The Colombian rice rat (Handleyomys intectus) is a small rodent that lives only in Colombia. It's also sometimes called the white-footed Handley's mouse. This rat belongs to the Cricetidae family, which includes many types of mice and rats. It used to be grouped with other rats in the Oryzomys family. But in 2002, scientists realized it was very similar to another rat, the dusky montane rat. So, they both got their own new group called Handleyomys.
What It Looks Like
The Colombian rice rat is a medium-sized rodent. Adult rats are about 9 to 12 centimeters (about 3.5 to 4.7 inches) long from head to body. Their tail is usually about the same length as their body. These rats weigh between 17 and 34 grams (about 0.6 to 1.2 ounces).
Their fur is soft and brownish-grey over most of their body. This color slowly changes to a darker, grizzled grey on their belly. The tail has very little hair. It is dark on both the top and bottom, which is different from its closest relative. Also, unlike most other related species, female Colombian rice rats have only six teats, not eight. This rat also does not have a gall bladder.
Where It Lives
The Colombian rice rat is found only in the Central Mountain Range in northwestern Colombia. You can find them from the Antioquia Department in the north to the Valle del Cauca Department in the south.
They live in cloud forests. These are forests that are often covered in clouds or mist. They also live in nearby farm fields and pastures. These areas are typically cold but very humid. The rats live at elevations between 1,500 and 2,800 meters (about 4,900 to 9,200 feet) above sea level.
What It Does
The Colombian rice rat is a nocturnal animal. This means it is active mostly at night. It travels on the forest floor and does not usually climb trees. Scientists don't know much about its daily life. However, young rats have been seen during both the dry and rainy seasons. This suggests they might have babies year-round.
