In the spring of 1885 the Black-poll Warbler arrived at Saint Louis, 
Mo., April 29, several days earlier than it appeared at stations in the 
same latitude farther east and west. At Paris, Il., none were re- 
ported until May 4, nor at Manhattan, Kans., before May 12. One was 
seen at Des Moines, Iowa, May 5. Like many other Warblers, the 
Black-poll made a great advance from May 14 to May 16. Between 
these dates it was reported from Waukon, Iowa; Lanesboro, Minn., Elk 
River, Minn., and even from White Earth, Mis, , where as many as 
seventy-five rere seen May 16. At Saint Louls the bulk arrived May 
5; bulk left May 16, and the last one (a female) was seen May 22. It 
was not seen after May 20 at any other station from southern Missouri 
to southern Minnesota. 
In the fall of 1885 the arrival of the Black-poll at Saint Louis, Mo., 
September 21, was the only note received concerning its migration. 
662. Dendroica blackburniz (Gmel.). [102.] Blackburnian Warbler. 
Few lovers of forests and birds could fail to notice this brilliantly 
colored Warbler should they pass near its favorite haunts. It breeds 
from the heavy forests of northern Minnesota northward, and winters 
south of our southern border. Like the Chestnut-sided, it is rarely 
found so far west as Kansas and Nebraska. It is one of the few 
Warblers of whose entrance into the United States we have a record. 
In the spring of 1884 it appeared at Rodney, Miss., April 13; advanced 
to latitude-379 May 2; latitude 39° May 10; latitude 439 May 16; and 
the most northern record contributed was latitude 45° May 23. This 
gives an average of 23 miles a day for nearly a thousand miles. 
In the spring of 1885 the first Blackburnian Warbler was reported 
from Pierce City, Mo., May 7; from Saint Louis, Mo., and Hennepin, 
‘Il, May 12; from Lanesboro, Minn., May 16; and from Heron Lake, 
Minn., May 19. None were seen at Saint Louis after May 13. 
In the fall of 1885 the first was seen at Saint Louis September 19, 
and the last September 25. 
663 a. Dendroica dominica albilora Baird. [108a.] Sycamore Warbler; White- 
browed Yellow-throated Warbler. 
This form of the Yellow-throated Warbler is restricted to the south- 
ern portion of the Mississippi Valley, extending up to southern Indiana, 
sonthern Illinois, and Kansas. Evidently it does not breed in the 
Lower Rio Grande Valley in Texas, for Dr. Merrill says of it there: 
“One of the first migrants to return in the autumn, when it is not rare. 
A few pass the winter.” It is one of the carliest migrants among the 
Warblers, and in the spring of 1884 was reported from Saint Louis April 
4, and from Gainesville, Tex., April 7, showing how much later these 
insect-eating birds move on the plains than farther east. It was noted 
at Saint Louis that singing suddenly ceased April 30 and was recom- 
menced with great diligence May 31. 
In the spring of 1885, at Gainesville, Tex., the first Sycamore War 
bler was seen March 22; the next April 9, and the bulk April 17, At
