One of the saddest things I've seen in my life was when I was working in an orange grove on Merritt Island, Florida.  In that grove there were canals for irrigation and several pump-houses with big diesel pumps that pumped well water into the canals.  When my project started in the spring, the pumps weren't needed, since the rains were adequate for the trees.  In one pump house, a wren had built a nest, and we would look in on the baby birds as they grew.  At one point, before the babies were ready to leave the nest, that big diesel pump motor started to run.  The noise was deafening inside that pump house, and those wrens had no way to escape it.  My work was ending, and I never knew if those baby wrens survived.  Almost forty years later, I  still think about them.  Those wrens had no ability to recognize the danger of building a nest in a diesel pump house until it was too late.  We humans are smarter than wrens, but I'm not sure
