Abstract
The study aims to test the effects of Senna siamea (Lam.) Irwin & Barneby leaf extract on the feeding behavior of house sparrows (Passer montanus), with the goal of applying it as a bird repellent. The experiment involved drying Senna siamea leaves and grinding them into a fine powder using a blender. The powdered leaves were then extracted using soxhlet extraction with 70% (v/v) ethanol as the solvent. Birdseed was soaked in the extract for 24 hours at three different concentrations: 2%, 5%, and 10% (w/v), while the control group consisted of untreated birdseed. A total of 12 house sparrows were used in the experiment, with three birds per treatment. Each bird was placed in an individual cage. For the feeding test, 20 grams of food was provided to each bird, and they were allowed to feed freely for 24 hours. After the feeding period, the remaining food weight and the weight of bird feces were recorded. Data were analyzed using one-way analysis of variance (ANOVA) to determine the differences between the treatment groups. The results showed that the mean food intake among the groups differed significantly (p<0.05). Similarly, the mean weight of bird feces showed a significant difference (p<0.05) compared to the control group. However, there was no significant difference in feces weight among the different treatment groups. These findings suggest that Senna siamea leaf extract at the tested concentrations effectively inhibits the feeding behavior of house sparrows. However, the birds' excretion behavior remained normal and proportional to the amount of food consumed.
