Paul Johnsgard: Cormorants, darters, and pelicans in the world. Smithsonian Institution Press 1992/93, 450p. Pds. 39. The first part of the book looks at the comparative biology starting with taxonomy, then ranging through comparative morphology and anatomy, feeding behaviour and foraging, before concluding with population dynamics and conservation biology. The bulk of the book is devoted to accounts of 32 species of cormorants and shags, two species of darters and seven species of pelicans. It is difficult to fault this volume as a work of reference, and as the first world-wide survey of these species it is sure to find shelf space on libraries around the world. However, it is a reference book, not a book that will be orrowed through or read for pleasure, says the reviewer (David Tomlinson). The colour plates are disappointing. 5603 Andrew Kitchener: Justice at last for the dodo. New Scientist 28 August 1993, 24-27.
