In 1933, Skokholm began as a bird observatory, the first in Britain, founded by Ronald Lockley; its prime function was the ringing of wild birds and research.   Lockley started the Pembrokeshire Bird Protection Society in 1938,  now incorporated in the Wildlife Trust of South and West Wales.  In 1948 the West Wales Field Society (WWFC), also now Wildlife Trust of South and West Wales, first took the Lease of Skokholm from the owners of the Dale Castle Estate.  Ringing on Skokholm ceased from 1976, and during the period of radar studies of migration around 1960 it became clear that bird movements as observed at the observatories were not representative of the whole, so significance of observatories in the study of migration waned. Skokholm had been the site of the most thorough British studies of the European storm petrel and razorbill amongst the seabirds and the Eurasian oystercatcher and the northern wheatear amongst the landbirds.   Skokholm Island was re-accredited as a bird observatory in 2014.  We thank Wikipedia for that, which sets the stage for this and a few following postcards.  Here is an unused real-photo card, and you may be excused if you wonder where the observatory is.  Grade: 1
