97. White-breasted iN^uthatch (Sitta carolinensis carolinensis) . 

 A very common permanent resident. The prolonged nasal 



song of this I^iithatch begins to be heard frequently about the 

 middle of January. The song period reaches its maximum in 

 March or April. 



98. Brown-headed l^uthatch {Sitta pusilla.) 



A not uncommon permanent resident. I have seen immature 

 birds of the year. 



99. Tufted Titmouse {Baeolophus hicolor). 

 This is a very common resident species. 



100. Carolina Chickadee (Penthestes carolinensis carolinensis) . 

 Like the Titmouse, a very common permanent resident. 



101. Golden-crowned Kinglet {Regulus satrapa satrapa). 

 Arrived in the fall on the following dates: October 15, 1907, 



October 16, 1908, October 21, 1909, October 12, 1911. This 

 species remains in the pine forests around the village until near 

 the middle of April (April 11, 1908, April 14, 1910). 



102. Ruby-crowned Kinglet (Regulus calendula calendula). 

 More of a transient visitor than a winter resident, being 



rather common in October and March. In 1907 it arrived on 

 October 24, in 1908 on October 25. It arrived for its spring 

 stay on March 18 and was seen until April 21 in 1909. Again, 

 in 1911, this Kinglet was noted until April 23. Its song is 

 often heard during the spring. 



103. Blue-gray Gnatcatcher (Polioptila caerulea caerulea). 

 This tiny bird comes usually from the south in the last part 



of March. The average date of its appearance was March 30 

 (earliest, March 22, 1908). It is a common smiimer bird. In 

 1907 it was seen as late as September 23. 



104. Wood Thrush (Hylocichla mustelina). 



This handsome bird and its sweet song are characteristic of 

 the campus in spring and summer. The extreme length of its 

 stay was from April 8 (1909) to September 23 (1907). The 

 average time of its appearance in spring was April 13.
