Bird Droppings and Waste Disposal

If you ever found your car looking like the one in the picture, you know how frustrating it can be. Maybe you should have parked in a different spot. Seriously, bird droppings and waste disposal by all animals present many design challenges.

One of the major issues for all living things is how to dispose of waste. Left inside the body, waste products can be toxic. Surviving the toxic effect can be a significant challenge for a hibernating bear. For birds, it becomes complicated because they must remain lightweight to fly. They cannot have a waste removal system that is heavy or dense. That means there is no bladder and no elaborate intestinal tract in birds.

God has designed a system of waste removal in birds that we are all aware of, but may have never considered carefully. The next time you see bird droppings on your car or the sidewalk, take a close look. You will see that there is a dark spot surrounded by white material. The dark spot is fecal matter, and the white stuff is urine. The urine washes away quickly in the first rain, and the fecal matter remains. Waste removal systems frequently benefit other forms of life, and that dark spot may contain seeds that contribute to the spreading of plant life.

Some birds have unique disposal systems such as owls, which make pellets out of solid material they eat, including bones. The birds that decorate your car are specially adapted to flight. The design of their disposal system allows them to be rulers of the sky. Birders are probably familiar with a periodical put out by a humorous writer who called himself Dick E. Bird. Years ago, he wrote this poem to explain how birds defecate:

“Birds, ya know, don’t got no bladder,
So wherever they is, it just don’t matter.
On the deck or on the sills,
The spirit moves, you hear a trill.
Then they fly, just like a thief,
That is how they spell relief.”

God intelligently designs every living system, and waste disposal systems are no exception. Bird droppings and waste disposal from animals also require clean-up after the fact, and God has that covered too, as we have discussed before.
