හාවා[Hawa]/Black-naped Hare/Indian Hare (Lepus nigricollis)



Black-naped Hare is well distributed in scrub and grasslands throughout the island. It is nocturnal in habit in most areas and during day time lies up in a well camouflaged sheltered patch in the undergrowth. But in the protected areas such as in national parks, it is active even during the day time, mostly in the morning hours. Black-naped Hare is an almost entirely herbivorous mammal and feeds on grasses, shoots, young leaves etc. It doesn't have definite breeding season and produces one or two young ‘leverets’ at any time of the year.
