Abstract: | Twelve langur infants (seven males and five females) of three focal bisexual unimale troops of Hanuman langurs,Presbytis entellus entellus living near Kailana, Jodhpur, Rajasthan (India) were observed for their weaning behaviour. Weaning starts between 7.0 to
10.0 months of age, average 8.6 months. The process of weaning lasts between 3.2 to 5.6 months, average 4.2 months. A 13-month-old
infant is fully weaned. Infants are independent at this age. Male infants are weaned earlier compared to females. Males react
to their mothers' rejections more fearlessly and are more vocal compared to females. By and large, infants were found in stress
during this period as their mothers are often very harsh, hostile, punitive, and indifferent to their infants. By severing
ties with their infants, mothers serve dual purpose of allowing their infants to become independent and may be to become ready
to bear offspring. |
