Midnight transient calls at Lime Kiln?

September 22, 2011

At the same time Jeanne Hyde was listening and recording these calls at Lime Kiln last night, Val’s monitoring software (WhoListener) detected the sounds. The low background noise makes it possible to hear the calls echoing around the steep rocky underwater canyon that is Haro Strait.

Does anyone concur that these are transient calls? Know which calls were made?
