For many of us, isolation is disconcerting and challenging, but for wildlife sound recordist Chris Watson, it is something he actively seeks, so he can fully immerse himself in a place and capture its unique sounds in his recordings.

In the third of five illustrated essays, Chris vividly recalls his quest to capture the voices of a black throated diver or, 'musta kuikka', on an isolated lake in Finland having been inspired by a painting of Lake Keitele by Akseli Gallen-Kallela. Surrounded by a vast forest, he experiences a powerful sense and spirit of place as he watches, waits and listens.
