I was just watching an episode of the series "lost worlds with Monty Halls and Leo Houlding". A rather anticlimactic episode about scaling a mountain in Borneo. During the first 15 minutes they are traipsing through the Bornean jungle, and I would swear I'm hearing a screaming piha in the background. Now last time I looked, they live rather on the other side of the world... Could I be mistaken with another bird, or would this be another example of nice editing..?
