One evening last week I listened to a nightingale sing. It was about 8.30pm, and almost dark, in a block of scrub surrounding rough grass on the edge of a wood. The sky was mostly clear, and as the light fell it seemed to be backlit, with the moon up and the first stars appearing. All very romantic, except for the lights of airliners, the fields of flowering rapeseed, and the vaulting arch of high-tension power lines overhead. This is lowland England after all, not Keats’s ‘melodious plot of beechen green’. But it was still a nightingale.
This was not a chance encounter. A campaign called Nightingale Nights draws attention to the decline in nightingale numbers in the UK. I had never heard a nightingale in Britain, and it seemed a good challenge. It is not too easy. The website lists a set of places where you have a good chance of finding a nightingale. But they only sing from mid April to mid-May, and there are not many left. Numbers fell by 91 per cent between 1967 and 2007. The British Trust for Ornithology (BTO) volunteer survey in 2012 and 2013 recorded 3300 territories. With adjustments for areas not surveyed, this means there are 5,850 Nightingale territories in Britain, almost all in the south and east of England (with one hardy singer in Cleveland). How many singing males find a mate, and how many of these raise young, is anyone’s guess.
