Produce a detailed written description of a dreary scene outside a swamp with frogs, ferns, and a bird.

Great clumps of horsetail ferns sprout among the willows here. The trees are thinner and more widely spaced, though they still grow close enough and thick enough to block your view after only a few feet. Somewhere nearby, frogs croak in an irregular chorus. Among the ferns, a lone bird calls, the sound echoing dully in the wet air.
