Casual records. — The majority of the cerulean warblers found east 

 of the Allegheny Mountains might be considered as casual. All 

 records for New England should as yet be so considered, though the 

 species has increased in eastern New York in recent years. About 10 

 individuals have been recorded in Massachusetts ; two in Rhode Island, 

 and one in New Hampshire. On June 2, 1924, one was collected at 

 Whitewater Lake, in southwestern Manitoba, the farthest north that 

 the species has been found. There are two records for North Dakota ; 

 one near Jamestown on May 28, 1931, and another near Minot on May 

 24, 1937. A cerulean warbler was recorded near Denver, Colorado, on 

 May 17, 1883, and a specimen collected on September 2, 1936, on 

 Cherry Creek in Douglas County. A bird "observed at the Mimbres 

 during the latter part of April" is the only record for New Mexico. 

 On October 1, 1947, a specimen was collected at the southeastern edge 

 of the Salton Sea in California ; and on October 2, 1925, a specimen 

 was collected near La Grulla in the Sierra San Pedro Martir, Baja 

 California. 



Egg dates. — Ontario : 3 records, June 2 to 13. 



New York : 22 records. May 29 to July 9 ; 15 records, June 1 to 4. 



Pennsylvania : 5 records, May 16 to 26.

HABITS 



Bagg and Eliot (1937) give the following account of the history of 

 the naming of the Blackburnian Warbler : 



Some time in the later eighteenth century, a specimen (apparently female) was 

 sent from New York to England, and there described and named for a Mrs. 

 Blackburn who collected stuffed birds and was a patron to ornithology. Black- 

 burniae — Gmelin's latinization, in 1788, of this English name — was its scientific 

 designation until quite recently, when in an obscure German publication, dated 

 1776, were discovered a description of a specimen from French Guiana (which 

 is well east of the species' normal winter range), and the name fusca, blackish. 

 Wilson recognized the male as a rare transient near Philadelphia, but when he 

 shot a female (apparently, though he called it a male) in the Great Pine Swamp, 

 Pa., he named it Sylvia partis, the Hemlock Warbler. Audubon, too, considered 

 the Blackburnian and Hemlock Warblers distinct."
