House sparrows had made nest in our varanda and we had shown our children hatching of the chicks.
Now we do not see this bird any more. The situation is so not only in India but almost the world over. The name suggests that the bird lived in association with man because of protection from the carnivores. The urban areas (like our kitchen garden, park, lawns) we do not use pesticides and herbicides; there has been no change in the architectural designs of the buildings in the city. There, however, is one change since that period, i.e. the emergence of cell-phone towers - more in urban areas. The emergence of cell-telephony and decline of house sparrows (birds being very sensitive) coincides. The phenomenon is worldwide and more in the urban areas. This is a logic which is by and large acceptable to many Ornithologists, especially who are not stuck to the old concept of use of pesticides which are not the same everywhere. The pesticides had been in use since long.
I have been working on this aspect with scientific approach. Although not on sparrow eggs (that I can't get in good numbers for my experiments that too repeatedly), but on fertilized hen eggs. The results of the effects of cell-phone radiations on chick embryos are clear. I will share the results after completing the studies.
