Went to the Fynn Valley in search of nightingales, but no dice. It was the Oak Tree dawn chorus walk, which doesn’t sound right for a bird with Night in it’s name, but they do sing in the morning too. Just not where I was. However, a Cuckoo was present, which I personally haven’t heard round here before. It was a chance to try out the Perl script to synchronise the audio recordings and location, which worked well.
