Black rat (Rattus rattus)
Large rodent, with a long body, tail and ears, and a pointed snout. The dorsal coloration is rather dark, while the ventral one is lighter (between white, yellow and grey). Thanks to its commensalism, it can be distributed throughout the territory, from very low levels near the sea, to... Read more →
Brown rat (Rattus norvegicus)
Large rodent that is easily differentiated from its relative, the black rat, by its coloration and by having a more rounded snout and a tail that does not exceed the length of the head-body. It presents grey coloration on the back that delimits with a lighter or yellowish tone on the... Read more →
House mouse (Mus musculus)
Small rodent, slightly larger than the Algerian mouse, from which it differs by having larger ears and a longer tail in relation to the body. There are two main colours, one rather dark (greyish) that generally corresponds to commensal populations (that live in humanized environments),... Read more →
Algerian mouse (Mus spretus) Moderate decrease
Small rodent, with a rounded snout and short ears, and a tail that does not exceed the length of the body. It has light brown dorsal coloration and light ventral coloration (similar to the field mouse). Their diet is vegetarian, and is supplemented with small invertebrates. It is a... Read more →
Yellow-necked mouse (Apodemus flavicollis) Stable
It is a small rodent with brown dorsal coloration (with reddish/golden hues) that contrasts strongly with the white ventral coloration in adult individuals. Their external appearance is very similar to that of the field mouse, as are their diet and... Read more →
Wood mouse (Apodemus sylvaticus) Moderate decrease
It is a small rodent with brown dorsal and ventral white-gray coloration. It has a very varied diet, mainly based on seeds and some food of animal origin (invertebrates). It is the most abundant small mammal in forest environments and is a key taxon for its role in the diet of many... Read more →
Water vole (Arvicola sapidus)
It is a rodent of the family of arvicolids of medium size and with adaptations to semi-aquatic life. Their fur is dense, short, and brown, and partially covers the ears. The belly is ash color with yellowish tones. It has a very specialized diet in stems and leaves of herbaceous plants... Read more →
