VIREO FLAVIFRONS (VixEILLOoT). (628. ) 
YELLOW-THROATED VIREO. 
Somewhat rare, the Yellow-throated Vireo is still regularly 
a summer resident, breeding in its characteristic localities in 
the forests of the middle and southern sections, and without 
doubt as commonly in the northern. It arrives about May 
10th, and builds its nest about the 20th in forks of small 
branches some distance from the main trunk, and about twenty 
feet from the ground. This does not differ from that of the 
Red-eyed Vireo, being perhaps a little more artistic in its 
external finish, and employing a little more material. Of the 
general distribution of this species over the State I have been 
able to learn comparatively little. Dr. Hvoslef has identified 
him in Fillmore county; once as early as May 10th, and Mr. 
Lewis, in Hennepin, a little later, and a few have been 
obtained in the fall migration, early in September. 
No writer has ever given the male any flattering credit for 
his powers of song, indeed rather the opposite, but I must be 
permitted a different view of his vesper song at least. 
It was very near sunset, after a charming day, and I was 
about to leave the field and return home with my basket well 
filled with forms embracing several then new to me, when I 
caught the notes of a new songster, and paused in the growing 
shadows of the forest long enough to become enchanted by 
them. Was it the evening song of some familiar species I had 
failed to hear before, or had I been surprised by the revela- 
tions of a new candidate for my vote of admiration? He 
seemed entirely unconscious of my presence, indeed he was so 
far above me that I would scarcely expect him to be otherwise, 
and I therefore had all the opportunity I could desire to assure 
myself that he was unquestionably the source of the melody 
sonew tome. My field glass enabled me to get an excellent 
view of him, and after giving him every moment I dared, lest
