Nocturnal migration is a fruitful, relatively unexplored area of ornithology which is peculiarly situated to benefit from modern technology. Automated recording extraction software, state-of-the-art microphone hardware, and an increasingly niched understanding of bird life history combine to yield fresh data as to the nature of avian nocturnal movement, including arrival dates, population dynamics, and the occurrence of under reported species. My own forays into this phenomenon have produced exciting results, which I hope to share in this presentation.

This presentation begins at the 3 hours 26 minutes mark on the video recording of the conference:  COA's Birds and the Environment Science Conference - Online - YouTube
