I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.
Explanation:
The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.
Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.
