BOMBYCILLA. WAXWING. 



secondaries abruptly rounded, with the shaft prolonged into a 

 narrow oblong coloured horny expansion, Fig. 259. Tail of 

 moderate length, slightly rounded or even, of twelve rather 

 narrow obliquely rounded feathers. 



The Waxwings, so named on account of the alar append- 

 ages, which in colour resemble red sealing wax, belong to the 

 arctic regions of both continents, whence they advance south- 

 ward when the cold becomes severe. In winter, they feed 

 chiefly on berries, but in summer are said to live on insects.
