After some half an hour warm up in bed I started recording again. This time more birds and song more vivid. Luckily, there were no planes above. However, constant noise from printing works was still in the background.
This is the first bird singing. It was around 4am (no planes above). You’ll hear only song of one alone bird and roar of the city in the background: a factory printing today’s newspaper The Daily Mail (probably) and sound of many chillers, boilers and air conditioning devices.
