Alpine Shrew

Identification

The Alpine shrew is a tiny mammal, measuring just 6 to 7.7 centimetres in body length with a tail as long as its body, and weighing a mere 5.5 to 11.5 grams. Despite its diminutive size, it has several distinctive features that help identify it in the field. It displays uniform greyish-black colouring on its upper surface, with greyish-brown underparts, and its most striking features include a long pointed snout, small black eyes, and distinctive rounded pink ears. The legs and feet are white, and the underside of its hairy tail is yellowish. The tips of its teeth are characteristically reddish-brown. Juveniles are noticeably paler than adults, which can aid in age determination. In areas where it shares its range with the common shrew and the Eurasian pygmy shrew, the Alpine shrew is readily distinguishable by its darker fur and proportionally longer tail.

Range & Habitat

The Alpine shrew inhabits the mountains and uplands of Central and Eastern Europe and parts of France, with its range encompassing the Alps, the Black Forest, the Jura Mountains, the mountains of southern Germany, the Giant Mountains, the Beskids, the Tatra Mountains, the Carpathian Mountains, the Transylvanian Alps, the Vosges uplands, and the mountains of the former Yugoslavia. The species occurs at elevations between approximately 200 and 2,500 metres. Although occasionally found above the tree line, it characteristically favours damp pastures and swampy ground near small streams, particularly in areas with dwarf sparse conifers near the upper limit of tree cover.

This shrew shows a strong preference for dense vegetation and rocky terrain, often occupying rock crevices and living under boulders or fallen branches. It frequently occurs near mountain huts, suggesting some tolerance of human proximity. Notably, the Alpine shrew was recorded in the Spanish Pyrenees in the early 20th century but is now presumed locally extinct there due to the absence of modern sightings.

Behaviour & Diet

The Alpine shrew is nocturnal and a skilled climber, using its distinctive long tail for balance as it navigates through alpine vegetation and rocky terrain. Like other shrews, it possesses scent glands on its flanks which it uses to mark its territory. With the high metabolic rate characteristic of shrews, it must feed frequently throughout its active periods.

The Alpine shrew's diet consists of insects, spiders, snails, and earthworms, making it an important predator of small invertebrates in alpine ecosystems. However, its small size makes it vulnerable to predation, and it falls prey to foxes, weasels, domestic cats, and tawny owls.

Best Time & Places to See It

Finding the Alpine shrew is challenging due to its nocturnal habits and preference for dense vegetation and rocky refuges. Your best opportunities lie in the major mountain ranges where it is known to occur: the Alps, Carpathians, Tatras, and other Central European uplands. Focus your search in damp alpine meadows and coniferous forest zones between 200 and 2,500 metres elevation, particularly near small streams and swampy ground. Areas with dwarf sparse conifers near the tree line are especially promising. Searching near mountain huts may also increase your chances, as the species is known to frequent such areas.

Photography Tips

Photographing the Alpine shrew presents considerable challenges given its nocturnal nature, tiny size, and preference for concealment. Night-time searches using red-light torches or infrared equipment may reveal the species moving through dense vegetation or near streams. A macro lens is essential to capture detail of this diminutive creature. Given its rarity and conservation status as "Near Threatened," it is important to prioritise the animal's welfare over photography opportunities, avoiding excessive disturbance or handling. Patient observation and stillness near suitable habitat during twilight hours may occasionally reward the dedicated naturalist with a glimpse of this elusive alpine resident.
