NIKHIL KHANNA - Sundar Nagar is a residential colony. It has 148 houses built on 950 square yard lots. Sundar Nagar New Delhi Delhi

Despite Sundar Nagar being a leafy, tree-filled area which adjoins the huge Delhi Zoological Park, sparrows have completely dissappeared from here. This is surprising and disturbing as the plot sizes and the sizes of the houses remain the same over the last 50 years. In addition, the gardens in front of all the houses remain the same. In fact, these gardens are visited by parrots, pigeons, doves, magpies, and numerous other birds. Sundar Nagar, touchwood, is full of birdsong, huge numbers of eagles circle the skies above it-but the sparrows who were ubiqitous once, have completely dissappeared. Other birds are still nesting in the many trees in Sundar Nagar as are they in bouganvillea bushes.There is no sign of the sparrows. If indeed instectisides were affecting them, then would'nt those very insectisides affect the other birds? And since other species of birds still forage the gardens in front of homes for insects, how come the sparrows are not there? Same goes for telephone towers-should'nt these be affecting other species as well?
