"A hummingbird picks up more than nectar at a flower in Costa Rica's Monteverde Cloud Forest Preserve. Pinhole-size mites live in the blossom. When the plant's last florets bloom, mites wait for a bird's bill to enter, then climb on and sprint to the bird's nostril at cheetah-like speed—12 body lengths per second. The stowaways cling till they smell the familiar perfume of a new host plant, then deplane."
