Assessment of Population Density and Disparity of Village Weaverbirds (Ploceus cucullatus) Along Three Selected Road Axis in Ogun State, Nigeria

Abstract

Study of Village weaverbirds Ploceus cucullatus along the roads was necessary in order to provide prospect of their population, density and platform for monitoring their distribution. Data were collected through on-site observations and pointcount method at thirty-four (34) point-count stations. Collected data were subjected to descriptive statistics and one-way Analysis of Variance (ANOVA). 58.8% of the point-count stations were recorded along Abeokuta/Ibadan road axis, 26.5% along Abeokuta/Shagamu road axis and 14.7% along Ijebu-Ode/Ibadan road axis. Twelve different tree species representing ten families were found colonized by the bird but Cassia spp, Mangifera indica and Terminalia catappa were most preferred for habitation. Habitat use classifications indicated that Village weaverbirds predominantly nested in human settlements (94.2%). Total population of 1269 Village weaverbirds were recorded along the three road axis and highest population of it was from Abeokuta-Ibadan road axis. Overall, population density for the three road axis was 18 Village weaverbirds per kilometre and among the roads; Abeokuta-Ibadan road axis recorded the highest density. The total population mean Village weaverbirds was 223±13 Village weaverbirds while the total nest population was 129±nest. Total elevation value was 141±6 asl and the mean total of the tree species was 5±1 tree species. Maximum and minimum values of Village weaverbirds population, nest counts, elevation and tree species were recorded along Abeokuta/Ibadan road axis than other road axis. Elevation of point-count station was significantly different (P< 0.05). Elevation of the study locations contributed to Village weaverbirds population, density and population disparity along the road axis. ©JASEM
