Fairy-wrens, wasps, and a nearly 3,000 year old big toe
You'll Be Safer With Me
Male splendid fairy-wrens sing a special song when they hear the call of a butcherbird, their predator. The behavior would seem to paint a target on the fairy-wren. But University of Chicago scientists report the males are actually issuing a mating call. They are choosing a moment when fearful females are most attentive, the researchers found. The effect may be like that of a scary movie on humans, in which fear brings a date closer.
