In the same year Konrad Lorenz, Niko Tinbergen and Carl Von Frisch jointly won the Nobel Prize in medicine for their pioneering work in animal behavior, the Israeli behaviorist, Amotz Zahavi, hypothesized that some birds aggregate in roosts to share information on locations of profitable food sources. Lorenz shared the Nobel prize, in part, for his work on imprinting: a phenomenon where hatchling birds immediately accept as parents the first object they see upon hatching (often Lorenz himself). In comparison, Zahavi’s ideas about the function of bird roosts, if correct, meant that some birds have much greater mental abilities.
