Question

how did dwindling audience affect the nightingale

Answer 1

As the Frog started taking advantage of Nightingale's voice, more and more people came to attend the Nightingale's concert each day.  As the days passes, the frog was jealous of Nightingale and kept shouting at her. Due to this the Nightingale became nervous and as a result she was not able to sing properly. The crowd got bored of Nightingale's poor performance and the income of the frog also decrease. The frog started blaming the Nightingale and pressurized to sing but she could not sing as she became used to the crowd appreciation. At the end her lungs were puffed and veins were burst, and she died.
