In the summers of 1951 and 1952 some data on birds were gathered incidental to a study of the mammals of the Arctic Slope of northern Alaska (see Bee and Hall–Mammals of Northern Alaska …, Univ. Kansas Mus. Nat. Hist., Miscl. Publ., 8, March 10, 1956). Other students, currently preparing comprehensive accounts of the birds of northern Alaska, have urged that the information obtained in 1951 and 1952 be made available. For that reason, and because relatively little is on record concerning birds of the area visited, I have prepared the following account. The aim is to include only non-published data because the comprehensive accounts alluded to above, by others, can more appropriately include data from previously published accounts.

The area is the treeless tundra delimited by the crest of the Brooks Range to the south, the international boundary to the east and the Arctic Ocean to the north and west.

Three hundred and fifty-one birds of 44 species (Nos. 30371-30866, and 31301-31355) were collected. Twenty-nine additional species were seen. All specimens are skeletons, unless otherwise noted in the text, and are catalogued and housed at the Museum of Natural History, University of Kansas. Photographs are by the author.

The report results from a contract (Nonr-38700) between the Office of Naval Research and the Museum of Natural History of the University of Kansas. Field headquarters were at the Arctic Research Laboratory at Point Barrow, Alaska. Professor John Fields and Dr. Louis O. Quam of the Office of Naval Research, Professor Ira L. Wiggins, Scientific Director of the Arctic Research Laboratory, and Mr. M. R. Lipman of the University of Kansas Regional Office of the Office of Naval Research are four of the persons to whom I am deeply indebted. J. Knox Jones, Jr., and Edward G. Campbell, students at the University of Kansas, participated in the field work and deserve credit for a large part of the accomplishment registered in the field.
