THE BIRDS OF WAYNE COUNTY. 323 



A nest discovered on June 26, 1892, in an almost inaccessible position in an apple 

 tree, was ascertained to contain nearly fledged young. One of these had by accident 

 'become entangled in some of the external fibres of the nest, and having fallen, hung 

 suspended by the feet. This was indeed a very unfortunate position for the fledging, 

 and we undoubtedly earned its gratitude by affording it the relief which it had been 

 of course unable to obtain from its anxious parents. 



The Warbling Vireo sings regularly until about the first of August, and subse- 

 quently, though less frequently, until into September, the latest date of song heard 

 being in 1892, on September 23 This species has a curious habit of most unconcern- 

 edly singing although its home be quite closely approached, and it sometimes con- 

 tinues its song even while its nest is in process of being removed. 



SUBGENUS LANIVIREO BAIRD. 



140. Vireo flavifrons VIEILL. 

 Yellow- throated Yireo. 



Tolerably common as a summer resident, but most numerous in spring, arriving 

 ordinarily between the first and the seventh of May. It has not been observed later 

 than July 28 (1892), but it probably remains until at least the middle of August. It 

 is confined principally to the tall timber, being found on both the uplands and the 

 bottoms. 



It may be heard in song from the time of its appearance in spring until the latter 

 part of July. Its silence after the first of August perhaps accounts for its having 

 escaped any subsequent notice, since it is much oftener heard than seen. 



FAMILY flNIOTILTID/E. WOOD WARBLERS. 

 GENUS MNIOTILTA VIEILLOT. 



141. Mniotilta raria (LINN.). 

 Black and White Warbler. 



A common spring transient and very rare summer resident. It makes its ap- 



pearar^ce between the first and the fifteenth of May, and during the spring migration 



-frequents the woods on both the uplands and the bottoms, being often associated with 



other Warblers. In summer it has been noted principally in the wooded ravines 



.adjoining the lowlands. 



GENUS HELMINTHOPHILA RIDGWAY. 



142. Helminthophila pinus (LINN.). 

 Blue-winged Warbler. 



A rare summer resident; somewhat more numerous in spring, arriving between 

 the first and the tenth of May. It is seldom seen on the uplands, but affects chiefly 

 -the thickets of the bottoms. Owing no doubt to the character of the localities fre- 

 quented, it is generally heard rather than seen.
