Soumya Banerjee - Milk Colony,Belgachia Kolkata West Bengal

I can hear them chirping as i write this. The locality clearly has a very large and healthy population of house sparrows that has remained stable over the past few years. However,the number of trees has gone down considerably,because the previously present green spaces have been taken over for building houses.The new housing complexes have no gardens/open spaces around them and very few sparrows are observed in such areas;the vast majority are seen in gardens/the few remaining green spaces. My house has a small attached garden where sparrows are frequently seen.
