AMPELIS CEDEORUM, (Vieill.) Gray. 



Cedar Bird; Carolina Waxwing. 



Not seen at Pembina but found at various other points along the Line, 

 and ascertained to be particularily abundant in the Eocky Mountains. 

 At this locality, two of its conspicuous traits were illustrated, namely, the 

 lateness and the irregularity of its breeding. On the same day, August 

 19, that I took young birds fully fledged and on wing, a nest contain- 

 ing four eggs was found by one of my assistants, Mr. A. B. Chapin. This 

 might be interpreted upon the supposition that two broods are reared 

 in a season, but I do not think that such was the case in the present 

 instance : the bird is too late a breeder for this, at any rate in such a 

 high latitude, not far from its northernmost limit of its distribution.
