One of Life's Principles is that life uses readily available materials and energy. This concept is pretty easy to understand and it's pretty easy to find examples of this on your doorstep. The squirrel that lives in your tree isn't traveling to the next village, let alone Alabama, in search of materials to build its nest; it is finding materials in a relatively small radius around its home. Similarly, a plant isn't getting energy to grow from a coal-fired power plant, it's harnessing the sun's energy. Aside from energy from the sun, what other sources of energy can you think of that are readily available? I'm betting that this bird has you beat in terms of creativity in finding a readily available energy source.
