Campbell's dwarf hamster

Campbell's dwarf hamster (Phodopus campbelli) is a type of hamster named for Charles William Campbell. He found the first one in Mongolia in 1902. This small hamster looks much like the Winter white dwarf hamster. One way to tell them apart is that Campbell's dwarf hamster often has a narrow dorsal stripe and brown or gray fur on its belly.

People can keep these hamsters as pets in captivity. They are easy to care for and like to explore.

In the wild, Campbell's dwarf hamsters live in burrows with many tunnels. They live in the steppes and semi deserts of central Asia. This includes places like the Altai Mountains, parts of Tuva, and the Hebei area in northeastern China. These hamsters are active at dawn and dusk. They eat plants and insects. They can have babies almost any time when kept as pets.

Campbell's dwarf hamster is considered Least Concern by the International Union for Conservation of Nature. This means the species is doing well in the wild. It is found in several countries, including China, Kazakhstan, Mongolia, and the Russian Federation. These little hamsters make interesting pets and help us learn about nature in Asia.

Taxonomy and naming

The binomial name of Campbell's dwarf hamster is Phodopus campbelli. It was named after C. W. Campbell, who first found it on July 1, 1902, in Inner Mongolia. Campbell's dwarf hamster is often confused with the Djungarian hamster (Phodopus sungorus) because they share some common names, such as the Siberian hamster.

American biologist Ned Hollister described a subspecies in 1912:

• P. c. crepidatus : Found in the Altai Mountains of Siberia

Description

Campbell's dwarf hamsters are small animals. They can be a little different in size depending on where they live. Those found in the wild in Mongolia are usually about 80 mm (3.1 in) long from head to body, with a very small tail of 5 mm (0.20 in). Pet hamsters often grow a bit larger because they have better food.

These hamsters have white fur on their lips and cheeks. Their faces can be grey or brown. They have a dark stripe along their back. They use special glands and their urine to mark their space and talk to others. Unlike other similar hamsters, Campbell's dwarf hamsters have smaller ears, no dark patch on the top of their head, and a thinner back stripe. They also have special cheek pouches that reach to their rear legs, which they use to carry food.

Diet

Campbell's dwarf hamsters eat many different foods. Their food should have about 16-24% protein, 60-65% carbohydrates, and 5–7% fat. They also need fresh water every day. In the wild, they eat plants. In cages, they can eat special hamster food made from grains, nuts, and seeds.

They can also eat fresh vegetables like kale and fruits, and small amounts of protein-rich foods like mealworms or earthworms. It is good to give them things to chew on, like smooth wood from apple or willow, to keep their teeth healthy. Some human foods, like chocolate, can harm hamsters and should never be given to them.

Breeding

Campbell's dwarf hamsters in Tuva start their breeding season in April, while in Mongolia it begins in late April or early May. In the wild, breeding ends in late September or early October, but in captivity, they breed throughout the year, especially in the summer. Wild hamsters usually have three to four litters a year with about eight babies each. Females become ready to mate at two months old.

The pregnancy lasts between 18 and 20 days. When born, the babies are hairless and weigh about 1.5 grams, with their eyes and ears closed. Their fur starts growing after a few days, and they develop quickly.

Hybrids

Campbell's dwarf hamsters can breed with another type called P. sungorus in captivity, creating hybrid hamsters. While these hybrids can make pets, breeding them can cause health issues due to inherited problems. This can threaten the pure species. The hybrid offspring often have reduced fertility.

Distribution and habitat

Campbell's dwarf hamsters live in burrows in the steppes and semideserts of central Asia, the Altai Mountains, autonomous areas of Tuva, and the Hebei province in northeastern China. Their burrows have several tunnels and can be deep. Sometimes, they share these burrows with other small animals, like Daurian pikas, to avoid digging new ones.

These hamsters can also be found close to human homes, such as inside yurts in Mongolia, where they stay warm during winter. They have several predators, including owls and foxes.

Status and conservation

This hamster is listed as of Least Concern by the International Union for Conservation of Nature. It has many hamsters and no big dangers. But some homes might be at risk from more livestock in places like the steppes of central Asia. In dry places, there may be less water, which could be a small worry. These hamsters are protected in some places.
