Genus CARDELLINA DuBus 



Although in Cardellina the bill is short and titmouse-like in 

 character, the rictal bristles are still fairly well-developed, though less 

 evident than in Wilsonia. 



The wing is rather long, and pointed by the second, third, and 

 fourth primaries, the first (outer) primary about equalling the fourth; 

 the tail is long, the feathers of about the same length ; the feet are dark 

 and slender. 



Cardellina rubrifrons, the only species in this genus, ranges from 

 southern Arizona and New Mexico south to Guatemala. The sexes 

 are virtually alike in color, an exception to the prevailing rule among 

 brightly colored birds.
