Cannomys badius
lesser bamboo rat

Cannomys badius is found in Nepal, northern and eastern Bangladesh, northern Cambodia, northern Vietnam, Bhutan, Assam, southwestern Yunnan, Burma, Thailand, and Laos (Nowak, 1999).

Cannomys badius inhabit thicket and bamboo forests and hilly mountainous regions (Anderson, 1984) and are sometimes found at high elevations (Grzimek, 1975).

Body length of Cannomys badius is 6.4 to 18 inches (Grzimek, 1990). Commonly called the lesser bamboo rat, it has small ears and eyes and greatly resembles the American poket gopher, except in its lack of cheek pouches. C. badius has thick fur on its head and body with less fur on its tail. This mammal ranges in color from reddish cinnamon and chesnut brown to ashy gray and plumbeous. Some individuals possess a white band on the top of the head and a narrower band from the chin to throat (Nowak, 1999).

Cannomys badius is a medium sized mammal with short, powerful legs (Anderson, 1984). They posses long, powerful digging claws and smooth pads on the soles of the feet (Nowak, 1999). C. badius have large incisors and molars that have flat crowns and roots (Grzimek, 1975). The zygomatic arch is very wide and the body is thick and heavy. Female lesser bamboo rats have two pectoral and two abdominal pairs of mammae (Nowak, 1999).

Lesser bamboo rats leave their burrow in the evening to consume vegetation. When studied in captivity, activity reached its peak in the early morning or evening and they slept a great deal throughout most of the day. These mammals dig burrows in grassy areas, forests, and gardens (Nowak, 1999). Digging is done not only with their powerful feet but also with the help of their large incisors (Grzimek, 1990). An individual may construct several burrows but will only inhabit one (Grzimek, 1975). The tunnels constructed are simple and include a multipurpose nesting chamber (Anderson, 1984). Tunnels are often very deep. Lesser bamboo rats move slowly when above ground and are said to be fearless when an enemy approaches (Nowak, 1999).

C. badius eats mostly bamboo roots and shoots but also consume shrubs, young shoots of grasses and other roots, and will eat seeds and fruits (Anderson, 1984, Grzimek,1990).

C. badius will inhabit tea gardens and construct burrows and tunnel systems in them, damaging these crops (Nowak, 1999).

Cannomys badius is important to many tribes in the Burmese hills. These tribes hunt the lesser bamboo rat for food (Nowak, 1999).
