This little Striped Grass Mouse (Rhabdomys pumilio) or Four-striped Grass Mouse was quite unperturbed at my presence this afternoon as he shared some corn with all the other garden birds. I often see a pair together snacking on seeds I put out.

As its common name suggests, the four-striped grass mouse is easily identified by the 4 distinct dark longitudinal stripes running the length of the back. Colour varies from dark grizzled russet brown to a grey-white. The sides and underparts are lighter but vary from off-white to pale grey-brown. The backs of the ears and the snout are russet to yellowish brown. The upper surfaces of the feet are usually lighter in colour than the body. Research has shown that the average body size does vary in different geographical areas, and that tails can be shorter or equal to the body length.

Length 19-26cm, weight about 43g. Diurnal and occuring in all parts of South Africa except most of Limpopo. Prefers fairly dense cover and feeds mostly on green vegetable matter, seeds and insects. Also likes the soft parts of the bracts and flowers of Proteas thus becoming an important agent in the pollination of some species. They excavate burrows, sometimes to a depth of 50cm. Striped mouse are active during the day, but are seldom active at night as they cannot maintain their body temperature if the environment is below 5 degrees C.

Afrikaans : Streepmuis
Die Streepmuis (Rhabdomys pumilio) is ’n muis wat in die hele Suid-Afrika voorkom behalwe in die grootste gedeelte van Limpopo en die noorde KwaZulu-Natal. Die streepmuis is bleek rooibruin in die weste tot donker grysbruin in die ooste van die area waarin hy voorkom. ’n Kenmerk van die soogdiertjie is die vier strepe op die rug. Die streepmuis is daglewend en word tot 19cm lank en weeg 30 – 55g. Hierdieie knaagdiertjie woon in grasryke dele in halfwoestyn tot bergwêreld met hoë reënval en is daglewend. Die streepmuis grawe gate onder ou gras of by die basis van ’n bos met voetpaadjies na die weigebied. Hulle eet sade en ander plantmateriaal. Daar word gewoonlik 5-6 kleintjies in die somer gebore.

Striped Grass Mouse

Rhabdomys pumilio : Common name - Four-striped grass mouse. Streepmuis in Afrikaans

A Striped Field mouse in my garden. He's quite tame as I often put out seeds for them, and here I was within a meter from him. He was actually very disgusted, drying himself off as I had accidentally gotten him wet while watering the garden with the hosepipe.

 

I tolerate these lovely little creatures (unlike rats!) as they are totally harmless and very rarely venture into the house. I've only ever seen this pair in my garden and was actually hoping to see little ones scurrying about!

Rhabdomys is a largely Southern African genus of muroid rodents slightly larger than house mice. 

 

Here they are snacking on some sunflower seeds I put out for them in my garden. 

The Striped Mouse, so named because of the four longitudinal black stripes down its back, is an opportunistic omnivore, and has a varied diet. In certain areas they are mainly granivorous, while in others they may eat more plant material than seeds. They also enjoy a wide variety of other vegetable matter and insects.

The striped mouse helps to pollinate many Protea species, as pollen clings to its head while it is feeding. When the mouse moves off to feed on other neighboring flowers of the same species, it carries the pollen with it, thus assisting in the fertilization of these flowers. They normally excavate a burrow at the base of a grass thicket, ensuring that the entrance is well hidden, and lining the chambers of their burrows with soft, leafy debris; alternatively, they construct a ground-level nest under cover of dense stands of tall grass.

 

Striped Mouse forage by day, particularly in the early morning and late afternoon, and are often seen among the tall grasses growing on the perimeter of cultivated land. In central Africa, where striped mice are also found, they breed throughout the year, but in the south the breeding season is usually confined to the summer months (September to May).

During the breeding season the adult females appear to be territorial, with limited home ranges which probably overlap the large home ranges of the males. There are from 2 - 9 young per litter.
