I am in search of "Effects of Technology" and it resulted in decline of sparrows.Two reasons for the decline in sparrow count are

1) They are eating the soft-bodied insects which eat pesticides.
2) They are effected with the Electromagnetic radiation from cell phone towers.

It reminds me of my childhood days when house sparrows were in abundance and making the nest at every possible place in the house.
