Frank Cousins, age 10, of Providence, R.I., for his question:

IS THE MONGOOSE A BIRD?

The mongoose is not a goose and it is definitely not a bird. A mongoose is a ferret like carnivore that lives in Africa and southern Asia, it is related to the civet and the genet.

The common mongoose is about 16 inches long and has stiff, yellowish gray hair that is grizzled with brownish black. It has a fierce disposition but it can be tamed.

The mongoose is known for its ability to kill mice, rats and snakes. It is not immune to poison, but its swiftness allows it to seize and kill poisonous snakes such as the cobra.

Some time ago the mongoose was introduced into Jamaica, Cuba, Puerto Rico, Hawaii and other parts of the world to destroy hordes of rats. But the mongoose also kills poultry, wild birds and other beneficial small animals. It eats birds' eggs and young birds and it reproduces rapidly.

Mongooses cannot be brought into the United States without a permit from the Bureau of Sport Fisheries and Wildlife. A permit is granted only if the animal will be used in a zoological exhibit or for educational, medical or scientific purposes.
