| dc.description.abstract | The present study documents activities and diet of African jacana (Actophilornis africanus) in Lake Hawassa. Data were collected during the wet (July- August) and dry (January- February) seasons in 2017 using scan and focal sampling methods. Repeated observations were administered to collect data on activity pattern and foraging behaviour of African jacanas. Activity patterns including feeding, scanning, flying, preening, resting and others were observed. African jacana feed primarily on insects (63.7%). They also feed on worms (16.2), larvae (5.4), snails (5%), seed (3.7%) and other (6%) during the wet season and during the dry season insects (55.6%), worms (12.2 %), larvae (8.2%), snails (7.1%) seed (6.5%) and other (10.3%) There was significance difference in the type of food consumed by African jacana during the wet season (F1 39 = 7.86, P< 0.05) and during the dry season (F1 39 = 3.11, P< 0.05). There was no significance difference in the type of food consumed between seasons (F1 39 =1.48, P> 0.05). Major activities of the species were mainly feeding 95.8 ± 5.6 and 149.3 ± 8.9 during the wet and dry seasons respectively. Feeding activity was intensive and reached its peak in the morning (6:00 - 9:00) and late afternoon hours (4:00 – 6:00). Resting was more during the mid-day (12:00 – 1:00). During the dry season, there was significant difference in the rates of feeding (F0.05, 118 = 15.24, P < 0.05) in the three time periods. The mean feeding rates were significantly higher in the morning than late afternoon (Post hoc Tukey HSD, p < 0.05). There were significant differences in the mean rates for scanning (F0.05, 118= 6.9, p < 0.05), flying (F0.05, 118= 5.03, p< 0.05), resting (F0.05, 118=4.33, p < 0.05) during the different periods. Further ecological studies on African jacana should be conducted to get more information about the bird and facilitate conservation measures in the study area. | en_US |
