Wayne: Birds of South Carolina. 211 



24. Wilsonia pusilla (Wils.). Wilson's Warbler. 



I can discover but one authentic record for the State. 1 This 

 species must, however, be a regular migrant in the Piedmont 

 region. 



Wilson's Warbler breeds from northern Maine northward to 

 Labrador and the regions about Hudson Bay, and winters south 

 of the United States — Yucatan to Costa Rica. 



25. Wilsonia canadensis (Linn.). Canadian Warbler. 



Mr. Loomis says ' concerning the Canadian Warbler: 



Rare or casual in fall (September) ; not uncommon at times in spring (first two 

 weeks of May) , when they render themselves conspicuous by their frequent sing- 

 ing. 



Although Mr. Brewster" found this bird breeding in the moun- 

 tains of western North Carolina at an altitude from 3000 feet 

 nearly to the top of the highest peak, Mr. Loomis did not 

 detect it at Mt. Pinnacle (3436 feet) nor at Caesar's Head (3218 

 feet), which is certainly remarkable. 



The Canadian Warbler breeds as far north as Labrador, and 

 its winter home appears to be chiefly Ecuador and Peru. 



26. Sitta carolinensis Lath. White-breasted Nuthatch. 

 This nuthatch is a permanent resident in the interior of the 



State and is common on the tops of the highest mountains. The 

 birds which breed along the coast, I have referred to the form 

 S. c. atkinsi, but they are not, in every respect, typical of that 

 race, being intermediate between carolinensis and atkinsi in re- 

 gard to the black on inner web of second and third tertials. A 

 specimen (apparently an adult male) taken February 16, 1907, 

 near Charleston, has the black area extending to the shaft of 

 both of the second tertials, while the third tertials are marked 

 as in typical carolinensis. The majority of birds taken are inter- 

 grades, but some are almost, if not quite, typical of atkinsi. 



The White-breasted Nuthatch ranges as far north as Fort 

 Churchill, Keewatin. 



27. Psaltriparus minimus (Towns.). Bush-tit. 



Mr. Leverett M. Loomis records this diminutive species for 

 the State on information furnished him by the late Dr. Cornelius 



i Loomis, Auk, VIII, 1891, 172, Chester, May 10, 1887. 2 Ibid, VIII, 1891, 172.
