In more distant species from us, researchers have found similar evidence of females mating with multiple males. Many birds that were thought to be monogamous have turned out not to be. Female bluebirds have been spotted flying considerable distances at night just to mate with other males. Data on the small-mouthed salamander, bush crickets, yellow-pine chipmunks, prairie dogs and mealworm beetles have shown that the females of all these species, too, enjoy more reproductive success when they mate with more males.
