What is the resolution/dénouement in the story?

The story changes narrative perspective as Sylvia sees the heron’s nesting place. Her natural instinct overcomes the appeal of the money and the hunter, and forces Sylvia to keep the birds’ secret: she cannot ‘give its life away.’

The narrator gives the opinion that Sylvia has shown herself worthy of keeping the secrets of nature, and is better off with her life as it is, rather than following her stirring womanly desires.
