FRUGIVOROUS BIRDS IN CONSERVING URBAN BIODIVERSITY

Sanjeet Kumar


Biodiversity is the components of all living & non-living things, which all are soundly associated to each other. Among the living, plants and birds are very much associated for their life sustainability and play a vital role to maintain the biodiversity. Urban deforestation is a serious problem due to much anthropogenic activities. A positive development in the developing city, in recent years has been the rapid increase in public awareness of the problems caused by deforestation. Birds play vital role in regeneration of fruiting plant species and help in the reforestation. The birds eat the fruits and help in the dispersion of seeds called frugivorous.  Frugivorous birds disperse the seeds of many plant species, forming mutualistic associations that render frugivores a priority for conservation in many habitats worldwide. There is richness of such birds in the urban area of Bhubaneswar. The most common observed frugivorous were Brown headed barbet, Chestnut tailed starling, Emerald dove, Golden oriole, Scaly breasted munia, Red-vented bulbul, Red-whiskered bulbul etc. along with vulnerable species like Pale capped pigeon



It was observed that the most common plant species are co-related to specific frugivorous such as, Trema orientalis with Pale capped pigeon, Tectona grandis with Oriental white eye, Artocarpus heterophyllus with Brown headed barbet, Diospyros ferrea with Black Drongo, Salacia chinensis with Ashy Drongo, Pennisetum pedicellatum with Scaly breasted munia etc. Also it was examined that Frugivorous birds showed similar regional abundance and richness, although fruit availability changed among seasons. However, the spatial distribution of frugivorous birds in the area should be changed with seasons. The present investigation strongly suggests making National Urban Forest policies to conserve the urban forest and the frugivorous vise versa. The conservation of this association will be very useful to give a sound biodiversity in an urban environment.
