Aeroecology is a new field of study looking at the ecology of life in the air. Many animals – birds, bats, and insects primarily — spend much of their lives aloft. This environment, the aerosphere, reaches from just overhead to miles high. There are no countries or borders, and the only highways are the winds. Most of it is beyond our human ability to study directly, especially at night, so aeroecology is one of the last frontiers of ecological study. I’ve collected information for you about some of the things we know about life in the air. Just click on one of the topics below to get started!
