Here are the Best Liars in the Animal Kingdom

Nature is brutal, and some creatures have evolved their own sneaky ways of surviving, from mimicking other animals to taking advantage of dutiful parents.

Weird Animal Question of the Week decided to take an honest look at various strategies animals use to deceive each other.

Blue Jay

Birds are among nature’s most gifted liars. For instance, “blue jays do a good job of imitating a variety of hawk species,” says Bob Mulvihill, an ornithologist at the National Aviary in Pittsburgh. (Read about why we lie in the new issue of National Geographic magazine.)

The supposed “hawk” causes other birds to scatter, leaving the jays with sole access to bird feeders—and thus an easy meal.


North America’s cowbirds produce up to 40 eggs a season, and instead of making their own nests, females sneaks them into other birds’ nests.

“They’re the quintessential bird that does not put all their eggs in one basket,” Mulvihill says. (See “How Snakes, Spiders, and Other Predators Fool Their Prey.”)

Though some bird species drive off cowbirds, the endangered Kirtland’s warbler is usually tricked into raising the cowbird babies as its own, a phenomenon called kleptoparasitism.

This is so common and taxing to the adult warblers that it’s a major reason why the warblers’ have declined, Mulvihill says.

Eastern Gray Squirrel

Eastern gray squirrels of North America will hold a nut in their teeth and pretend to bury it in a variety of places before actually doing so, a tactic to keep other squirrel thieves guessing, according to the National Wildlife Federation.

Any would-be nut bandits then dig up a lot of empty caches before giving up.

Another squirrelly maneuver is to bury a nut and then pile leaves and dirt over another spot that looks like a food cache, but is actually empty.
