The house sparrow is the world's most widely distributed bird and is still extending its range; it arrived in Iceland during the 1990s. What's more, this gregarious little species leads a life that HBO really ought to film as a reality series. According to Wikipedia, although males and females mate for life, "bigamy occurs, and is mostly limited by aggression between females. Male House Sparrows guard their mates carefully before breeding to avoid being cuckolded."
