The island's name is believed to be
Old Norse in origin, referring to the large number of bird feathers found there. Like the nearby
Bass Rock, it has a substantial
seabird population, and is now an
RSPB reserve. The village of
Gullane lies to the south-west, and the nature reserve of
Yellowcraig and village of
Dirleton, to which parish Fidra belongs, are to the south. Remotely operated cameras on the island send live pictures to the watching visitors at the
Scottish Seabird Centre in North Berwick. Upon the island are ruins of an old chapel, or
lazaretto for the sick, which was dedicated in 1165 to St Nicholas. ==Nature and ecology==
