species on September 2, 1907, which was as late as I found it 

 in the fall. 



75. Cape May Warbler (Dendroica tigrina). 



In the spring of 1909 this rare bird was tolerably common in 

 the oaks on the campus from April 26 to May 3. These are 

 the first recorded at Chapel Hill, and must be regarded as very 

 rare transient visitors. 



76. Yellow Warbler (Dendroica aestiva aestiva). 



Spring arrivals were: April 20, 1908, April 19, 1909, April 

 16, 1910, April 18, 1911. Last bird seen in 1907 on September 

 20. A tolerably common breeding bird. 



77. Black-throated Blue Warbler (Dendroica caerulescens 

 caerulescens) . 



Observed only once, on April 25, 1909, in the arboretum. 



78. Myrtle Warbler (Dendroica coronata). 



This warbler is a common winter visitor, reaching Chapel 

 Hill as follows: October 14, 1907, October 25, 1908, October 

 22, 1909, October 21, 1910. It becomes extremely abundant in 

 March, is less abundant in April, and leaves early in May. 

 (Latest observed. May 15, 1910.) 



79. Black-poll Warbler (Dendroica striata). 



I found this warbler a regular transient visitor, which, during 

 its stay, was almost abundant. It was recorded each year, the 

 earliest arrival being April 29, 1911, the latest May 7, 1908. 

 In 1910 it remained until May 22. Its song was heard during 

 its short residence very often. It was not seen in the fall. 



80. Yellow-throated Warbler (Dendroica dominica dominica). 

 An early spring migrant, whose coming was noted as follows : 



April 7, 1908, March 28, 1909, March 29, 1910, April 7, 1911. 

 In 1907 it was seen until September 14. It breeds and is tol- 

 erably common, — very common during the migrations. 



81. Pine Warbler (Dendroica vigorsi). 



A resident all the year and is very common at Chapel Hill. 

 It begins to sing regularly about February 15, although on
