Charles C. Abbott, Travels in a Tree-top
“ What is a bird’s nest? Every one knows, after a fashion, and yet few have ever considered how much that bunch of twigs, hollow in a tree, or hole in the ground really means. Like so much that is familiar, we glance at it in a careless way and never stop to consider its full significance. Except in a very few instances, a bird’s nest is never the result of a single individual’s labor. Even if but one bird does all the work, there has previously been a decision reached by two birds as to where the nest shall be placed, and how much this means! ”
