Information in the Bird Division type collection database is from Type Specimens of Birds in the Collections of the University of Michigan Museum of Zoology By Robert W. Storer published July 6,1988 in MISCELLANEOUS PUBLICATIONS MUSEUM OF ZOOLOGY, UNIVERSITY OF MICHIGAN NO. 174 with additions current as of September 2002.

Introduction
In 1905, Charles C. Adams published a list of 44 "Types of birds in the Beal-Steere Collections of the University Museum, University of Michigan," as part of the Report of the Curator of the Museum to the Board of Regents, July 1, 1903 to July 1, 1904 (Univ. Bull., New Ser. 6(2), pp. 23-28, February 1905). In the 83 years since the publication of this list, the number of taxa represented by type specimens in the bird collections of the University of Michigan Museum of Zoology has grown to 321. It is therefore desirable to publish an up-to-date list of these specimens. The collections also include the first described nests and eggs of three species.

More than half of these taxa are from India and were described by Walter Koelz. Koelz frequently failed to publish the catalogue number and museum in which his types were deposited. In general, only holotypes or lectotypes are listed. Exceptions have been made in the cases of eight Philippine taxa, of which the location of type material has been in doubt, and of Dendroica potomac and Loxia curvirostra benti, for which allotypes are listed along with the holotypes.

Additional information about holdings is available at the UMMZ Bird division research collection and the Bird Division home page.

Type specimens of fossil birds in the University of Michigan Museum of Paleontology are not included in this list. Type material of birds in the UMMZ is not available for loan to other the institutions, but may be studied at this museum by qualified systematists. Abbreviations for museum collections mentioned in this list are: AMNH = American Museum of Natural History (New York), BM = British Museum (Natural History), FMNH = Field Museum of Natural History (Chicago), MCZ = Museum of Comparative Zoology, Harvard University, and UMMZ = University of Michigan Museum of Zoology.
