摘 要：Rapid learning in the young of most endothermic animals can be expected to be favored by natural selection because early independence reduces the period of *** of comparatively slow juvenile development continue,therefore,to attract scientific *** most species of birds,including raptors,the young depend on their parents for some time after fledging for the provisioning of food and for protection while they learn to become nutritionally and otherwise *** raptors,post-fledging dependence periods that exceed 6 months are exclusive to the largest species and these have reproductive cycles that exceed 12 *** contrast,young of the medium-sized grey falcon Falco hypoleucos have been reported in close company with their parents up to 12 months after fledging,that is,at a time when the adults are expected to breed *** investigated the occurrence and characteristics of prolonged adult–juvenile association relative to other falcons and similar-sized *** found that the behavioral development of grey falcon young is extremely delayed,and that they even depend nutritionally on their parents for up to 12 months after *** suggest that these 2 distinctive features are,ultimately,adaptations of the grey falcon to its extreme environment,Australia’s arid and semi-arid zone,one of the hottest environments in the world.
