Philippine long-tailed macaque height of 40–50 cm (16–20 in). It is the size of a domestic cat. Male macaques weigh 4–8 kg, but females only attain 3–4 kg. The Philippine long-tailed macaque is found in all major Philippine island groups (Luzon, Visayas, Mindanao). However, though assessed Near Threatened, it is actually in serious retreat or already extinct in much of its original range.

While females are active in choosing sexual associations, the mating behaviour of macaque social groups is not entirely determined
