Nesting characteristics of House Sparrow (Passer domesticus) in and around the Government Arts College campus, Udhagamandalm, The Nilgiris, Tamil Nadu.
- 1, ,
The present study was attempted to asses the House sparrows’ Passer domesticus nesting characteristics in and around the Government Arts College campus from December 2018 to March 2019 in Udhagamandalam, The Nilgiris.The result
shows that a total of 97 House sparrow nests were found on four nesting platforms namely Tiled houses, Buildings, Mud walls and Compound walls. Of which more number of nests were seen in Tiled houses (n=34). Overall nest height preference by house sparrow was minimum 0.5m and maximum 19.5m (6.85+0.48) and nesting platform height was minimum 8m and maximum 22m (10.84+0.55). There was a strong positive correlation observed between nest height and nest platform height (r2=90868 P< 0.00001). Overall the length (15.4+0.54) was higher than width (4.7+0.31) irrespective of nesting locations. The nests that were located on the Compound walls shows a negative weak correlation (r2=- 0.061859 P> 0.81609) between nest length and width. The direction of House sparrow nests shows that most of them were on North West Direction (n=29). The average distance between two nests was 19.4m irrespective of the nesting platforms. The nest entrance length (12.97+0.65) was always higher than the width (6.50+0.19) irrespective of nests with
positive strong correlation (r2=-0.29498 P< 0.0048). The present study suggests that preservation of thatched roof buildings, Mud walls and Concrete walls holes and ancient buildings are very much important in the city for supporting house sparrow populations. Modern urbanization and not in use of grains resulted to loss of habitat and food for house sparrow population.
