The Sword Billed Hummingbird is holding down the genus Ensifera as the only living member. It's noted for its exceptionally long bill which can reach 4 inches long. In comparison, the common Ruby-throated Hummingbird only reaches 3 inches in length - beak and body combined!
Water chevrotains are, except for during the mating season, solitary animals. Their small size makes them fairly easy prey for a number of predators; when threatened the chevrotain either stands motionless amongst vegetation, or can dive into water. As its name suggests, it is capable in water, but can only swim for short periods before tiring.
