6 PACIFIC COAST AVIFAUNA No. 14 



Mr. Bernard Bailey, foi'iinM-ly of Corvallis. Moiitaua, now of Elk River. 

 Minnesota, has sent me a very complete list of the birds observed by him iu the 

 Bitterroot Valley. This comprises almost the only data T could obtain from 

 that part of the state. Mr. A. D. DuBois, of Button, hus sent me much informa- 

 tion on birds observed both at Button and at Belton, where he spent two sum- 

 mers. 1 am also further indebted to him for the use of a number of very excel- 

 lent photographs, which do much to make this paper attractive. Lieut. Joseph 

 Kittredge, Jr., formerly located at Missoula with the Forest Service, and later 

 in Prance with the regiment of Forest Engineers, has furnished notes from 

 Missoula and from many other parts of the state which his previous work gave 

 him opportunity to visit. Mr. Nelson Lundwall, of Bozeman, has sent me the 

 records of several species new to the Gallatin Valley, which are ])artieularly 

 interesting as extreme western records in the state. Mr. J. L, Sloanaker, of 

 Kalispell, has sent me many notes on birds in that vicinity and at Flathead 

 Lake. His notes are particularly valuable, as they supplement the previous 

 knowledge of summer birds in this region with knowledge of tiiose sjiecies 

 which occur in the migrations and in winter. Mr. Gerald B. Thomas, of Bill- 

 ings, whose friendship I made at Bozeman during my first year in the state, 

 has sent me the most recent of these manuscript lists, relating mainly to the 

 vicinity of Billings, a portion of the state from which very little was pi-evionsly 

 known. His notes on the breeding water birds of the lake basii: couiiti-y north 

 of Billings are of unusual interest; they have added many valuable records 

 and several new species to the state list. Mr. ('. F. Hedges, of Miles City, who 

 collected a large number of the birds now at the ITniversity of Montana in ilis- 

 soula, has renewed his interest in birds and has sent me the results of his recent 

 collecting. These results have added two new subspecies to the state list, and 

 have widened the known ranges of several other species and subspecies. 



In addition to the above lists, received direct from field observers, 1 have 

 received encouragement and assistance from ornithologists whenever it has 

 been needed and wherever I have turned. Dr. Louis B. Bishop has aided me 

 from the first, identifying subspecies of nearly all the liirds I have collected in 

 the state, and more recently those which Mr. Hedges has sent me. and grautiiig 

 me the use of both his library and collection in my search for records. The 

 late Wells W. Cooke, to whom 1 wrote of my intentioa to write a Montana list, 

 less than two months before his death sent me not only the information for 

 which I first wrote him but also a long list of references to publications on 

 Montana birds, many of which were new to me. It is interesting to know that 

 Cooke once contemplated living in Montana, and that he had gathered these 

 references with the idea that he might himself some day write a state list. 

 This eontribvition did much, both to complete my bibliography of the state, and 

 to give me previously unknown sources of information. Since Prof. Cooke's 

 death, Dr. H. C. Oberholser has sent me information from the records of the 

 Biological Survey, whenever I have requested it, showing the same spirit of 

 interest and helpfulness. To Prof. Morton J. Elrod, of the University of Mon- 

 tana, I am indebted for the opportunity to spend twq summers in bird study
