We record our observations on natural eutrophication and associated fish kill in a natural lake, caused entirely by roosting aquatic birds. Phosphate import via bird droppings led to monospecific blooming of the green alga Chlorella sp. in the lake void of any human interference, paving the way for bottom hypoxia and large-scale fish kill.
