In the spring of 1885 the first Blue Yeliow-backed Warblers were 
noted as follows: Houma, La., March 28; Gainesville, Tex., April 17; 
Saint Lonis, Mo., April 17; Chicago, Ill., May 9, and Milwaukee, Wis., 
May 5. It became common at Houma April 7, and at Saint Louis 
April 21. 
In the fall of 1885 it was last seen at Saint Louis October 6. 
649. Compsothlypis nigrilora (Coues). [89a.] Sennett’s Warbler. 
This warbler is known only from the Lower Rio Grande Valley in 
Texas, where it is a common summer resident (Sennett; Merrill), In 
the vicinity of Fort Brown it arrives about the third week in March 
(Merrill). 
650. Dendroica tigrina (Gmel.). [90.] Cape May Warbler. 
The Cape May Warbler winters south of our border and crosses the 
United States in its migrations to its northern breeding grounds. A 
few years ago the region east of the Mississippi was regarded as its 
home, and any record west of it was considered as accidental; but since 
more than two-thirds of the notes for 1884 came from the western side, 
the question arises whether the species may not be moving westward. 
Throughout most of the east it is rather rare, but in east-central Wis- . 
consin it has been found in great numbers, “hundreds seen in a day”; * 
in Minnesota it is stated to be very common in migration, and in west- 
ern Manitoba it is not rare. The most southwestern of the records is 
that from Pierce City, Mo., where it was found April 27,1884. Itreached 
latitude 42° 06’ May 5; was taken at West Depere, Wis., May 11, and 
by May 23 had arrived at Elk River, Minn. A female was taken at 
Lanesboro, Minn., May 21. It was also taken in Iowa, but the most 
interesting record is of its occurrence in Nebraska. Mr. Powell writes 
that at Alda, Nebr., May 12, 1883, he took an old male in good plumage, 
and a few days later three birds, probably of this species, were seen. 
In the spring of 1885 the few notes received on the movements of the 
Cape May Warbler indicate that its migration was very regular. 
“Firsts” were reported as follows: Saint Louis, Mo., May12; Delavan, 
Wis., May 14; Lanesboro, Minn., May 18; and Elk River, Minn., May 
20. A sudden cold snap stopped their migration and they took refuge, 
May 18, in the heavy timber near Lanesboro, Minn. Throughout 
the day they were exceedingly numerous. The next day not one was’ 
found. In the fall of 1885 they first appeared at Saint Louis, Septem- 
ber 9. 
651. Dendroica olivacea (Giraud). [92.] Olive Warbler. 
Inhabits the highlands of Mexico and Guatemala, coming north to 
Texas (Giraud) and Arizona. 
652. Dendroica zstiva (Gmel.). [93.] Yellow Warbler. 
After wintering below our southern border this species passes in sum- 
mer over the whole of the United States and Manitoba, breeding through-
