Pipilo fuscus mesoleucus. Canon Towhee. — Abundant November. 

 1907, at Gaume's Ranch in northwestern Baca County and noted to the

 eastern records in the State, though the species had previously been 

 reported almost as far east at Watervale, August, 1906, and April, 1907 

 (Smith). * The most northern record is that of the specimen collected at 

 Boulder March 17, 1895 (Smith). 



Oreospiza chlorura. Green-tailed Towhee. — Occurs in migration on 

 the plains almost to the Kansas line; common in spring in Baca County; 

 Monon, May 3, 1905, and Springfield, May 11, 1905 (Warren). Seen at 

 Yuma in the spring from May 3, 1906, to June 11, 1907, and in the fall 

 from September 24, 1904, to September 30, 1908 (Patten). 



Zamelodia ludoviciana. Rose-breasted Grosbeak. — A pair near 

 Loveland, June 1, 1902 (Burnett). 



Guiraca caerulea lazula. Western Blue Grosbeak. — Las Animas, 

 July 1892, not rare (Fisher); Wray, a fairly common breeder (Smith); 

 Yuma, seen each spring for the last five years, earliest May 17, 1907

 Springs, La Plata County (Gilman); to Trinidad (Fisher); and to Baca
