CERRO AZUL NUN BIRD 



on remainder of the body. Wing quills and tail 

 glossy bluish black. Bill bright red. 



Recorded from Cerro Azul, Canal Zone, by 

 Ridgway. The nun birds are forest birds of re- 

 tiring habits, that are still too poorly repre- 

 sented in collections to satisfactorily determine 

 the number and the distinguishing characters 

 of the species composing the genus. They are 

 rare in the Canal Zone and the two species 

 credited to it are of doubtful validity and may 

 not be distinct from each other.
