Inhaltsangabe

This study provides comprehensive and up-to-date information on all the features that make possible identification of all 62 species of sparrows that occur in North America. The text gives detailed descriptions of the summer, winter, and juvenile plumages of each species, as well as comparisons with similar species. The species accounts are illustrated with range maps and line drawings showing behavioural postures and, where useful, fine features of tail feather patterns. The 27 colour plates illustrate the various plumages of each species with the emphasis on the distinctive appearance of birds of different sex, age, and geographic regions.
