OF EASTERN PENNSYLVANIA. 19 



have known them to remain with us as late as the 

 first of November, when the season has been 

 unusually propitious. The same agreeable strains 

 are heard in the morning and evening twilight 

 during their autumnal stay, as marked their vernal 

 advent. 



The song of this Thrush is one of its most 

 pleasing characteristics. No lover of music can 

 fail to appreciate it ; and having ascertained its 

 source, no one can fail to recognize it when heard 

 again. The melody is one of great sweetness and 

 power, and consists of several parts. The con- 

 clusion resembles the tinkling of a small bell, 

 though ending somewhat abruptly. Each suc- 

 ceeding strain seems more pleasing than what 

 went before. The following language will convey 

 to the minds of our readers, a tolerably clear idea 

 of its syllabic expression: ki-ki-ke-wil-ah-tce, ke- 

 ivil-ah-ffiil, twitikl-ke-wil-ah-twilu, ke-wil-ah-tee, 

 ke-wil-a/i-tiiit, tur-kimllah. The ordinary call- note 

 is twni-ku-ku pronounced very quickly and with a 

 sharp intonation. 



The eggs of the Wood Thrush are usually four 

 in number. We have never observed five in a 

 nest, but have occasionally met with three. They 

 are of a uniform deep blue color, with enough of 

 yellow to impart a greenish tint. The average 

 measurement is .99 by .75 of an inch.
