158 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB 



268 [628] Lanivireo flavifrons (VieilL). 



Yellow-throated Vireo. 



Common summer resident. May 6 to September 12. 



On May 18, 1919, a bird that sang the wild clear song of the Blue-headed 

 Vireo so that there seemed to be no mistake about its identity turned out to be a 

 Yellow-throated Vireo. 



269 [629] Lanivireo solitarius solitarius (Wils.). 

 Blue-headed Vireo. 



Uncommon summer resident, rather common transient visitor. April 23 to 

 October 10. 



Eggs: May 19 to May 21. 



While I have heard the Yellow-throated Vireo sing like a Blue-headed Vireo, 

 so also I have heard the latter bird sing like the former. 



Twice I have been favored with a sight of the courtship performance. The 

 male puffs out his yellow flank feathers very conspicuously and bobs and bows to 

 the female, very slim in contrast, and sings repeatedly meanwhile with many 

 variations to his song. 



On July 9, 1905, Mr. F. H. Allen found this bird at Boxford where it prob- 

 ably was breeding. 



270 [631] Vireo griseus griseus (Bodd.). 

 White-eyed Vireo. 



Rare summer resident, locally. May 5 to September 29 ; average date of 

 arrival for nine years. May 15 (A. P. Stubbs). 



Eggs: May 22 to June 18. 



In addition to the one locality, Swampscott, given for this bird in the original 

 Memoir, I have records from Lynn, Salem, Peabody, and one from the northern 

 part of the County from Amesbury. This last record is one of Mr. B. F. DamselU 

 who records that on July i, 1890, he shot one at Amesbury.
