These birds are quite common and breed throughout their 

 summer range. They frequent the groves and woods skirting 

 streams and swampy lands. A rather noisy bird, that at short 

 intervals utters its loud call note, "Ke-wick." Its ordinary 

 note is a sharp "Pip," and, as it flits about from bush to bush, 

 often repeats the same in a twittering manner. Their food hab- 

 its and actions are essentially the same as those of the Acadian; 

 but their nests are constructed in a very different manner, the 

 same being placed in the upright forks of a bush or sapling,
