BLACKBURNIAN WARBLER. 369 



season is over. In the fall these birds are again seen in increased 

 numbers, many being in the young plumage, and not in such haste to 

 depart, although none remain over the winter. 



The musical powers, if they have any, are not exercised in this 

 latitude, the birds while here being mostly silent. They feed largely 

 on winged insects, which are never plentiful till the end of May, and 

 this may account for the Black-polls being late in arriving in spring. 



Viewed from the ordinary traveller's standpoint, one would expect 

 that the birds which go farthest north would be the first to start on 

 the journey, but such is not the case. This species, which is the very 

 latest to arrive from the south, keeps moving on the northern route, 

 passing many which left the winter rendezvous before them, and 

 though some may drop off by the way, large numbers keep on till 

 they reach Alaska, and they are found even in Greenland. 



Macfarlane noticed this species breeding on the Anderson River, 

 and its eggs were taken at Fort Yukon on the 8th and 10th of June.
