[498] BIRDSOFOREGON 



the eastern edge of the timber, but records from farther east are doubtful, 

 probably being referable to V. c. celata. It appears in March (earliest 

 date, March 12., Lane County) and remains until September (latest date, 

 October i, Multnomah County). 



Baird (Baird, Cassin, and Lawrence 1858) published the first known 

 record for the State, when he listed two birds collected on the Columbia 

 River by J. K. Townsend, May 15 and 16, 1835. Although these might 

 have been taken on either shore of the river, the bird listed as taken at 

 Fort Dalles, May 4, 1855, by Dr. Suckley, and the one without date, but 

 certainly not much later, taken at Fort Umpqua by Dr. Vollmer, were 

 undoubtedly within the present limits of Oregon. Suckley (Cooper and 

 Suckley 1860) reprinted the record of the Fort Dalles bird. Anthony 

 (1886) considered the species common in Washington County; Merrill 

 (1888) listed it as a common migrant and stated that a few remained to 

 breed; and Finley (1904)3) published photos of nests from Portland. 



The eggs are laid in May. Our few dates and those published extend 

 from May 6 to June 3. V. Bailey found the birds feeding young near 

 Eugene between June 15 and 2.0, 1914. Woodcock (1902.) reported that 

 the Finley collection contained two sets of eggs taken May n and one 

 set taken June 3, 1895, at Portland. A number of later writers have 

 listed these warblers as breeding birds but give no definite data.

THE TINY CALAVERAS WARBLER is one of the common birds of the cut- 

 over lands of southern Oregon, being particularly abundant in the brushy 

 areas and in the oak-covered hillsides of Jackson, Josephine, and Klamath 

 Counties. It is less common but is found northward along the Cascades 

 to Portland. In addition, we have found it in Lake, Baker, Wallowa, 

 Sherman, Wasco, and Hood River Counties east of the Cascades and are
