and their study also revealed that diet varied from year to year during May, September and October, and was most diverse during August. In Front Range of Banff national park, food habits were studied by Hamer and Herrero (1987b) during 1976-1980 and their study revealed that horsetails (E. arvense) were the main food of grizzly bears during summer. Graminoids (grasses, sedges and rushes) were another major food component of the grizzly bears from May through September. Their study also indicated that ants (Formicidae) occurred frequently in the bears’ diet. All species of bears, except polar bears (Ursus maritimus), feed on insects, especially ants. In this chapter, we envisaged to study food habits of brown bear in Kugti wildlife sanctuary. 4.2 Methods The food habits of Himalayan brown bear were determined by analyzing scat samples and direct observations on feeding activities and signs. Brown bears were seen actively feeding during the day time. Diet composition and seasonal variation were studied during the years 2002-2004. 4.2.1 Collection of scats From April 2002 to December 2004, scats were collected from different parts of Kugti wildlife sanctuary, though systematic collection technique was not feasible in the mountainous and often rugged terrain. Scats were mainly collected while walking on the 22 transects. Scats were also collected from areas other than transects. Photograph 7, 8 and 11 show collections of bear scat in Kugti wildlife sanctuary. All 50
these scats were separately placed in plastic bags and properly labeled date-wise and area-wise. Samples were air-dried in the field and stored. 4.2.2 Analysis Firstly, we calculated the minimum number of scats required for the analysis as shown in figure 1 which could provide significant results. On the basis of number of food items and scats, items/species area curve was plotted to find the minimum number of scats required. Out of the total collection, 222 scats were analyzed; 72, 69 and 81 scats were taken from the summer, monsoon and fall season respectively. Scats were analyzed both qualitatively and quantitatively. At the time of analysis, scats were weighed separately and only 10% of each scat was taken for the purpose of analysis. Portion of scat sample was immersed in water in a beaker for 10-15 hours. Following this, scats samples were rinsed thoroughly using sieves to remove fruit, vegetative and undigested material, and then suspended in water. Scat samples were also washed in running water to remove the mud and other mix matter using 0.4mm and 0.7mm sieves. Remaining portions of scats were kept in Petridish for oven drying for 15-24 hours at 60º C. Then the scat samples were analyzed manually by separating different components viz. hairs, bones, claws, teeth, fruits, seeds, ants, insect parts and plant matter. Most plants were identified to species level using reference slides and food plants were recorded in the field area. Scat contents were easily identifiable when collected fresh in the field, and the plant remains were easily comparable with reference plant specimens (slides). After the course analysis in the field, scat materials were brought to the laboratory for further 51
