CONNECTICUT WARBLER.

and that the reverse is true in the fall. In spring migration it is found 

 west of the Mississippi River at St. Louis and to the Red River of Min- 

 nesota. It is not known from Nebraska, Kansas , or Louisiana, but there 

 is one record of its accidental occurrence in Colorado. It would seem 

 that the principal line of spring migration is from South America to 

 the Bahamas and undoubtedly to Cuba, though the species is not yet 

 reported from that island. 



The full record of the Connecticat warbler at the Sombrero Key 

 lighthouse in southern Florida is: 



Record of Connecticut warbler at Sombrero Key lighthouse. 



In 1893 the first spring migrants of this species were seen on the 

 lower Suwanee River <* May 10 and 11, and at South Anclote Key* 

 May 24, 1887. The next record to the north is in Chester Count^^ 

 S. C, May 10, 1889. The bird was seen at St. Louis May 14, 1883; 

 May 21, 1884, and May 16 and 22, 1885. Records are more common 

 in Indiana and Illinois, and are usually made about the middle of May, 

 the earliest date being May 4, 1891, at English Lake, Ind. The spe- 

 cies has been taken many times in spring in Michigan and Wisconsin, 

 and it can hardly be called uncommon in Minnesota from the Red River 

 on the west to the St. Louis River on the east. 



lall migration.— The Connecticut warbler is not known in Canada 

 east of Ontario, nor in New England north of Massachusetts, except 

 for a few specimens taken at Pittsford, Vt., September 20, 1888;'' 

 Shelburne, N. H., September 14, and Saco, Me., September 8-15. 

 From its breeding grounds in Manitoba and Ontario it seems to pass 

 south and southeast to the region of the Great Lakes and to the Atlan- 

 tic in Massachusetts. It has been taken at Chicago and in southern 

 Michigan August 30; Ossining, N. Y., August 26, and at Washington, 

 D. C, August 28. Most of the records of its occurrence in the east- 

 ern United States are made in September. Considering the small 

 numbers observed, it strikes the lighthouses with much frequency. 

 It has been reported as striking at Spectacle Reef lighthouse near the 

 Straits of Mackinac. It struck one of the exposition buildings at 

 Milwaukee «« September 22-23, 1888. Sixteen were killed on the 

 night of September 30, 1883, at Fire Island light,« and three at Shin-
