Your post attracts an ad for pest control. I wonder how long before someone complains of the noise it makes during the night and calls them in? Seriously though I have heard it too near Decima street/wilds rents. It is lovely to hear.
It's 1:15 am and I can hear a blackbird outside singing away - they have a beautiful song, and like Sarah, I'm wondering if the nightingale is really a blackbird. Nightingales don't usually arrive here until later in the year, and need a lot of woodland/hedgerow cover as they are ground nesters. They are getting quite rare.
