehrer, M.


Previous work has shown that bees can discriminate objects viewed on a vertical plane on the basis of angular size, as well as objects on a horizontal plane on the basis of range. In the present study, we first demonstrate the bees’ ability to measure range to a vertical surface, and discriminate angular subtense to objects on a horizontal plane. The question whether they can combine the independent measurements of angular size and range to infer the absolute size of an object is then examined...[Show more]
