The Nilgiri marten (Martes gwatkinsii) is the only species of marten found in southern India. It occurs in the hills of the Nilgiris and parts of the Western Ghats.
It is about 55 to 65 cm long from head to vent and has a tail of 40 to 45 cm. It weighs about 2.1 kg.
Very little is known about the Nilgiri marten. It is diurnal, and though arboreal, descends to the ground occasionally. It is reported to prey on birds, small mammals and insects such as cicadas.
Its so rare that only few people(40-50) in the world would have witnessed them and Im very lucky to not only have witnessed them but to photograph them.
