In the fall of 1885 the first reappeared at Saint Louis, Mo., Septem- 

 ber 3 ; they were scarce September 17, and the last left September 22. 

 Mr. Lloyd says it is an abundant migrant "all over western Texas from 

 April 2 to May 15, and from September 3 to 30." 



686. Sylvania canadensis (Linn.). [127.] Canadian Warbler. 



This handsome Warbler is less common in the Mississippi Valley and 

 Manitoba than farther east. It does not winter in the United States, 

 but breeds sparingly in the Northern States, and abundantly in Can- 

 ada. It has been known to breed in northern Illinois. It extends west- 

 ward only to the eastern edge of Kansas and Nebraska. It occurs in 

 southeastern Texas in migration, but is not common (Nehrling). In the 

 spring of 1884 it arrived at latitude 37° April 29, latitude 39° May 11, 

 and at Lanesboro, Minn. (lat. 43° 43') May 24. The last was seen at 

 Saint Louis May 21. 



In the spring of 1885, at Saint Louis, the first was seen May 11, the 

 bulk was present from May 13 to May 19, and the last left May 22. At 

 Lanesboro, Minn., the first was reported May 15, and at Elk Eiver, 

 Minn., May 16. In Wisconsin, it was first reported from Durand May 

 15; and from New Richmond, May 19. 



In the fall of 1885 the first returning migrant was seen at Saint Louis 

 September 22; while at San Augelo, Tex., one was shot from a flock of 

 six August 28. 



687. Setophaga ruticilla (Linn.). [128. J American Redstart. 



The Eedstart is a common summer resident of the upper half of the 

 Mississippi Valley and Manitoba. As far south as Kansas it is a com- 

 mon breeder. It does not remain in the United States during the winter, 

 nor does it cross our boundary before the first of April. In the spring 

 of 1884 the first record came from Saint Louis April 17, and the next, 

 from latitude 40° 08' in Illinois, April 27. The last day of the mouth it 

 was seen at latitude 39° 12' in Kansas. For the first week of May 

 there was not a record; May 8 it reached latitude 41° 36' in Iowa ; and 

 May 10, 11, and 12, it spread abundantly over the immense district from 

 latitude 41° to latitude 45° 25'. By May 28 it had crossed our northern 

 border and arrived at Portage la Prairie, Manitoba (lat. 50°). 



The great changes and diversity in plumage in this species enable 

 the observant ornithologist to note very fully the arrival of the different 

 ages and sexes. Thus at Saint Louis the following record was made by 

 Mr. Widmann: 



April 17, first old males; April 26, bulk of old males; April 30, first females; May 

 7, height of transient old males; May 9, height of transient females; May 11, first 

 one-year-old male ; May 16, young males more conspicuous than old males. 



This is one of the species in which the period of arrival at any locality 

 extends over several weeks, the bulk coming many days behind the 

 first. Hence, all notes of first and bulk on the same day are self-evident 

 mistakes. The bulk never arrives till a week after the first, and ten to 

 twelve days is the ordinary time.
