Blackburnian Warbler. Dcndroica blackbnrnia. B(i2. 



We might reasonably expect this rather large Warbler to 

 favor us with a robust song. On the contrary, he seems unable 

 to produce more than a shrill, thin song, which runs up the 

 scale to end in a high z. I can recall it \>y the syllables tsive 

 tsxi'c tszcc, te ze ze z-z. Mr. Minot detects some difference be- 

 tween the spring and summer songs. The summer song is a 

 repetition of the syllables zvee-see, with the accent on the sec- 

 ond ; while the spring song is more ambitious : wee-see, wee- 

 see, tsce-tsce, tsee, tsee, tsee-tsee, tsee, tsee, ending shrill and fine. 

 While the song differs in execution from the Yellow Warbler 

 it yet retains somewhat of that character, and should form the 

 beginning of the transition to the Chippy type. 



Blackburnian is not a persistent singer, and ma}^ sometimes 

 pass northward in almost silence. He has not been heard 

 singing during the return journe3^ 



This promethean presence gleams from the upper foliage of 

 trees, but delights in the shade trees of parks and lawns fully 

 as much as the wood-land, usually shunning the deeper woods. 

 His is a familiar presence on the Oberlin campus during the 

 early da3\s of May. 



Eastern North America, west to eastern Kansas and Mani- 

 toba, breeding from the northern United States northward to 

 Labrador.
