We completed the review of Davis Creek audio files. The acoustic recorder collected over 500 hours of sounds between February 16 and March 23. The recording schedule targeted nocturnal species, but allowed for a brief overlap into the daytime hours.

We compiled all the owl calls to determine if they vocalize more frequently at certain times. The graph below plots all four species together.
