At various times since 1S83 students of Indiana University interested 

 in birds have Icept records of the migrations, breeding habits, etc., of the 

 birds within a radius of several miles of Bloomington. Twenty sets of 

 migration records, covering fourteen seasons, are on file in the archives 

 of the Biological Survey at Washington, D. C. 



Three lists of birds have been prepared by former students. 



W. S. Blatchley in 188() recorded the "Winter Birds of the Vicinity of 

 Bloomington, Indiana," in the Hoosior Naturalist I, pp. 169-171. 



B. W. Evermann published a list of "Birds of Monroe County, Indi- 

 ana," in the Hoosier Naturalist II. pp. l.^T-llo and 164. He enumerates 

 179 species. 



C. H. Bollman listed 192 species in an unpublished paper on file il^'the 

 Biological Survey. 



"The Hoosier Naturalist," in which Evermann's and BlatChley's lists 

 were published has long been extinct and the two papers are not ac- 

 cessible. 



Some of the above lists and part of the migration records were used 

 by Amos W. Butler in his "Birds of Indiana" published in the 22d Annual 

 Report of the Department of Geology and Natural Resources, Indianap- 

 olis. 1S97. 



Pertinent facts contained in the above sources have been brought 

 together in the present paper. They have been confirmed or supple- 

 mented by the author's observations extending through the last four 

 years. While the material presented is chiefly of local interest it contains 

 additions to our knowledge of the birds of Indiana and the more general 

 subject of bird migration. Wherever possible, the authority for any state-
