44. Pine Siskin (Spinus pinus). 



This uncommon transient visitor was noted in abundance on 

 the campus from April 23 to May 6, 1911. These are the first 

 recorded at Chapel Hill. 



45. Vesper Sparrow (Pooecetes grmnineus gramineus). 

 First seen in 1908, on October 30 ; was seen in December ; 



and on April 3, 1909. A rather uncommon winter visitor. 



46. Savannah Sparrow {Passer cuius sandwichensis savanna). 

 I only saw this bird in the spring of 1909. It occurs probably 



as a regular winter bird. I found it common in the arboretum 

 from April 2 to April 23. One individual was heard to sing on 

 April 18. 



47. Grasshopper Sparraw (Ammodramus savannarum aus- 

 tralis) . 



Observed only on May 30, 1908, and April 10, 1911. It is 

 not known to breed here, but probably does. 



48. White-throated Sparrow (Zonotrichia alhicollis). 



An abundant winter visitor. Length of stay: October 14, 

 1907, to April 11, 1908; October 16, 1908, to May 7, 1909; 



to May 5, 1910 ; October 13, 1910, to May 7, 1911. 



Sings during its entire stay, but most frequently in April. 



49. Chipping Sparrow (Spizella passerina passerina). 

 Abundant as a summer resident. Spring arrivals are as fol- 

 lows: March 6, 1908, February 28, 1909, March 9, 1910. It 

 usually leaves about ^November 10. On December 10, 1907, 

 however, quite a number were seen on the campus. 



50. Field Sparrow (Spizella pusilla pusilla). 



This common permanent resident begins to sing regularly 

 about February 14. One individual was heard as early, how- 

 ever, as January 22. 



51. Slate-colored Junco (Junco hyemalis hyemalis). 



The '' Snow-bird" is a very common winter visitor. The av- 

 erage date of arrival was November 10; the earliest, October 

 25, 1908. In the spring it was seen until April 15 in 1909.
