warm days in December and January it occasionally bursts 

 into song. It continues to sing until October. 



82. Prairie Warbler (Dendroica discolor). 



A common summer resident in the thickety hill-sides around 

 Chapel Hill. My records for spring arrivals for four years all 

 lie between April 14 and April 18. In 1907 it was noted on 

 September 15. 



83. Oven-bird (Seiurus aurocapillus) . 



This bird appeared in the spring during my four years stay 

 from April 10 to April 21. It is without doubt a summer resi- 

 dent ; during the migration it is common, becoming only toler- 

 ably common later in the year. 



84. Louisiana Water-thrush {Seiurus ynotacilla). 



This warbler is a resident at Chapel Hill. It appeared in 

 the spring as follows: March 29, 1908, April 15, 1909, March 

 24, 1910. In 1907 it was seen on September 6. 



85. Kentucky Warbler (Oporornis formosus). 



This bird, which is a rather uncommon summer resident, was 

 first observed in 1909 on May 18. It was noted quite frequently 

 in the woods south of the campus. It has not been hitherto listed 

 as occurring at Chapel Hill.

 The first migrants were noted as follows: April 4, 1908, 



March 29, 1909, April 2, 1910, April 23, 1911. In 1907 it 

 was last seen on October 14, in 1908 on October 19. I found 

 it not very common at Chapel Hill. It breeds here. 



87. Yellow-breasted Chat (Ideria virens virens). 



A very common species, resident in summer. Its appearance 

 was as follows: April 21, 1908, May 9, 1909, May 1, 1910. 

 In 1911 I saw none of these birds, although I looked for them 

 carefully until my departure on May 30.
