it is believed that a single herd of hooded seal.s inhabits
the waters of the North Atlantic. During the brc.eding, period the
animals coizcentra,te in two regions of drift--ice. nortl-:east of hewfoundland,

vary in longitude according to ice conditions in a particular year.
Hooded seals make regular mass migrations. After tne end of
the breeding period the main body of Newfoundland hooded seals, predominantly
consisting of adults,. crosses Davis '.trait; in i,iay thèy
approach the southern part of West Greenland in two waves, then travel
along the coast to the south and, passing Cape Farewell, appear in
June and July in Denmark Strait, where they form moulting, rookeries.
After producing young and. mating trie Jan Nayen Island hooded
seals migrate south along the marr,in of the ice-field on the east
coast of Greenland and appear in the Angmar-ssalik reL.ion in.June,
forming moulting rookeries east and northeast of that_point on the
coast of southern Greenland. Some of the Jan ;•:ayeri hooded seals' also^
mif,'rate into the northern parts of tne Gr;-enla.nd :>ea, where they form
moulting rookeries on permanent fields of drift-ice many years old.
These migrations are charactc:rirtic of adult and seVually-immature
animals in the sprin E.,r, although the aC;e-composition of tac mi{;rating
groups in different parts of the hooded seal range has not yet been
fully investi^;ated.
