The average lifespan of the tasmanian devil is anywhere between seven and eight years. The Devil feeds on small birds, reptiles, amphibians, insects and the dead livestock. The devil is also nocturnal and only hunts at night. It sleeps in its den during the day. It roams about 16 km from its den which is a great distance for a small animal like this. Young devils can also climb trees. Devils were a nuisance to the early European settlers of Hobart Town, raiding the poultry yards, but were soon driven away to more remote areas of the island. In 1830 the Van Diemen's Land Co. introduced a bounty scheme to remove devils, as well as Tasmanian tigers and wild dogs, from their northwest properties: 2/6 (25 cents) for male devils and 3/6 (35 cents) for females. Devils ate animals caught in snares, and were believed to take lambs and sheep. For over a century they were trapped and poisoned and became very rare.
