Nightingales are very rare visitors to Shetland with only 7 spring records, the last one on mainland Shetland during this season appeared at Ireland, Bigton on the 25 April 2010 , with the majority of the 87 records from autumn birds.

Once you nip over to France, you can tell the difference, with birds even around the Calais area. The most abundant areas we have found , area down in the Camargue and over at Waghausel in Germany where they are abundant. Birds sing both day and night, although only unpaired males sing at night and I can listen to them all day. They generally can be found in song from April to early June. Its not often you see them as they tend to sing from deep inside bushes, but they have to come out to feed so its worth spending some time in the area to see them.
The song ` A nightingale sang in Berkeley Square' is much more likely to have been a Robin
