BEHAVIOUR OF JUVENILE ASIAN ELEPHANTS IN Panicum maximum DOMINA TED GRASSLANDS IN THE UDA WALA WA NATIONAL PARK.

Abstract

Guinea grass (Panicum maximum) dominated grasslands, a major habitat typein the Udawalawa National Park, is frequently occupied by wild elephants.Behaviour of juvenile elephants (4-6 years old) inhabiting the habitat wasstudied from April 2004 to March 2005. Focal animal sampling was employedto quantify behaviour and total time of observation was 3100 minutes.

The activity budget of the juveniles comprised of ten behaviour patterns;feeding (44%), resting (24%), locomotion (19%), play (5%), comfort (5%),drinking, social, exploratory, agonistic and anxious. Maximum feeding (55%)and minimum resting (13%) were recorded during late afternoons (1500-1800hrs) whilst maximum resting (37%) and minimum feeding (29%) wererecorded during late mornings (0900-1200 hrs). Locomotion and otherbehaviour patterns did not significantly vary with time. Time spent on feedingwas higher in wet months (47%) than in dry months (39%). Resting wasrelatively higher in dry period (27%) than in wet (21 %). P. maximum was themajor food type consumed throughout the year while they fed on native grassesand herbs to a lesser extent (21-29%). Significant correlations between ambienttemperature and time spent on feeding (r= -0.716) and resting (r = +0.751)were evident.
