i have read many article saying that decrease ans disappearance in no. of sparrows from many urban cities are due to the waves spread cell phone towers. do you believe this? according to me decrease in no. of sparrows is due to the increase in no. of crows "survival of the fittest" i think crow dominated sparrows what do you think?

I noticed that too, When I was a kid there are lots of Sparrows everywhere, But i rarely see them now, i guess its because the number of trees in cities were decreasing, they might have migrated to somewhere less civilized or maybe they were dying out. I dont know about crows because I dont see them neither, Cats were bigger suspects though because my cats killed a lot of sparrows and swallows.
