Excerpt from University of Kansas Publications, Museum of Natural History, 1970-1971, Vol. 19 The localities used as samples in this study vary in Size, shape, and geo graphic composition. In many cases I used museum specimens that had not been collected expressly for studies in geographic variation. It was therefore necessary to lump various localities together in order to obtain reasonable sample sizes. In many cases sample sizes are still relatively small, but I con sidered it to be of greater value to include information based on a few speci mens than to have no information at all for certain sites. A total of 54 samples, or localities, is used for most characters in males. And, since in Red-winged Blackbirds there have been fewer females collected than males, only 48 local ities could be used for most characters in females. A total of male and 679 female specimens have been used in the final analysis. In much of the discussion that follows, and in various illustrations, localities are referred to by number. The locality numbers, geographic details of each sample, and number of specimens per locality are given in Table 1 (see also Fig. About 600 specimens were collected by Mr. W. M. Good between 1949 and 1951 for the purpose of a study of geographic variation. About 320 speci mens were collected by me during the summer of 1966. These specimens, among others used, are housed at the University of Kansas. The remaining specimens were taken in various years by many different collectors and are now housed in several museums in the U. S. And Canada (see Acknowledgments section).
