පොදු ගේ මීයා/Black Rat/Common House Rat (Rattus rattus)

 A very common large rat distributed throughout the island as five sub species. It inhabits areas near human habitation because of the availability of food from household wastes. But it is not uncommon in jungles and open country. It is an omnivorous and mainly feeds on grains and vegetable matters, but also eat meats, dried fish, etc. as well as eggs rob from nests of birds when available. Common House Rat is one of the most prolific mammal and normally a female which commences to breed when she is about 5 to 6 months of age, produces 4 to 5 families each year, each family numbering 3 or 4 young ones, but some time as many as 8. The nest is a collection of grass, straw, fibers, pieces of rags or paper or any other suitable materials gathered together and secreted in some convenient spot such as beneath a rock, log or the root of a tree or if in a building, in or behind a box or in some dark corner in the roof. It is a good climber as well as a swimmer. Common House Rat is usually a solitary mammal except during the breeding season, though sometime several of them can be seen in garbage dumps and such other places where its foods are abundant. It is normally active during the night though sometime can be observed even during the day time if it is undisturbed.
