OHIO EXPERIMENT STATION. 



Mr. \V. E. Henderson mentions the discovery of a nest containing seven eggs,, 

 which seems sufficiently unusual to be worthy of record. 



The breeding Shrikes of this County are intermediate between Lanius ludovici- 

 anus and L. ludoricianus cxcubitorides, but judging from the specimens examined, 

 they appear on the whole to most closely approach the latter, and may, at least for 

 the present, stand as such. 



FAMILY VIREONID/E. VIREOS. 

 GENUS VIREO VIEILLOT. 



SUBGEXUS VIREOSYLVA BONAPARTE. 



138. 



Vireo olivaceus (LINN.). 

 Red -eyed Vireo. 



A common summer resident. Its spring arrivals, as noted, are from May 3 to 

 15, inclusive. The latest fall date is October 3 (1891), but the species generally dis- 

 appears in September. 



It affects both the uplands and the lowlands, but is for the most part confined to 

 the woods, breeding preferably in the timbered ravines and near the borders of the 

 forests. 



The Red-eyed Vireo sings steadily from the time of its arrival until about the 

 middle of August, and thereafter more or less intermittently usually as long as it re- 

 mains, the latest song date being October 3 (1891). 



139. Vireo gilvus (VIEILL.). 

 Warbling Vireo. 



An abundant summer resident; somewhat more numerous at the time of the 

 spring migration. It appears ordinarily during the first week of May, and remains 

 until late in September. Extreme dates are April 28, 1891, and October 2, 1892. 



In most situations excepting the woodlands, the present species, particularly dur- 

 ing the breeding season, replaces to a great extent the Red-eyed Vireo. It occurs 

 most commonly along the sparsely timbered portions of the streams, as well as in the 

 vicinity of rural dwellings and the well shaded streets of the towns. 



The nesting season is initiated during the latter part of May, and eggs may be 

 obtained at almost any time in June The breeding place preferred seems to be an apple 

 orchard, and the nest when thus located is usually from four to twenty feet from the 

 ground, but elsewhere is commonly at an altitude of between twenty-five and forty 

 feet. Aside from orchard trees, nests have been detected in maples (Acer rubrum), 

 n wild cherry trees (Prunus serotina) and in willows. 



The measurements of three nests are as follows :
