MASS., ETC. 67 



ten or twelve feet from the ground. Arrives about May 

 5th, and is common till the last week of September. 

 Most abundant of the Vireos ; as numerous as all the 

 others together. 



91. Vireo gilvus Bonap. Warbling Vireo., Common. 

 Arrives first week in May and remains till last week of 

 September. Frequents orchards and gardens, and is very 

 common among the shade trees of the city, but is very 

 rarely seen about woods or thickets. Continues its song 

 throughout the season. 



92. Vireo (Lanivireo) solitarius Yieill. Solitary Vireo. 

 Quite rare. Probably some breed. Arrives in spring 

 about May 1st. Frequents open woods. 



93. Vireo ( Lanivireo ) flavifrons Vieill. Yellow-throat- 

 ed Vireo. Rather common, and breeds. Arrives second 

 week in May. Frequents open woods and the shade trees 

 of the city. 



Have never known the White-eyed Vireo ( V. novebora- 

 censis Bonap.J taken here, and if occurring, as it very 

 probably does, being not very uncommon in the eastern 

 parts of the State, must be excessively rare. In above 

 a thousand specimens of the smaller land birds taken at 

 Springfield during the last three years, by different col- 

 lectors, not a single White-eyed Vireo has been found. 

 Vireo philadelphicus Cass. may also occur, having been 

 taken the past season at Waterville, Me., by Prof. C. E. 

 Hamlin. (A. E. Verrill.) 



Of the thirteen species of Vireo described by Prof. 

 Baird as inhabiting the United States, only three ( V. oliva- 

 ceus, gilvus, flavifrons) are at all common here, but one other 

 ( V. solitarius) occurs, and perhaps two more ( V. novebo- 

 racensis and pliiladelpliicus ) will yet be detected here. All 

 but V. philadelpliicus, of the above mentioned, are known 

 to breed within the State. V. olivaceus is rarely seen 

 outside the woods, and gilvus as rarely elsewhere, while 

 flavifrons is common to both situations. 



94. Mimus polyglottus Boie. Mocking Bird. Very 

 rare. Appears to be its extreme northern limit. Have 

 been known to breed in Springfield several times within 

 five years, and in 1860 two pairs nested here. June 20th, 

 1860, I found a nest containing three freshly laid eggs,
