| Abstract: | Summary.* 1Parent Coot treat all young conspicuously unlike their own as territorial intruders. * 2Parents with young less than two weeks old will tolerate, feed and brood young similar in appearance to their own. Three cases of permanent adoption are recorded. * 3Parents with young much over a fortnight old will not tolerate any strange chicks, however similar. This appears to prove that they recognize their own young individually. * 4The reactions of the young are controlled by releasers. Two are cited, viz. releasers of the following, and alarm, reactions. * 5Chicks up to at least eight hours old will follow men, accept food from (hem, and respond to calls made by them. * 6This tameness disappears by the second day (except in the case of hand-reared young). Imprinting is by then complete. * 7At first young will follow and beg from any adult Coot. * 8At 8–11 days young learn to avoid adults in an attitude of attack. * 9Individual recognition of adults develops at about three weeks. |
