situations. The following note on the feeding habits of this species 

 is contributed by Mr. Bacon : "In the summer of 1886 1 saw one of 

 these shrikes kill a Yellow Warbler, and on May 10, 189 1, I saw a 

 ^Vhite-throated Sparrow impaled on a thorn, with a shrike perched 

 near by, so that it would seem that occasionally this species preys 

 upon small birds as does the Northern Shrike." 



I S3. Vireo olivaceus. Rkd-eyf.d Vireo. 



^'ery abundant as a summer resident, more numerous, indeed, than 

 ever observed elsewhere by the writer, and perhaps the most common 

 and generally distributed small bird on the Peninsula, frecpienting the 

 woodland and shrubbery. It was first recorded in 1900 on May 12, 

 becoming common a few days later, and not disappearing until Sep- 

 tember 27. Many old nests Avere observed. Mr. Bacon says it often 

 nests in the shade trees in the city. 



184. Vireo philadelphicus. Philadelphia Vireo. 



Fairly numerous as a transient visitant in spring and fall, having 

 been observed in the former season, in 1900, at dates ranging from 

 May 14 to 23, and in the latter from September 6 to 25. Its favorite 

 haunts were bushes and shrubbery, where its deliberate motions dis- 

 tinguished it from the warblers, with which it was wont to associate, 

 and its brighter colors and smaller size from the more common Red- 

 eyed Vireo. It could be approached very closely, manifesting no fear. 

 Its song was not heard. 



185. Vireo gilvus. Warbling Vireo. 



Probably occurs as a summer resident on the mainland, perhaps 

 nesting in the shade trees in the city, where it was noted on May 12, 

 1900. It was observed on the Peninsula in the fall only, on Septem- 

 ber I and 12. Mr. Sennett has a specimen taken as late as September 

 21 (1888). 



1S6. Vireo flavifrons. Yellow-throated \'ireo. 



Doubtless a summer resident, but not very common. One shot 

 May 4 was the first of the season in 1900, and the only one observed 

 by us on the Peninsula. On May 28 a number were seen in a strip of 

 woods along the lake shore near the " Head," where they were appar- 

 ently settled for the season. In 1S92 Mr. Paeon noted two specimens 

 on May i.
