WARBLER, BLACK-POLL 



The black-poll at first glance suggests the black and 

 white creeper; but instead of a striped head, has a black 

 cap. 



It is said to be one of the most beneficial of warblers, 

 fairly gorging itself on canker worms. 



FLORENCE A. MERRIAM. Birds of Village and Field. 1 



A dainty little fellow, . . . . he is almost hidden by 

 the dense foliage on the trees by the time he returns to 

 us at the very end of spring. ... A faint "screep, 

 screep" like "the noise made by striking two pebbles 

 together/' is often the only indication of the black-poll's 

 presence. 



NELTJE BLANCHAN. Bird Neighbors. 23 



The song of the black-poll is weak, as if he had such 

 a cold as to be almost inaudible. 



PARKHURST. The Birds' Calendar. 31 



It resembles the syllables, tsi-tsi-tsi-tsi-tsi, repeated in 

 a nearly unvarying tone.

WARBLER, BLACK-THROATED BLUE 



For a restful effect in pure white, blue and black, nothing 

 could be finer than the " black-throated blue," as chaste 

 and elegant as one could imagine, and with ample compen- 

 sation for its colder tones in its grace of pose and motion.
