In the fall of 1885 the last was seen at Grinnell, Iowa, September 9. 

 Many were present at Saint Louis, Mo., September 21, and the last was 

 seen there October 10. Mr. Lloyd says it is an abundant summer resi- 

 dent in Tom Green County, Tex. 



625. Vireo flavoviridis (Cass.). [136.] Yellow-green Vireo. 



A bird of Mexico and Central America, coming north to the Lower 

 Eio Grande Valley in Texas, where a single specimen was taken by 

 Dr. Merrill, August 23, 1877. 



626. Vireo philadelphicus (Cass.). [138.] Philadelphia Vireo. 



This is not a common species in the Mississippi Valley, though ap- 

 parently more common here than in the Eastern States. Little is known 

 of its breeding range. A nest was found near Duck Mountain, Mani- 

 toba, June 9, 1881, by Mr. Ernest E. Thompson (Auk, Vol. II, 1885, 

 pp. 305, 306). In 1884 it was noted by two observers only — one at 

 Chicago, May 21, the other at Lanesboro, Minn., May 20. It has not 

 yet been taken in Kansas. 



In the spring of 1885 the first Philadelphia Vireo reached Saint Louis 

 May 8. The first record from Des Moines, Iowa, was May 14, and the 

 last was seen there May 20. At Lanesboro, Minn., the first was seen 

 May 18. 



In the fall of 1885 the first migrant returned to Saint Louis Septem- 

 ber 21, and the last was seen there September 27. 



627. Vireo gilvus. (Vieill.). [139]. Waroling Vireo. 



Common in Manitoba and throughout the Mississippi Valley ; breeds 

 throughout its range, and winters beyond our southern border. In the 

 spring of 1884 it arrived at Saint Louis April 19, and the bulk came 

 April 29. At this latter date the first came to Manhattan, Kans., fol- 

 lowed the next day by the bulk. This day (April 30) also brought the 

 first to Coral ville, Iowa, though few were seen until May 3. At Wau- 

 kou, Iowa, the first was recorded May 10, and the bulk May 18. The 

 first was seen at Lanesboro, Minn., May 18. They had previously been 

 noted (May 3) from Danville, 111., and (May 11) West De Pere, Wis. 

 At San Angelo, Tex., May 5 3 1884, Mr. Lloyd took two males, which 

 pertain to the form then known as V. swainsoni, but which is now con- 

 sidered to be not distinct from the eastern V. gilvus. 



In the fall of 1884 the bulk of Warbling Vireos left Williamstown, 

 Iowa, August 8, and none were seen after that date. 



In the spring of 1885, at Saint Louis, Mo., the first was seen April 

 23, and the bulk of males arrived next day. Their migration north of 

 Saint Louis was not quite so rapid. The first came to Manhattan, 

 Kans., April 27; to Paris, 111., April 28; Hennepin, 111., May 1; Waukon, 

 Iowa, May 13; Lanesboro, Minn., May 15, and Heron Lake, Minn. ? 

 May 19. 



In the fall of 1885 none were seen at Saint Louis, Mo., after Septem- 

 ber 22.
