In the spring of 1885 the first Blue Yellow-backed Warblers were 

 noted as follows: Houma, La., March 28; Gainesville, Tex., April 17; 

 Saint Louis, Mo., April 17; Chicago, 111., May 9, aDd 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 liigrilora (Coues). [89a.] SenneWs Warbler. 



This warbler is known only from the Lower Eio 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 breediug 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 siuce 

 more than two-thirds of the notes for 1881 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, 1881. It reached 

 latitude 42° 06' May 5; was taken at West Depere, Wis., May 11, and 

 by May 23 had arrived at Elk Eiver, Minn. A female was taken at 

 Lauesboro, Minn., May 21. It was also taken in Iowa, but the most 

 interesting record is of its occurrence in Kebraska. 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., May 12 ; Delavan, 

 Wis., May 14; Lanesboro, Minn., May 18; and Elk Biver, 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 aestiva (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-
