THE BIRDS OF WAYNE COUNTY.

Eight nests exhibit the following measurements : 



This species sings very persistently for the first few weeks after its advent in 

 spring, and quite regularly up to about the beginning of July, continuing more or 

 less intermittently until the last of this month. The latest song was recorded in 1891, 

 on July 28. 



146 Dendroica cserulescens (GMEI..). 

 Black-throated Blue Warbler. 



A common transient visitor ; much more numerous in spring than in fall. It is 

 however, somewhat irregular in numbers, being decidedly less frequent in some 

 seasons than in others. It appears usually during the first few days of May, and re- 

 mains for two or three weeks. It lingered late in 1892, being last observed on June 

 i. The earliest record of its arrival is April 23 (1893). 



It has been noted in the fall on but two occasions, October 5, 1890, and Septem- 

 ber 1 8, 1892. On the latter date one was seen singing. The Black-throated Blue oc- 

 curs with other of the Warblers in the thickets and woods of both the uplands ,and 

 the bottoms. 



147. Dendroica coronata (LINN.). 

 Myrtle Warbler. 



An abundant transient visitor ; somewhat more numerous in fall than in spring. 

 It has been observed as early as April 16 (1893), but does not usually appear until 

 several days later. It remains until about May 22. In autumn it has been noted from 

 September 25 to November 6. The lowlands along the creeks seem to be favorite 

 resorts for this species, and during the fall it may there be found often in small flocks. 

 With the possible exception of Dendroica striata the Myrtle Warbler is by far the 

 most numerous of the transient species of the family. 



148. Dendroica maculosa (GMEL.). 



Magnolia Warbler. 



A transient visitor; one of the less frequent species. It is sometimes tolerably 

 common, but has been observed only between May n and May 22. It is apparently
