to illustrate slightly the movements of birds generally, giving the ear- 

 liest and latest dates as indicating the two extremes of the migratory

While this report is based largely upon my notes, made principally 

 in southeastern Indiana within the past twenty-one years, I have also 

 had the benefit of the material that has come into my hands as the 

 curator of the Department of Ornithology of the Indiana Academy of 

 Science. Dr. C. Hart Merriam, chief of the Biological Survey of the 

 U. S. Department of Agriculture, has very kindly afforded me facil- 

 ities for examining the migration reports in his office from Indiana 

 for a series of years. He has also arranged to supply such cuts as are in 

 the possession of that department for the purpose of illustrating this 

 report. 



I have been favored with the assistance of Mr. Eobert Eidgway, 

 curator of the Department of Birds of the United States National 

 Museum; Dr. J. A. Allen, American Museum of Natural History, New 

 York; Dr. F. W. Langdon, Mr. Charles Dury, Mr. H. W. McBride, 

 Cincinnati, 0.; Mr. Ruthven Deane, Mr. H. K. Coale, Mr. J. G. Par-

 Hine, Sedan; Mr. E. J. Chansler, Bicknell; Messrs. L. A. and C. D. 

 Test, Lafayette; Prof. II . S. Voorhees, Brookville, and Miss Lulu 

 Ward, Milton, and of a great number of patient investigators who, for 

 the love of nature and the desire to advance knowledge, have made 

 careful observations and submitted valuable reports. Towards the end 

 of this paper I have attempted to mention them by name, and I sin- 

 cerely hope I have omitted none. To each one I extend my thanks 

 for the assistance rendered. 



In addition the J. B. Lippincott Company have kindly given me 

 permission to make use of the keys in Ridgway's Manual of North 

 American Birds. A. C. McClung & Company have granted 

 the same permission regarding Dr. Jordan's Manual of Vertebrates, 

 and Dr. Elliott Coues has authorized me to make use of his Key to 

 North American Birds. I am indeed thankful for the courtesy ex-
