S;?erm !;!hale (:c'h?r, eter ca.todon)
t•Iintering srerin ?...,hales of the Asiatic herd are distributed.
-:IOStl?r in the lraters soui:h of the sout ern islands of 'a -, pan,
as the northern part of the Philippine Sea. Some groups of sperm
i•lilcl.leS, hot•Tevel" (sometimes even femwle.s with calves ),
remain through 176
the winter in the xe;ion of the southern Munie Islands. E arly in
spri:ng t-L).e whales begin migrating nort1rarard. :L'.•y A-pril they have
arrived at the Munie _I'sla.nds, whence some of them go farther to the
northeast and reach the Gulf of Kamchatka in May. The arrivals of
sper:a whales increase ciurin_,the f.ollowinE_,; months, and reach a peak
in July and August.
;i'clnales and juveniles also take aart in the migration, but
their movement »rcceed.s more slowly; a laxge nulnber of fe::i;:,les and
juveniles remain in the Z;rarm-water zone. l'hef go as far as Olyutorskii
Bay, f or ling concentrations in the region of Cape Govena and
haraginskii Island. The northern limit of the range of male sperm
whales is in the Cape 'Navarin region. Only in rare irlbta;nces have
sncrm whales been seen farther north.
The southward migration begins in September or October, and
usually follows the reverse sequence.
Some of the sperm whales in the American herd begin their
north;•,^ard movement as early as March (it becomes intensified in April
and Iyfay) along the wes.tern coasts of North America,
Some of them
turn west from Vancouver Island and enter the region of 50^ U,
1500 W, while others go into the Gulf Of Alaska. Fe-males N-rith calves
°
and juveniles are found there, sometimes as far north as 57 N.
S-Perm whales from the area south of 35° h and between 145 0 and 150 0 W
go north approximately as far as the 50th parallel.
The Hawaiian herd of sperm whales winters (as far .as is known)
i
northwest of the Hawaiian Islands, in the waters between 200 and
35° N and between 170 0 E and 160° W. Some of the whales in that
herd travel in summer to the eastern Aleutian Islands, whence some
enter the Bering Sea and possibly reach the coast of Asia, while
others go northeast to Kodiak Island and enter the northern part
of the Gulf of Alaska. Some whales nove to the west, and apparently
reach the I:omax.dors^cie Islands and even the Kurile Islands.
