The Philippine Spotted Deer — also called the Visayan Spotted Deer (Rusa alfredi) or Alfred’s Deer — is an endangered species endemic to the Philippine Islands. It lives on the Visayan island chain. This deer was recognized as its own species in 1983.
On this page you’ll learn facts about the Philippine Spotted Deer including its size, what it looks like, reproductive cycle, habits and behavior and its native habitat.
How Big is the Philippine Spotted Deer?
- Head & Body Length – 120 to 130 cm
- Shoulder Height – 60 to 80 cm
- Tail Length – 8 to 13 cm
- Weight – 40 to 60 kg
What Does the Visayan Spotted Deer Look Like?
This species of deer is a small, short-legged deer. It is similar in appearance to the Sambar species of deer.
The most distinctive feature in this species are the many large rounded spots scattered over the dark brown flanks.
The under parts are paler in color. There is a white patch of fur on the chin, and the insides of the ears are also white.
The eyes of the Philippine Spotted Deer have pale colored hairs around them in a ring.
The tail is short with a white underside.
Males have short, but distinctive antlers of about 20 cm in length; these have a short brow tine.
Where Does This Deer Live?
Now let’s take a closer look at its historical and present-day range and the preferred habitat of the Philippine Spotted Deer.
Distribution & Range
Historically, you could find the Visayan Spotted Deer on a large number of islands of the Visayan chain in the central Philippines.
However, due to over-hunting it has become extinct on a number of these islands and today it can only be found on 4 of the larger islands in the Visayan chain.
It remains under threat from over hunting.
Preferred Habitat
The preferred habitat of the Philippine Spotted Deer is clearings and glades in thick, lowland tropical forest.
However, this habitat has disappeared as it was clear-cut for agricultural purposes.
Today, you can find Alfred’s Deer on thickly forested mountain slopes that are too steep to cultivate.
Mating Habits & Reproductive Cycle
The rut occurs late in the year between November and December. Males have a distinctive rutting call that is part of this deer’s mating ritual.
The young are born after an eight month gestation period in May or June.
At 6 months of age, fawns are weaned. This deer reaches maturity at 12 months.
Interesting Behavior
We don’t know much about this animal’s way of life. It has not been thoroughly studied.
This species of deer is nocturnal. Alfred’s Deer emerge at dusk to feed.
The Philippine Spotted Deer seems to be mostly solitary in its habits. They feed on a variety of different types of grasses, and have a maximum lifespan of about 15 years.
Someone will need to take conservation action to ensure this species is not hunted to extinction in the near future.
What Do Philippine Spotted Deer Eat?
The Philippine spotted deer is primarily a grazer and low browser. Young grasses growing in forest clearings appear to make up the bulk of its diet, supplemented by tender leaves, buds, and low-growing herbs it can reach without straining. Like many forest deer, it is drawn to regenerating vegetation, and animals have been reported feeding in recently cleared or burned patches where fresh green growth is abundant. Because the species has never been studied intensively in the wild, the finer details of its menu remain poorly documented. For a general picture of how deer diets work, see our guide to what deer eat.
How Endangered Is the Philippine Spotted Deer?
This is widely regarded as one of the rarest and most threatened deer in the world. The IUCN Red List currently classifies the Philippine spotted deer as Endangered, and the trend behind that listing is sobering: the species has vanished from most of the islands it once occupied, and today the surviving wild populations are generally considered to be confined to Negros and Panay, with only fragments of suitable forest left even there.
Two pressures drive the decline, and they reinforce each other:
- Deforestation — the Visayan islands have lost the great majority of their original lowland forest to logging and agriculture, leaving the deer squeezed into steep, isolated mountain patches
- Hunting — despite legal protection, poaching for meat continues in and around the remaining forest blocks
No one knows exactly how many Philippine spotted deer survive in the wild. Surveys are difficult in the rugged terrain the species now occupies, and published estimates vary; what is consistently agreed is that the total population is small, fragmented, and still under pressure. You can read more about how such assessments are made in our overview of deer conservation.
Captive Breeding: A Safety Net for the Species
One piece of good news is that the Philippine spotted deer breeds readily in captivity. Conservation breeding centers in the Philippines, together with a coordinated program among European zoos, maintain a captive population that serves as insurance against extinction in the wild. These programs also keep careful pedigree records so that the captive herd stays genetically healthy, and they raise the possibility of future reintroductions if enough forest can be secured and protected.
Philippine Spotted Deer vs. Philippine Brown Deer
The Philippines is home to more than one endemic deer, and the two are easy to confuse on paper. The Philippine brown deer is taller, longer-legged, and plain dark brown as an adult, and it survives on many more islands. The Philippine spotted deer is smaller and stockier, and — unusually among deer — it keeps its pale spots throughout adult life rather than losing them after fawnhood. In most deer species, spots are camouflage worn only by the young; in this species the dappled pattern persists on the dark coat of full-grown animals, which is what gives the deer its name. Both species belong to the genus Rusa, making the widespread rusa deer of Indonesia another close cousin.
Why does the Philippine spotted deer keep its spots as an adult?
The honest answer is that biologists are not entirely sure. Retained adult spotting is rare in deer, and in this species it may simply help break up the animal’s outline in the dappled light of dense tropical forest. Whatever the reason, the pattern makes adults look strikingly different from most other members of the deer family.
How many Philippine spotted deer are left in the wild?
There is no precise, agreed count. The remaining wild animals live in remote, steep forest on Negros and Panay where surveys are hard to carry out. Published figures are best treated as rough estimates, but all of them point to a small population measured in the hundreds to low thousands rather than tens of thousands.
Where can you see a Philippine spotted deer?
Seeing one in the wild is extremely unlikely — the species is nocturnal, shy, and confined to rugged forest. Your realistic options are conservation breeding centers in the Philippines and a number of zoos, particularly in Europe, that participate in the species’ managed breeding program.
