and he believes it may be declining. This race ranges into southwestern 

 Costa Rica. 



Although Paynter (Bull. Mus. Comp. Zool. 148, 1978, p. 350) could 

 "find no specific record" for Panama, Davidson (Proc. California 

 Acad. Sci. ser 4, vol. 23 no 17, 1938, p. 261) reported 2 specimens taken 

 near Concepcion, Chiriqui, in 1929, and there are 2 specimens in the 

 American Museum of Natural History and 6 in the Smithsonian col- 

 lections taken from 1903 to 1960. 



Skutch (Pac. Coast Avif. no. 31, 1954, pp. 89-94) has studied the 

 nesting of this race in Costa Rica, where the breeding season may run 

 from February through September. The nest is usually placed in a 

 bush or tangle of vines in a thicket; most are from 2 to 4 m from the 

 ground. Both sexes may build the nest together, or either male or fe- 

 male may build it alone. It is a bulky open cup with a foundation of 

 coarse dry weed stems or pieces of vine, body of large dead leaves, and 

 a lining of fine rootlets, fungal filaments, and rachides of acacia leaves. 

 One measured 15 cm in diameter by 7.5 cm in height, with an interior 

 7.5 in diameter by 3 to 4 cm deep. Twenty-one nests found by Skutch 

 contained either two eggs or 2 nestlings. The eggs are slightly glossy 

 pure white or faintly tinged with blue. The average measurements of 

 twenty eggs were 25.5 X 18.5 mm. Incubation is carried out by the fe- 

 male alone and requires 15 days. Both parents feed the young, which 

 remain in the nest about 12 days.
