During this period too, I could not find any sparrows in our campus. So, I came to a conclusion that wherever I find sparrows, I find no squirrels, and vice-versa. In other words, the squirrels displace sparrows and do not co-exist. I would also say that the sparrow population is dwindling and the squirrel population is on the increase.
These are my personal views / findings over a wide range of period and if they are found to be true and acceptable, what the sparrows need to sustain their living is human dwellings and a squirrel-free atmosphere. Can the bird conservationists provide such a kind of natural environment? Also, more importantly, can this be done without harming the squirrels?
