Lanivireo solitarius cassini. Cassin's Vireo. — Douglas Spring, Routt 

 County, September 4, 1906 (Cary); Silverton, October 21, 1893 (Loring); 

 near Creswell, Jefferson County, September 9, 1887 (Smith); near Denver, 

 September 16, 1884 (Smith). 



Lanivireo solitarius plumbeus. Plumbeous Vireo. — Solitary Vireos, 

 presumably of this form, have been seen at Yuma in May of both 1905 and 

 1907 (Patten). 



Vireo belli. Bell's Vireo.— One, Denver, June 12, 1903 (Smith). 

 This is the first record for Colorado. Later it was found as & fairly common 

 breeder along the eastern edge of the State at Holly, Wray and Julesburg 

 (Smith). One at Yuma, May 8, 1906 (Patten). 



Vireo vicinior. Gray Vireo. — Four specimens were taken at Lamar, 

 May 16-20, 1907 (Smith). This is the first and only record for Colorado 

 and an extension two hundred miles to the northeast of the previously 

 known range. 



Mniotilta varia. Black and White Warbler. — One May 23, 1907, 

 at Holly (Smith). 



[Protonotaria citrea. Prothonotary Warbler. — Has been credited 

 to the State (Auk, XXIV, 1907, 342) on the strength of three specimens 

 said to have been taken near Monument and at Pueblo. There is evidently 

 a mistake in the locality where the specimens were obtained for the Pro- 

 thonotary is a swamp warbler and would find no congenial surroundings 

 near Pueblo to say nothing of the pine clad lulls of Monument. The 

 species better wait for further proof, before it takes a place in the Colorado 

 list.] 



Vermivora chrysoptera. Golden-winged Warbler. — One May 25, 



1906, at Yuma (Patten). This is the first record for the State. 

 Vermivora virginise. Virginia's Warbler. — A large extension of the 



known range to the eastward is the result of the one taken May 3, 1905, 

 at Monon, Baca County (Warren). 



Vermivora peregrina. Tennessee Warbler. — Two, May 20-21, 1904, 

 Wray (Smith); abundant at the same place May 21-23, 1909 (Cary). 

 Common May, 1907, at Holly, Manzanola, Kit Carson and Julesburg 

 (Smith). 



Compsothlypis americana usneae. Northern Parula Warbler. — 

 One near Denver, May 5, 1904 (Smith); a flock of about a dozen May 27, 



1907, at Kit Carson (Smith). 



[Dendroica aestiva sonorana. Sonora Yellow Warbler. — Later 

 investigations make it probable that all the Yellow Warblers of Colorado 

 should be classed under the one form cestiva. The above form sonorana 

 is therefore withdrawn from the State list.] 



Dendroica cserulescens. Black-throated Blue Warbler. — One, 

 September 18, 1903, Wray (Smith). Seen at Yuma, September 19, 1904; 

 September 10, 1906 and October 6, 1906 (Patten). 



Dendroica coronata. Myrtle Warbler. — One, December 31, 1907, 

 Holly (Smith). This is the first winter record for Colorado.
