Unfortunately, Mother Nature played a very dirty trick on all the dead birds scattered around the lake

I don't know if birds have the ability to tell whether or not water is good for them by smelling or tasting it. One would guess they do. Unfortunately, Mother Nature played a very dirty trick on all the dead birds scattered around the lake. This is not bad water, this is perfectly good sulphuric acid, straight from the bowels of the volcanoes. The birds cannot even take off, they die at the spot where they had that fatal taste and soon get encased in mineral deposits.
