Whales and Other Marine Mammals of Washington and Oregon

Patrick Colgan is Director of Research and Natural Lands at the Royal
Botanical Gardens.

The whales, seals, otters, and walrus of the coastal northwest are rich
elements of natural heritage. While other regional marine field guides
do cover mammals, these two guides provide comprehensive information for
the many naturalists who will welcome them. An in-depth introduction
covers the biology and natural history of the animals and human-related
dimensions including lore, whaling, and conservation (although the
International Whaling Commission was established in 1946, not 1948, as
stated on p. 28). The records given for length and such are impressive.
Features of responsible whale watching are laudably outlined. The
generous species accounts include, most helpfully, a listing of similar
species. Each group of species is introduced separately. The color
drawings and photographs are excellent. The clever layout includes easy
access to the species accounts plus glossary, index, and contact
information for relevant organizations.

Presumably marketing advice resulted in two very similar volumes
instead of one: since only one species is treated only in the southern
book while seven are unique to the northern one, buy the latter if you
are buying only one.
