Porch perch

Having a mind curious about scientific stuff has helped me in many ways to understand the mysteries of life on earth. An example is shown above, a plastic chair on a wooden porch. The chair is obviously a popular spot for birds to pause for a sit-down and eliminate waste. Most folks would look at the droppings on the chair and the droppings on the porch below and break out the garden hose. But I look on the scene and get a much bigger picture brought on by my deep thinking skills.

I noted that the droppings on the deck are:
  1. Fewer than on the chair back
  2. To the north of the chair
It’s obvious. Birds resting on this chair are migrating. During migration it is important to keep your direction of travel in mind so you don’t get off course. At this time of year, more birds are migrating to the north than to the south, thus the droppings on the chair back are more abundant than the ones on the deck. It’s elementary…
