While birds “neither sow nor reap nor gather into barns,” they most certainly do labor – particularly in the construction of nests. This being Labor Day in the United States we thought it therefore appropriate to stop for a moment and consider just what a monumental effort this actually is for them.
Using only their beaks either to chisel out or carry all the needed materials to the nesting site, each year millions upon millions of nesting birds create a structure that provides both shelter from the elements as well as protection and concealment against predators. Even if they nest in a box or birdhouse like these bluebirds, they still must build the actual nest inside it; the box is just the foundation.
It makes us tired just thinking about it. Thank goodness we have the day off today.
