1912'\ Notes on the Birds of Chapel Hill, X. C. 25 



59. Rose-breasted Grosbeak {Zamelodia ludoviciana) . 



One male observed on April 28, 1908, in the village. A rare 

 transient visitor. 



60. Blue Grosbeak {Guiraca caerulea caerulea). 



A not uncommon bird during the spring migration. Arrived 

 on the following days: May 9, 1908, May 9, 1909, May 1, 1910, 

 May 24, 1911. It is without doubt a summer resident here. 



61. Indigo Bunting (Passerina cyanea). 



A very common summer resident, the bird's average arrival 

 for three years being April 24 (earliest record, April 23, 1909, 

 1911). The Indigo is a persistent singer from the time of its 

 arrival until late summer. 



62. Scarlet Tanager (Piranga erythromelas) . 



In 1910 this was a rather common bird on the campus from 

 May 10 to 16. It was not seen at any other time. A rather un- 

 common transient visitor at Chapel Hill. 



63. Summer Tanager {Piranga rubra ruhra). 



This Tanager is the common form at Chapel Hill. It is a 

 resident in the summer. The extreme length of stay was from 

 April 15 (1909) to September 26 (1907). I found it to arrive 

 usually about April 20. 



64. Purple Martin {Progne suhis suhis). 



In 1908 this swallow, which is rather uncommon at Chapel 

 Hill, arrived on April 22. In 1907 one individual was seen on 

 September 7. I do not know of any that nest here. 



65. Barn Swallow (Hirundo eythrogastra) . 



Observed only in the spring of 1908, May 6 to 8, and in the 

 fall of 1909, September 17. On both occasions the birds were 

 migrating in flocks of eight or ten individuals. 



66. Rough-winged Swallow (Stelgidopteryx serripennis) . 

 The earliest appearance of this bird was on April 10, 1910. 



It is perhaps a rather uncommon summer resident. In the 

 migration season, however, it is more numerous, being seen reg- 

 ularly every year.
