The Cook mouse ( Mus cookii ) is a species of mice (genus Mus ) that lives in South and Southeast Asia from northeast India via Bhutan and Nepal to Bangladesh and northwest Myanmar as well as from central and eastern Myanmar and southern China occurs as far as Thailand , Laos and Vietnam .

features

The Cook mouse reaches a head-torso length of 7.7 to 9.6 centimeters with an approximately equally long, often slightly shorter, tail (8.3 to 9.1 centimeters) and a weight of 16.5 to 23 , 0 grams. The rear foot length is about 19 millimeters, the ear length 15 millimeters. The back fur is dark gray-brown and stiff and rough, the belly side is gray-white. The tail is clearly two-colored, dark brown on top and paler on the underside, the transition is not sharp. The Cook mouse resembles the rice field mouse ( Mus caroli ), but is slightly larger and the color transition of the tail is less sharply delineated, and the pale orange incisors of the upper jaw are missing.

The skull has a total length of 24 to 25 millimeters.

distribution

The Cook mouse occurs in two separate populations in South and Southeast Asia. The distribution area of the first population is in northeastern South Asia from northeast India via Bhutan and Nepal to Bangladesh and the northwest of Myanmar . The second population ranges from central and eastern Myanmar and southern China in the Yunnan province west of the Saluen to Thailand , Laos and Vietnam . In both regions the animals have an irregular distribution. The altitude distribution ranges from 50 to 2500 meters in the northwest and from 200 to 1500 meters in the southeastern population.

Way of life

The Cook mouse lives in different available and mostly disturbed or agriculturally used habitats , in China mainly in rice fields in the highlands. It also occurs in primary and secondary forests . In South Asia it is mainly found in subtropical, dry deciduous forests, in grasslands and in coniferous forests of more moderate climates. In Southeast Asia, on the other hand, it occurs only in wooded and slightly disturbed forest areas and gardens.

Systematics

The Cook mouse is classified as an independent species within the genus of mice ( Mus ), which consists of around 40 species. The first scientific description comes from Kathleen V. Ryley from 1914, who described the species using individuals from Burma, now Myanmar.

According to the analysis of morphological and molecular biological characteristics, the species is closely related to the rice field mouse ( Mus caroli ) and the falcon ( Mus cervicolor ).

Status, threat and protection

The Cook mouse is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN). This is justified by the very large distribution area and the frequent occurrence of the species, partly also in protected areas. There are no potential threats to the existence of this species.
