Question

What did the early naturalists believe about the sudden disappearance and astounding
reappearance of the birds?

Answer 1

Answer:

This question has been worrying naturalists and avian enthusiasts of Mysuru who used to take up bird count in as many as 250 lakes around the city.

With waterbodies and wetlands disappearing fast or the lakes getting contaminated, the number of birds migrating to Mysuru has seen a drastic fall. Drop in water quality (entry of sewage) is another reason cited for the drop in bird count.
