Zoological E.xplorations. 273 



trees bordering a slough, where they seemed to have excel- 

 lent hunting. They perched on the lowest branches and 

 bushes, and evidently lived on the insects flying over the 

 water. None secured at Grand Rapids, where it is replaced 

 by E. minhmis. 



Seven specimens secured. 



Family corvid.x:. Crows, Jays, etc. 



Cyanocitta cristata (Linn.). Bine yc^y. I saw, in 

 the Post Residence near Chemawawin, a mounted specimen 

 of this species, which was killed bv the Indians and mounted 

 bv Mrs. King, the wife of the Post Master. 



Perisoreus canadensis. (Linn.). Canada yay. ^^ Whis- 

 key JackP x\bundant at Grand Rapids. The white on fore- 

 head and head is much more restricted than in Colorado 

 specimens, although this may be due to immature or summer 

 plumage. In the series of ten specimens of various ages, 

 which we secured, the change from the uniform dusky young 

 to the adult plumage seems to progress as follows : 



The first white to appear is on the tips of the rectrices and 

 primaries and the malar stripe; next a white band appears on 

 the breast, and the malar stripe is continued into an Hi-defined 

 light patch on sides of neck; the neck band broadens and 

 extends around the neck, and forward on throat and chin; the 

 white on forehead appears and gradually extends backward. 

 The average measurements of the specimens secured are: 

 Length 10.9, wing 5.5, tail 6.'^^ tarsus 1.2. The Indians 

 accuse this bird of warning the moose of the approach of the 

 hunter. 



Breeds within the Arctic Circle. (MacFarlane). 



CoRVus CORAX siNUATUS (Wagl.). American Raven. 

 The call of the raven was heard by Messrs. Smith and RusseU, 

 and we were told by Mr. McLean that a species of raven was 

 not uncommon at Grand Rapids.
