CONSPICUOUSLY BLACK AND WHITE 401 



In twelve days the nestlings were growing quite a 

 respectable coat of brownish gray like that of the female, 

 and could be seen stretching their wings in the saucer- 

 shaped nest so near the edge that they were in imminent 

 danger of falling off. Their call was exactly like that of 

 the young cedar waxwings, a prolonged " pee-eet," sweet 

 and plaintive. The song of the adult is more remark- 

 able for enthusiasm than musical quality, and his call- 

 note is a shrill two-syllabled utterance in the harsh tones 

 of a blue jay. Besides this he has a variety of conversa- 

 tional tones which remind one somewhat of the gentle 

 waxwings. 



In some localities the Phainopepla is called the black 

 mockingbird, but he has not a single characteristic of 

 the mockingbird family, and certainly his vocal powers 

 do not put him in that list.
