1979, p. 27) refer to two active nests on Barro Colorado Island in Feb- 

 ruary. Major General G. Ralph Meyer flushed a bird from its nest near 

 the Naval Station on Gamboa Road in the Canal Zone on May 15, 1941. 

 The nest was of dried grass woven somewhat like that of an Orchard 

 Oriole (/. spurius) though not so neatly or precisely made. Some of the 

 strands of grass still had a greenish tinge. Although it was possible to 

 see through any part of the nest, it had a firm wiry feeling and was 

 noticeably resistant to crushing. It was placed about 7 m above the 

 ground, being suspended at three points in a fork of a tree that was 

 about 10 cm in diameter at the base. The outer diameter of the nest was 

 11 cm, the inner diameter 10 cm; the outer depth was 9 to 13 cm and 

 the inside 6 to 9 cm. The three eggs were whitish, marked with pale 

 purplish brown blotches primarily at the wider end of the egg and with 

 a few dark brown scrawls scattered irregularly over the surface. They 

 measured 24.8x17.2, 25.0x17.0, and 25.6x17.5 mm.
