372 BIRDS OF THE REPUBLIC OF PANAMA PART 4 



Females (3 from Nicaragua) , wing 91.0-97.0 (94.0), tail 99.2-116.0 

 (108.8), culmen from base 23.7-26.0 (24.9), tarsus 26.1-30.4 (28.9) 

 mm. 



Resident. Known in Panama only from the Almirante area of 

 Bocas del Toro, where it has been collected at Almirante, Western 

 River, Fruitdale, and Changuinola River. It ranges north on the Carib- 

 bean slope to Costa Rica and Nicaragua. 



Pedro Galindo collected two nests at Almirante that contained no 

 eggs on May 9 and 11, 1962. Each nest was a woven, pendant basket 

 of long, slender, tough fibers, strongly made but with light showing 

 here and there through the weave. Each had one margin slightly longer, 

 evidently for firm attachment and support in suspension; like other 

 orioles, this species hangs its nests from two adjacent horizontal 

 branches. The outside diameter of the nests was HOx 120 mm by 120 

 mm deep, and the inside diameter was 90x90 mm by 90 mm deep. 

 Skutch (Pac. Coast Avif. no. 31, 1954, p. 265) found a nest of the nomi- 

 nate race in Guatemala that had three eggs on April 30, 1932. They 

 were "white with the faintest tinge of blue, heavily marked on the 

 thicker end with pale chocolate blotches, among which were mingled 

 irregular spots of black. There were a few faint marks of pale brown 

 over the remaining surface. These eggs measured 24.6 by 17.9, 23.4 

 by 17.9, and 23.8 by 17.9 millimeters." The eggs hatched after 14 days 

 of incubation. The young had salmon-pink skin and long gray down 

 on the head, back, shoulders, wings, and flanks; they left the nest when 

 12 and 13 days old.
