Resident. Rare, in heavy forest. Known from a pair taken at the 

 old Tacarcuna village site at 950 meters elevation on the base of Cerro 

 Mali, and a male from 550 meters at Cana, on Cerro Pirre, Darien. 



The male and accompanying female from which this bird was 

 described were collected for Dr. Pedro Galindo, of the Gorgas 

 Memorial Laboratory on July 4, 1963. The locality was the forest 

 surrounding the field camp, at the old Cuna Indian village on the 

 upper Rio Pucro. An earlier specimen, also an adult male, collected 

 March 20, 1912, by E. A. Goldman near Cana, on the lower slopes 

 of Cerro Pirre, was wrongly identified originally as Serpophaga 

 cinerea grisea, and through this was overlooked in earlier studies. 



The bird is listed here in the genus Myiopagis, following treatment 

 by Zimmer (Amer. Mus. Nov., No. 1108, May 14, 1941, p. 20). The 

 much brighter colors of the female, with yellow abdomen and greenish 

 back, are in definite contrast to the grayer color pattern of the male. 

 Both are marked by the prominent white in the crest. 



While the species ranges widely from Colombia and southern 

 Venezuela to Bolivia, northern Argentina, and southern Brazil, little 

 is known of it other than the few records of specimens collected. In 

 these, four geographic races have been described. The bird of Darien, 

 generally similar to M. c. parambac (Hellmayr) found from the 

 Baudo Mountains in Choco, western Colombia, south to western
