Population Structure, Home Range and Food Habits of Hanuman Langur in Gir Lion Sanctuary and National Park, India

Sharad Kumar, Jamal A Khan, Bharat J Pathak

Abstract


Aspects of ecology of Hanuman langur Presbytis entellus entellus were studied from January 2002 to March 2002.Langur troops were located through systematic surveys and by monitoring of road and foot transects. Visual countswere carried out and troops were classified into different age and sex categories. Data on food habits were collectedby direct observations. Adhoria and Pilipat troops were followed from dawn to dusk in order to determine the winterhome ranges of both troops. Troop size ranged from 45 to 15 individuals and average troop size was 19. Sex ratio,biased in favour of female, was 1% : 3.02&. Langurs utilised 41 plant species in the study area. The size of the winterhome range of Adhoria and Pilipat langur troop was 0.28 km2 and 0.44 km2, respectively. The findings of this studyare discussed in the light of result obtained in other studies carried out on Hanuman langur in India.
