fed chiefly on the seeds of the Norway spruces which bore an 
abundant crop of ripe cones. The hemlocks also fruited heavi- 
ly and the Crossbills were seen eating their seeds on several 
occasions . 
I learned nothing new about the habits of these Cross- 
bills. Indeed their restless and erratic movements made it 
practically impossible to study them at all closely. As far 
as I was able to ascertain they were never accompanied by Red 
Crossbills nor did they appear to associate with any other 
species of birds. I heard them utter only the regulation 
flight notes but Mr. Glover Allen tells me that during the past 
summer (in August, I think it was) when he found them very

Wellesley, Cambridge and vicinity, Mass. 
1899. On the afternoon of the 25th I found 5 of these Cross- 
Nov. 1-38. bills feeding on the seeds of a Norway spruce in the Wellesley 
College grounds. One bird was a rosy-red male; all the others 
being either females or young males in yellowish green plumage.
