Measurements. — Males (10 from Chiriqui and Costa Rica), wing 

 100.1-107.6 (103.1). tail 58.2-62.9 (60.2), culmen from base 14.0- 

 15.9 (14.9), tarsus 20.0-21.7 (20.6) mm. 



Females (4 from Chiriqui and Costa Rica), wing 102.7-106.3

 tarsus 20.8-22.2 (21.4) mm. 



Resident. Rather rare in high forest in the upper Tropical and 

 lower Subtropical Zones in western Chiriqui. 



This interesting species was reported for the Republic first by 

 Salvin (Proc. Zool. Soc. London, 1870, p. 200) from an immature 

 specimen taken by Arce in Chiriqui in 1870, without indication 

 of definite locality. It was listed with a query as the related species 

 Cotinga amabilis, with doubt expressed as to its identity. Salvin and 

 Godman later (Biol. Centr.-Amer., Aves, vol. 2, 1891, p. 139) identi- 

 fied it definitely as C. ridgwayi, and recorded the locality as Bugaba. 

 In July 1901, W. W. Brown, Jr., who collected two males at Bugaba, 

 reported it as rare and local, "seldom taken by the feather hunters." 



In recent field work near El Volcan around the lakes and the base 

 of Cerro Pando, we have found it with fair regularity but in small 

 number. It ranges also in the hills at Santa Clara toward the Costa 

 Rican boundary. 



In early morning single individuals may rest in the tops of tall 

 dead trees, sometimes at the border of clearings, occasionally in trees 

 standing in forest. In such locations they may shift about among the 

 branches, but aside from this rest quietly. Others have come to 

 guarumos (Cecropia), or to trees with ripening berries, feeding there
