xlii MIGRATION IN MAN 
MIGRATION IN MAN. 
THE Manx coast-line, extending lengthwise down the 
centre of the Irish Sea, undoubtedly lies in the course of 
migratory movements, and supplies a convenient resting 
place for birds, other than the proper residents, on their way 
along and across that sea. 
In this connection should be studied the report of 
the British Association Committee (1896) on the general 
results of its observations on migration, and especially the 
remarks (pp. 8 and 9) on the west coast of Great Britain, 
where is described a main route of migration passing from 
the Outer Hebrides by Dhuheartach, Islay, Wigtownshire, 
the Isle of Man, Anglesea, the South Bishop, and south- 
west England, being joined in many places by considerable 
contributories. The coasts of Cumberland, Lancashire, 
and north Ireland are little affected by this stream of 
migration. The west of Britain is also affected by a 
movement to and from the Faroes, Iceland, and Greenland 
(op. crt. p. 7). 
The subject of migration, however, is here, as elsewhere, 
in its details one of great difficulty, and although many 
notes derived from the Migration Reports to the British 
Association (1880-87) will be found under the specific 
headings, the writer, while awaiting the further elucidation 
of the mass of evidence thus gathered, does not consider 
himself competent to theorise upon its bearings on Manx 
ornithology. 
Species whose migration upon our coasts is very marked, 
are the Pied Wagtail, Wheatear, Curlew, Dunlin, and
