THE MYRTLE WARBLER has long been known as a migrant through Ore- 

 gon. Johnson (1880) first recorded it for the State in his list of birds from 

 East Portland, Forest Grove, and Salem. Keller (1891^ listed it from 

 Salem, November 2.6, 1891, and Prill (1892^) stated that it bred at Sweet 

 Home, a statement for which there has been no subsequent confirmation. 

 Woodcock (1902.) published records from Yaquina Bay, Salem, Portland, 

 and Corvallis. Shelton (1917) took a specimen near Eugene, March 18, 

 1915. Walker (19x4) recorded a specimen taken near Tillamook, April 

 2.8, 1919. We published a number of records for the Portland district in 

 our Birds of the Portland Area (Jewett and Gabrielson 192.9) and since that 

 date have continued to find it a regular migrant and at least an occa- 

 sional winter resident. In addition to these published records, which 

 include Multnomah, Washington, Marion, Linn, Benton, and Tillamook 

 Counties, there are manuscript notes in the Biological Survey files that 

 add Polk, Yamhill, and Clackamas Counties to the list, and we have 

 specimens from Jackson, Lane, and Multnomah Counties. The only 

 record east of the Cascades is of a male seen by Jewett on the Springer 

 Ranch near Malheur Lake, May 14, 1932.. The species arrives in October 

 (earliest date, October n, Multnomah County) and remains until May 

 (latest date, May 14, Harney County). 



While in Oregon, it is usually found intermingled with the much more 

 abundant Audubon's Warbler along the fence rows or in the deciduous 

 thickets along the streams. It is not conspicuously different from its 

 more familiar cousin, unless one can look directly at the throat, which is 

 white instead of bright yellow. As an opportunity for such a close view 

 is not always available, it requires careful search for the observer to pick 

 this bird out of the regular migrating warblers.
