Northern Luzon Slender-tailed Cloud Rat

Lower Risk/Near Threatened
Description: Pelage is variable but typically predominantly white with a distinct black mask and collar. Pure white specimens are also known. Upon birth, its color is white and as it grows older, its coloration changes. They are distinguished from other murid rodents by their large size and densely furred tail. Adults head and body length is 12"-20", tail length is 8"-14", and weight is about 31/2 - 5 pounds. (Males 2.5-3.0 kg; females 2.0-2.5 kg).
NORTHERN LUZON SLENDER-TAILED CLOUD RAT CONTINUED
Range and habitat: Northern and Central Luzon, Philippines; discontinuously distributed through 12 provinces of Luzon north of Laguna; highly adaptable occurring in a wide variety of habitats from sea level to at least 2000m high mountains.
Habits And Adaptations: Ecology and behavior of the cloud rat remains poorly known. Cloud rats are nocturnal and arboreal. They have large hind feet that are highly specialized for arboreal life and large foreclaws. They live alone, in pairs or in pairs with one or two dependent young. Phloeomys are highly adaptable and able to persist in some seriously degraded habitats including agricultural and pasture land as long as sufficient cover remains unlike the closely related Crateromys species of cloud rat.
Diet: In the wild, the cloud rat feeds on tender young leaves, fruits and roots. At the Zoo, the cloud rat eats rodent blocks, greens, yam, canned primate diet, nuts and as treats they get orange, apple, corn-on-the-cob, carnivore meat, and crickets. Cloud rats seize their food with their forepaws and eat while in an upright posture, chewing loudly.
Breeding And Maturation: Births occur in all months. Females have an interval of 8 months between births. Estimates of gestation period range from 65- 95 days. They give birth to a single young weighing 100-150g which the mother keeps firmly attached to a nipple when she is in the nest. The young are born in tree holes or hollows of standing or fallen trees or in holes in the ground. Young are weaned at 5 months of age. Sexual maturity was attained at 8 months in females and from 12- 18 months in males. Estrus cycles ranged from 10 -15 days. This species thrives in captivity and has been known to live 13 - 15 years.
Conservation Notes/Status: This species is endemic to the Philippines and specifically to Luzon. IUCN classifies P. palllidus as near threatened but they have a large range and are reported to be locally abundant. This species is economically important to the local tribesmen as an alternative source of protein and its hide is used in making bags, belts and hats for export trade thus it is intensively hunted.
Miscellaneous: Cloud rats are known for their fruity, musky odor as a defense mechanism to ward off other animals but it also is used as a tracking device for humans much to their demise. There are six known species of cloud rats and one is already considered extinct. Locally known as "dagang buut".

Interpretation:
Q. Are these really rats? They don't look at all like a rat should look.
A. Yes, they are grouped in the Muridae family which includes rats and mice. The word "rat" often brings to mind a squinty-eyed, voracious animal that breeds prolifically unless constantly opposed through trapping and poisoning. But most rat and mouse species are well-mannered, clean, rather pretty and shy and pose no threat to humans. Of the 63 species of rats and mice in the Philippines only 6 are responsible for causing more than minor damage to anything and those six were all accidentally imported from the Asian mainland. Each of the native species is an important part of the biological community.
Q. Why do we only have one animal?
A. The Minnesota Zoo is only the second zoo in the country to exhibit this species of cloud rat. The Bronx zoo in New York has only about 10 individuals and is very particular about who receives any surplus animals. The male we received was from their most recent litter and was born in March 2001. We hope to receive a female from Bronx when one becomes available. The Philippine government is very restrictive on any importations of their native fauna and it would be very difficult to receive any animals directly from their native country.

Slender-tailed cloud rats are quiet, timid animals that weigh up to two and a half kilograms and feed on tender young leaves in the rain forest.
Rats and mice have a bad reputation. The very word "rat" in English immediately brings to mind a squinty-eyed, ugly, voracious, disease-ridden, aggressive animal that breeds prolifically unless constantly opposed through trapping and poisoning. There are, of course, such animals, and we all know them only too well. But most rat and mouse species are well-mannered, clean, rather pretty, and shy, and they pose no threat to humans. Of the 63 species of rats and mice in the Philippines, only six cause more than very minor damage to anything, and those six were all accidentily imported from the Asian mainland, and are not native to the Philippines. Each of the native species is an important of the food-web that binds together the rain-forest biological community. They range from such small and surprising species as the Isarog shrew-rat (mentioned at the beginning of this book) to such large and startling species are the slender-tailed cloud rats.
Weighing up to two and a half kilograms, the slender-tailed cloud rats (Phloeomys pallidus) are the largest "rats" in the world, using the taxonomic rather than the popular definition of a rat. But few people would recognize them as rats; most Americans and Filipinos would guess from their long, furry tails, large eyes, and quiet disposition that they are strange squirrels. The color pattern of one of the two known species of this rat, though, is different from any squirrel's: The species from central and northern Luzon is mostly covered in nearly white fur with dark ears, dark tail, and a dark brown mask around the eyes, nose, and mouth. Some populations have a brown cape over the shoulders. The species from southern Luzon (Phloeomys cumingi) is a deep mahogany brown all over; a group of related species, the bushy-tailed cloud rats, (the genus Crateromys), includes one species with long, flowing, coal-black hair covering the entire body, and another that is bright orange over most of the body, but with a tail that is pure white for the last half of its length.
As far as we know, all of the cloud rats feed on tender young leaves in trees that grow in lowland rain forest. They are slow-moving and seem to spend a great deal of time digesting their latest meal. In a large hollow tree or log, the females give birth to one young per year, which stays with the mother (the father hangs around only for mating) until the next young is born a year later. At one time, they probably were the primary prey for bird and mammal carnivores over much of the Philippines, possibly including the Philippine eagle in the Sierra Madre Mountains, where both the eagle and cloud rat were common until the end of World War II.
Because they are large and meaty, the cloud rats are all heavily hunted; one subsistence farmer living at the base of Mount Isarog told us that he used his dogs to track and kill 50 per year. The combination of heavy hunting and habitat destruction has led to one species probably having gone extinct (on Mindoro), one that is critically endangered (on Panay), and the four others being threatened to varying degrees. Ironically, the cloud rats appear to be the only native species of "rats and mice" in the Philippines that have any economic impact, either positive or negitive. If the habitat were protected and hunting effectively regulated, they could remain a source of protein to poor farmers. Extinct species, however, are notoriously poor at providing any benefits.
