|Abstract: ||This study determined the avian fruit utilizers of the plants Carissa edulis and Jasminium dichotomum both
related in the colour and size of their fruits. Furthermore, the study also compared the two plant species in terms
of the diversity of avian fruit utilizers, their frequency and duration of visits and activities performed during
visits to the plant species. Data was collected in the Amurum Forest Reserve, north central Nigeria, between
June and July 2011 through focal observations. A total of 107 individual birds comprising 22 species were
recorded during the study. C. edulis had the highest diversity and abundance of bird species as compared to J.
dichotomum. Seven bird species were exclusively found on C. edulis while 5 bird species were exclusive to J.
dichotomum. The Common bulbul (Pycnonotus barbatus) and Speckled mousebird (Colius stratus) were the
most common bird species observed on the two plants. Mean time spent foraging differed significantly across
bird species foraging on C. edulis but not on J. dichotomum with the Western grey plantain-eater (Crinifer
piscator) spending the highest time foraging on the former. Activities performed by bird species on the two
study plants include foraging and perching which did not differ significantly between plants. These observations
highlights the ecological importance of the two plants within the reserve particularly in enhancing the survival of
other animal groups within the reserve.|
