 oles" and "Blackbirds.") 



Primaries ; bill with the commissure angulated, as in Fringil- 

 lidce, but usually lengthened, rarely shorter than head, straight or 

 gently curved, without notch or rictal bristles ; culmen usually ex- 

 tending up on the forehead, dividing the frontal feathers. Legs 

 stout, usually adapted for walking. Plumage usually brilliant or 

 lustrous, the predominant color generally black, often with red or 

 yellow ; females usually different, smaller in size, brown or streaky 

 in the lustrous species, and yellowish or dusky in the brightly col- 

 ored ones. Xotes usually sharp, often richly melodious, in other 

 cases harsh. Excepting the "Orioles," the species feed chiefly on 

 seeds. 



Genera about 20, species 100, all American, some of the short- 

 billed forms forming a perfect transition to the Fringillidce ; others
