INFORMATION TO USERS This reproduction was made from a copy of a document sent to us for microfilming. While the most advanced technology has been used to photograph and reproduce this document, the quality of the reproduction is heavily dependent upon the quality of the material submitted. The following explanation of techniques is provided to help clarify markings or notations which may appear on this reproduction. 1.The sign or “target” for pages apparently lacking from the document photographed is “Missing Page(s)”. If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure complete continuity. 2. When an image on the film is obliterated with a round black mark, it is an indication of either blurred copy because of movement during exposure, duplicate copy, or copyrighted materials that should not have been filmed. For blurred pages, a good image of the page can be found in the adjacent frame. If copyrighted materials were deleted, a target note will appear listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photographed, a definite method of “sectioning” the material has been followed. It is customary to begin filming at the upper left hand comer of a large sheet and to continue from left to right in equal sections with small overlaps. If necessary, sectioning is continued again-beginning below the first row and continuing on until complete. 4. For illustrations that cannot be satisfactorily reproduced by xerographic means, photographic prints can be purchased at additional cost and inserted into your xerographic copy. These prints are available upon request from the Dissertations Customer Services Department. 5. Some pages in any document may have indistinct print. In all cases the best available copy has been filmed. Universi^ M icrailm s International 300 N.

Estes, Douglas W. Mock, W. Alan Nicewander, and especially the chairman, Gary D. Schnell, for assistance, critical review and patience during the tenure of this project. I benefitted considerably from discussions with a number of fellow students, particularly Robert D. Owen. I wish to thank the curators of a number of museums (listed in the acknowledgments in the first paper) for permission to use specimens in their care. The following individuals helped considerably in the recording and checking of data: Phyllis J. Aldag, Kathy Allison, Barbara Frantz, Christine E. Wood, Christopher S. Wood, Darwin L. Wood, and Lawrence R. Wood. Karen M.S. Herbst, Nancy J. Perkins and Christoph Malczewski prepared the figures. Finally, I wish to thank my wife, Charlotte, for her support and assistance with most aspects of the work; without her presence this project would never have come to pass. This research was supported by a grant from the Frank M. Chapman Memorial Fund of the American Museum of Natural History. iv PREFACE The following dissertation is divided into three distinct parts each of which is designed as a manuscript to be submitted for publication. The first paper is a summary of the phenetic affinities expressed by those skeletal elements of the storks that were analyzed; it is basically descriptive in nature. The second paper presents a. new mathematical transformation for continuous mensural data to be used in phenetic studies; this transformation was used in the other parts of the study. The third paper contains comparisons between the phenetic morphologic results and the sim ilarities based on ritualized courtship behavior; nomenclatural recommendations are discussed. Papers I and III are to be submitted to the Annals of Carnegie Museum; paper II is to be submitted to Systematic Zoology. PHENETIC RELATIONSHIPS WITHIN THE CICONIIDAE (AVES) D. S c o tt Wood A b stra c t The major skeletal elements of all 17 species of storks were analyzed using techniques from multivariate statistics to assess the phenetic affinities within the family Ciconiidae. The common-part transformation and the use of taxonomic distances clustered by the unweighted pair-group method with arithmetic averages gave significantly more stable phenetic arrangements than the other methods used. My results are very similar to the classification of Kahl (1979b) at the generic level with the exception that Jablru is more similar to Ephippiorhynchus than would be indicated from Kahl's classification. Also, Kahl's placement of these two genera in the tribe Leptoptilini is not supported by results based on skeletal data; these genera are phenetically similar to the Ciconia species. Introduction The cosmopolitan avian family Ciconiidae is composed of the 17 species of storks (Table I, nomenclature from Kahl 1971a, 1972a). By 1901 there was agreement as to the membership of the family except for the Shoebill (Balaeniceps), which most authors considered to be in a separate family (e.g., Beddard 1886, 1896, 1901, Garrod 1875, 1877, 1878, Parker 1860, Weldon 1883) and is currently recognized as such (Kahl 1979a). The classification of Peters -2- (1931,
