David Tomlinson, Country Life
"This sumptuous volume is the bargain bird book of the year, if not the decade...within its 392 pages is not only a complete and highly detailed account of the biology of the 19 storks, single shoebill, 23 ibises and six spoonbills, but also the most magnificent collection of paintings of these 49 species."
