Wing-shaking and wing-patch as nestling begging strategies: their importance and evolutionary origins.

Original language description

Avian chicks use different begging strategies when soliciting parental care. A novel begging strategy was recently observed in Horsfield?s hawk cuckoo Hierococcyx hyperythrus (=Cuculus fugax). Chicks of this brood-parasitic species raise and shake theirwings and display to fosterers a gape-coloured patch on the undersides of their wings. Although the gape-coloured wing-patch may be a unique trait of Horsfield's hawk-cuckoo, wing-shaking in the context of begging is virtually universal in both brood parasites and their hosts. A simple qualitative comparison across different avian taxa suggests that wing-shake begging is most probably an ancestral feature of cuckoos and perhaps all altricial birds. The wing-shaking may be an honest signal of chick quality. It could also reduce the risk of predation if wing-shaking was coupled with reduced loudness of begging. Horsfield's hawk-cuckoo chicks could have exploited the universal pre-existing host responsiveness to wing-shake begging. Evoluti
