111. Vircosylz'a olivacca (Linnaeus) — Red-eyed Vireo. 



On May 21, 24 and 30, 1912, I saw several Red-eyed 

 Vireos in the trees along the bank of the jMiddle Loup and 

 at the base of the first range of hills. On August 28 and 

 30, the Species Avas noted again, as it had been from August 

 22 to September 3, in 1911. The breeding of the species 

 is probable, but, in the absence of definite records, un- 

 certain. 



112. Vireosylva gilva (Vieillot) — Warbling Vireo. 



On August 22, 1911, I saw a lone Warbling Vireo in a 

 thicket near the river and on May 25 the following spring, 

 in the same bit of undergrowth, I secured a female, also 

 a solitary bird. No indications were present during the 

 summer of the breeding of the species at this locality, 

 although R. li. AVolcott noted the bird in June, 1906, and 

 July, 1908. 



113. Vireo belli Audubon — Bell Vireo. 



The Bell Vireo is the commonest of the vireos which 

 occur at Halsey, and breeds commonly in the dense thickets 

 of plum brush, haw, willow and dogwood that line the 

 river bank in places. Only one nest was discovered. This 

 one was about a foot and a lialf from the ground in a haw 

 and was first found on June 1, luicompleted, and later, on 

 June 7, with the complement of four eggs. It was hung 

 in the usual semipensile manner and was constructed 

 of grasses, bits of corn husk and a few odd scraps of paper, 

 the whole stuccoed with filaments of spider web and lined 

 with fine plant fibers. 



These little inconspicuous vireos confine themselves to 

 the scrub thicket in the river valley whence their harsh 

 "cheeow" is often heard, especially when the birds resent 

 your invasion of their provinces. Their siong is a hurried 

 sequence of notes for which I have never found adequate 

 representation in syllables, but it harmonizes well with the 

 active, restless disposition of the creatures, which seem 

 never to be still for a moment but move continually about 

 through the network of brush, now appearing on one side 

 of the observer, now on the other, and frequently reviling 

 you with their queer explosive calls. 



114. Mniotilta varia (Linnaeus) — Black-and- White Warbler. 

 The "wee'zy-wee'zy-wee'zy-wee'zy-wee'zy - -"of the
