Distraction displays were once considered to be a sort of “partial paralysis,” or uncontrolled, stress-induced movements. On the basis of several observations, David Lack postulated that such displays simply resulted from the bird’s alarm at having been flushed from the nest and had no decoy purpose. Other researchers, including Edward Allworthy Armstrong, have taken issue with these arguments. Armstrong additionally noted that displaying animals were rarely captured by predators, as would be expected if the display were truly uncontrolled, and that the movements seemed to show signs of some sort of control by the animal, although likely not conscious, intelligent control. One example of apparent control is attention seemingly paid to routes used by the displaying animal when moving away from the nest.

An additional hypothesis in alignment with Armstrong’s ideas about conflicting impulses suggests that the incorporation of sexual and threat displays into the distraction display may represent displacement. Displacement occurs when an animal, unable to satisfy two conflicting impulses, may initiate an out-of-context behavior to “vent”. In any case, there are some forms of distraction display which may in fact have evolved from stress responses, an idea more in alignment with Lack’s hypothesis. One of these is the “rodent-run” display, in which a bird fluffs its feathers to mimic the fur of a rodent and scurries away from the nest. It is possible that this display originates from a feather ruffling reflex to alarm. There are several conditions in which distraction display may be advantageous to the animal, such that the incorporation of displacement or stress behaviors into offspring defense will most likely undergo positive selection.

Most such cases depend upon the condition or location of the nest: distraction display has tended to evolve in species whose nests alone do not provide a substantial physical barrier to predators, and in those that nest on exposed terrain or close to the ground.
