In Hong Kong Kam Shan Country Park, we noticed some white-furred macaques. Through morphological comparison with ordinary Macaque mulatta, we found that the white monkey' fur was much lighter, being white with light yellow fur tips. The white monkey skin, nails, limbs was also much lighter, the pupil color was slightly lighter, the sclera was red. So we tentatively determine these white monkeys are albino Macaca mulatta.
Observing the albino monkeys, we found they can get along well with other monkeys in the monkey troops by playing and grooming, which is very different from the description that albino monkey will be excluded by their troops.
Through morbidity statistics, we concluded that the rate of albino monkeys in Hong Kong is 1/116-1/600, which is much higher than the rate of albinism in wild animals mentioned in previous statistics (1/20000-1/1000000). We hypothesis that the reason of the abnormal rate is because the monkey carrying ordinary gene are sterilized, and monkeys carrying albino gene are no sterilized, in the contraceptive programme conducted by Hong Kong government.
