| dc.description.abstract | An activity budget provides a quantitative description of how animals spend their time engaging in various activities such as foraging, maintenance and reproduction that directly relates to an animal's metabolism, making it a crucial aspect of studying behavioural ecology. Lesser adjutant Stork ((Leptoptilos javanicus) is a globally vulnerable species with declining population and increasing threats. Hence, its activity budget and foraging behaviour was studied for two seasons [monsoon (August 2022) and winter season (January 2023)] in Chitwan and Rupandehi-Kapilvastu area to find the seasonal behavioural activities and factors affecting its feeding success. Extensive road survey method was used to collect the LAS behavioural video footage and activity budget was prepared. Lesser Adjutant Stork spent maximum time foraging (mean 9.97 ± 8.25 min) followed by resting, vigilance, maintenance, other and locomotion activity. There was a variation in the time spent by LAS on foraging and resting in between two seasons [foraging behaviour (t-value = 8.203, df = 237, p <0.05) and resting behaviour (t = 8.341, df = 140, p<0.05)]. Time spent for foraging was higher in monsoon (1565.56 min, 78% of total time duration) while time spent on resting (751.03 min, 27% of total duration) was higher in winter season. LAS used visual mode (96%) of foraging rather than tactile (4%). The snails (n = 477) was major prey species followed by insects (n = 73), crabs (n = 19), fish (n = 15), frog (n = 8), snake (n = 9), lizard (n = 3), carcasses (n = 2) and mouse (n = 1). Distance to road (Estimate = -0.0022 ± 0.0009, p = 0.0171) and the distance to wetland (Estimate = 0.0013 ± 0.0006, p = 0.0426) are influencing factors for feeding success on LAS. | en_US |
