Produce a detailed written description of a dreary scene outside town with a bird's nest, twigs, and a flat roof.

This small area of the rooftop is relatively bare except for an empty bird's nest tucked into one corner of the storm drains. A few bits of eggshell still remain inside the random-looking bundle of twigs and bark. The roof is fairly flat in this area, only a slight angle directing rainwater into the trough lining its edge.
