Another important early work is "A History of British Birds" by Thomas Bewick, published in two volumes. Volume 1, "Land Birds", appeared in 1797. Volume 2, "Water Birds", appeared in 1804. The book was effectively the first "field guide" for non-specialists. Bewick provides an accurate illustration of each species, from life if possible, or from skins. The common and scientific name(s) are listed, citing the naming authorities. The bird is described, with its distribution and behaviour, often with extensive quotations from printed sources or correspondents. Critics note Bewick's skill as a naturalist as well as an engraver.
