Coauthors are listed separately under their name, with a reference to the annotated entry. In any instances I have inferred authorship, particularly where short items appeared in editorial columns. In these cases, I enclose the author's name in brackets. I have not used brackets where articles have been signed by initials and the identity of the author is clear. In cases where reference is untitled, I have created a title and enclose it in brackets.
Dates are inclusive.
Locations are listed in alphabetical order of counties. I list species within each annotation in phylogenetic order after the AOU check-list, 6th edition, 1983. I use th scientific names used by the author, but identify current scientific names, and use or identify current English names. I caution readers that nomenclature has changed markedly in the over 100 years covered by this bibliography. A good acquaintance with the species names used in Birds of Oregon will be helpful in discovering the early Oregon bird literature on your own.
