A typical House Wren dummy nest, found in a slot box. Notice the loose arrangement of sticks, it does not fill the box, no nest cup, and no spider cocoons.
Dummy nests are placed in a variety of nestboxes by the male House Wren. The female chooses the box and them reconstructs a nest.
The student of Nature wonders the more and is astonished the less, the more conversant he becomes with her operations; but of all the perennial miracles she offers to his inspection, perhaps the most worthy of admiration is the development of a plant or of an animal from its embryo.
