“A few bats jerked and swooped against the stars, echolocating bugs. They should be hibernating by now and he wondered if they were sick with white-nose disease, staying out too long, desperate to build up calorie reserves that might or might not see them through the winter. No other creature perceived the world through echolocation in quite the same way as these microbats, and when they were gone, their umwelt would disappear forever. A universe snuffed out of existence.”
