I was testing my new Telinga mic and It was rather late at night. I was placing some microphones in the Eastern Storfjellet skree. Just heading back to the cabin, the Puffins were murmuring all around me. It was one of those slightly mirky nights where the Puffins love being active; after midnight, and a bit rain.
I decided to put the Telinga parabol microphone down towards the rocks around me, and it resulted in a real strangely detailed recording.
The vocabulary of the Puffin vocalization is much more complex than what is described in my bird books.
I think that is something to keep in mind in general. Each creature on earth is much more complex than what a book can manage to speak to <3
