Annual visitor to Foula in varying numbers. Mainly on Mill
The terrain makes access to some water bodies
difficult and therefore it is almost impossible to determine how many birds are
present on the whole island at any one time.
At least 50 birds have been present on the island in
past years – 3rd – 4th November, 1996 and mid October,
1997. Usually however, peak numbers range between 10 and 40.
