In the fall of 1885 the last was seen at Grinnell, [owa, 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 
Rio 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. Littleis known 
of its breeding range. A nest was found near Duck Mountain, Mani- 
toba, June 9, 1884, by Mr. Ernest E. Thompson (Auk, Vol. IT, 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]. Warbling 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 Coralville, Iowa, though few were seen until May 3. At Wau- 
kon, 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, Tll., and (May 11) West De Pere, Wis. 
At San Angelo, Tex., May 5, 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 
29, 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, Il., April 28; Hennepin, Ill., 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.
