Abstract
Background: The House Sparrow (Passer domesticus L.), is a human-commensal bird species, belonging to the order Passeriformes. The rapid changes in our lifestyle resulted in the decrease of this bird population during the past four decades. Among the various causes viz., lack of food resources, pollution pressure, indiscriminate usage of pesticides etc. Habitat loss is found to be one of the main threats for their rapid decline. Installation of artificial nest boxes was found to be the best alternatives for raising the bird population. Methods: Jangareddigudem of West Godavari district, Andhra Pradesh, India, was chosen as the study area. The nest boxes were designed by incorporating certain modifications to the basic model specified by British Trust of Ornithology. Installation of the nest boxes was initiated from an area with moderate food resources, located towards south-west edge of the town and was expanded in to other areas in a latitudinal wise towards north and south directions. Data was collected on a regular basis to study the occupancy of the nest boxes by the house sparrows. Result: The model designed was proved to be protective from predators and also well accepted by the public. Out of 570 nests that were installed in the study area, 550 nests were occupied and being used for breeding, that comes to around 97.6% occupancy indicating the suitability and protectiveness of this model. The sparrow population in the study area has been increased with a count of sparrows from few to 300+ sparrows at each roosting site (two roosting sites) by the end of 2020 by utilizing the nest boxes.
