A list of numbers and kinds of birds killed is given in Table 1. Discussion of data afforded by certain species for which, large samples were available will be found below. There are additionally certain data afforded by the sample and certain comments to be made on various species which can be handled most conveniently in an annotated list. In this list we have included all weight data (still scarce for many North American birds), comments on status in Kansas of various species, results of comparisons to determine subspecies, and miscellaneous observations. Weights of birds are given in grams and were taken on a triple-beam balance. Fat condition is given in the scale proposed by McCabe (1943:556). Weight data from birds migrating at night should be especially useful because these migrants all have relatively empty crops and stomachs, thus reducing variability. Not all birds were suitable for weighing and measuring, for a variety of reasons. This accounts for discrepancies in totals between Table 1 and the annotated list. All passerine species were aged by noting the degree of ossification of the skull. In no case, of the more than a thousand passerines aged by examination of the skull, did we find difficulty in determining whether an individual was a bird of the year or an adult. We found no specimens in which ossification of the skull was nearing completion. In the several species in our sample with distinctive first-winter plumages, we found complete agreement in age as shown by plumage and by condition of the skull. We think this is further proof, if such is needed, that this method of aging is thoroughly reliable in early autumn for the passerine species included in our sample and for others with similar breeding seasons. TABLE 1.--BIRDS KILLED AT A TELEVISION TOWER AT TOPEKA, KANSAS, IN 1954 See annotated list for division into sex- and age-classes. Where discrepancies exist between totals given here and totals given in the annotated list, these result from the fact that some specimens could not be sexed and aged.
