[56] BIRDS OF OREGON 



Murie joined Jewett in September and worked with him about a year. 

 Until June 1916, Jewett put in parts of each year collecting and was 

 assisted by various wardens and temporary employees. A total of about 

 2.,ooo bird and 1,000 mammal skins were collected and are still the 

 property of the State Game Commission. This work, so well started, 

 was abandoned by Finley's successors, but the material has been available 

 for the present writers. 



Overton Dowell, Jr., has for many years carried on a limited amount 

 of collecting, largely in the vicinity of Mercer Lake in western Lane 

 County. The astonishing number of new distributional records that have 

 resulted from his persistent efforts are only an indication of what can be 

 expected from intensive work in other parts of this practically virgin 

 State. 



Since 1931, H. M. Dubois and John A. Carter, both of Portland, have 

 worked in the vicinity of that city, and Reed Ferris has been active in 

 Tillamook County. Their material and that of J. E. Patterson, who has 

 collected eggs for several years in Klamath and Jackson Counties, have 

 been incorporated in this book. Patterson has kindly loaned his manu- 

 script notes to the Biological Survey, and from these the present writers 

 have obtained much valuable information. 



Willard Ayres Eliot, an enthusiastic bird observer, incorporated his 

 own notes from the vicinity of Portland in his Birds of the Pacific Coast 

 (1913). This book, intended primarily for popular use, has furnished 

 valuable information and has stimulated an intensified public interest in 

 things ornithological, particularly in the vicinity of Portland. 



This completes the record of the more important workers in this field 

 of bird study, though a glance at the Bibliography (p. 609) will show 

 contributions from many other sources. 



WORK BY THE UNITED STATES BIOLOGICAL SURVEY 



IN ADDITION to the foregoing publications, specimens, and manuscript 

 notes on Oregon ornithology, the writers have had access to a vast mass 

 of unpublished data in the files of the Biological Survey, including reports 

 made and specimens collected in Oregon at various times for nearly 50 

 years by the many field workers and cooperators of that organization. 



Dr. Clinton Hart Merriam, first chief of the Bureau, visited parts of 

 Oregon in 1888, chiefly to study losses occasioned by rodents, and in 

 1896 he led the first exploration undertaken by the Biological Survey in 

 Oregon, with Vernon Bailey, E. A. Preble, and Cleveland Allen as 

 assistants. The party collected specimens of mammals and birds as a 

 basis for life-zone determinations in the Blue, Steens, and Warner Moun- 

 tains, and in the Cascades from the Klamath region north to Mount Hood. 

 About a month, from August n to September 15, was spent in the vicinity
