Sterna fluvialis – A common migrant off the coast in spring and autumn.
We learn from the boatmen that there is a small colony of Common Terns on Skokholm Stack. In the spring of 1884, we were told that about twenty pairs might be counted there. Some Common Terns were seen on the Tuskar Rock on May 24th, 1883; and others were noticed passing to the south-west, until May 27th. Some of these birds may have been on their way to Skokholm.
