CRC Handbook of Avian Body Masses

the long version

"In 1992 the CRC Handbook of Avian Body Masses broke new ground by providing a compilation of body masses for 6300 species, about two-thirds of the world's species. The handbook became the gold standard, cited in hundreds of scientific studies and a prominent fixture on the shelves of many ornithologists. Keeping the format that made the first edition so popular, the second edition features changes both in species coverage and the data quality." "The new edition compiles the results of new samples that have been published for many of the birds included in the first edition, and data found for about 2400 new species, increasing the coverage to over 8700 species, about 85% of the world's birds. The order of species and families has been revised in the text to fit with the latest publications in avian taxonomy and systematics. The second edition includes an accompanying CD-ROM with a searchable electronic database."--BOOK JACKET.
