the zone-tailed hawk has been suggested to mimic turkey vultures, most obviously in their flight pattern: the hawks fly unusually with wings raised dihedrally, and will rock back and forth in a similar manner to turkey vultures. additionally, the silhouette and the shape of the flight feathers resemble a turkey vulture much more than other similar hawks. this is an example of aggressive mimicry, since turkey vultures rarely hunt animals, while the zone-tailed hawk is an active predator. its prey will be more likely to ignore the presence of the bird, believing it to be a harmless scavenger. the kettling behaviour of turkey vultures aids the zone-tailed hawk, as it can blend into large gatherings of vultures. although up close the two animals are very different, even experienced birders may have difficulty identifying a zone-tailed hawk from its deceitful silhouette and flight pattern.

the mimic poison frog, also known as the poison arrow frog or imitating poison frog, is notable for having many colour morphs that allow it to mimic multiple different species. the four different mimicking morphs are:

'varadero', which mimics the red-headed poison frog, ranitomeya fantastica

'striped', which mimics the lowland zimmerman's poison frog, ranitomeya variabilis

'spotted', which mimics the highland zimmerman's poison frog, ranitomeya variabilis

and 'banded', which mimics the summers' poison frog, ranitomeya summersi

the mimicry is used defensively, as this species, while toxic, is much less so than the species it mimics.
