In Seth's poem, the creatures really like the nightingale's song.  Seth describes this as a near universal appreciation from the creatures in the bog.  "Ducks had swum and herons waded" and while a loon "wept" out of pure love for the song being sung.  "Toads and teals and tiddlers," were all pleased with her song, as well.  Even when the nightingale was being put through her arduous "training," the "Owl of Sandwich" and "Duck of Kent" along with the Cardinal and Mallard all served as willing audience for all of her songs.  Yet, at some point, the over- saturation of the music and the songs sung by the nightingale began to take its toll on both her voice and the public appreciation of her work.  "Birds and beasts" eventually tired of her song and her efforts.  The poem does a very solid job of displaying how the public, in this case the animals of the bog, are by and large only concerned with the consumption of art and show very little interest in terms of appreciating the arist and showing respect to this end.  In the end, the creatures' responses of both appreciative consumption followed by eventual disregard both contribute to the rise and fall of the nightingale.
