Greater Cane Rat (
Thryonomys swinderianus)
Habitats and Ecology
This species is typically found within reed beds or in areas
of dense, tall grass with thick reed or cane-like stems,
typical of riverine and other similar habitats.
At more than 4.5 kg, Greater Cane Rats are the second
largest rodents in Africa. They feed on roots, reeds and
the stems of grasses along rivers and in other moist areas.
Grasses eaten include Couch Grass (Cynodon dactylon),
Swamp Grass (Hemarthria altissima), Elephant Grass
(Pennisetum purpureum) and Guinea Grass (Panicum
maximum). While grasses are their principal food, they raid
crops (such as maize, millet, sorghum, wheat, and sugar
cane) and cause damage by cutting the stems at their
base with their broad sharp incisors (Skinner & Chimimba
2005).
Greater Cane Rats are predominantly nocturnal or
crepuscular. They are polygamous, with a single male
observed with a number of females and their offspring.
Although they are generally reported to be solitary, family
groups of up to ten may live in restricted areas (Skinner &
Chimimba 2005). Two litters of as many as 12 young are
born annually (Skinner & Chimimba 2005), with two to four
pups per litter the norm in all southern African countries
for which data are available (van der Merwe 1999).
