Question

William Dilger studied the nest-building behavior of parakeets of the genus Agapornis. He crossed members of a species that carries nest-building material in its beak with members of a species that carries nest-building materials tucked under the tail feathers and observed the behavior of the hybrid offspring. These offspring showed hybrid behavior and usually dropped the material whether they carried it in their beaks or under their feathers. One particular bird tried to build a nest 48 times and failed. On the next try, it was successful. What docs this tell you about whether nest-building in this genus is innate or learned?
