tion in the Peabody Museum at Yale), and specimens from 600 

 meters elevation near Cana, Darien. The species has been reported 

 most often in the western part of the republic. 



On Isla Coiba on January 17, 1956, a female, attracted by the calls 

 of a wounded thrush, came dashing in through low branches to a 

 perch a few feet from me. This bird had the double ovary, usual in 

 the genus Accipiter, with indication in the left lobe that the bird had 

 laid rather recently. The right ovary was about one-third the size 

 of the other. A few days later, on January 23 a prisoner brought me 

 an immature male that had begun the molt to adult dress on back, 

 tertials and tail. 



Capt. Vivian Hewitt (Ool. Rec, 1937, pp. 13-14) reports an egg 

 collected in the "Rio Orinoco District" in Venezuela, as white with 

 slight rust-colored streaks. It measured 38.0x32.7 mm. The nest, 

 on which the bird was seen, was small and cup-shaped, built of 

 sticks and lined with a few leaves, placed near the end of a branch 

 about 15 meters from the ground. Schonwetter (Handb. Ool., pt. 3, 

 1961, pp. 143, 160) records a single tgg from western Ecuador as 

 pale bluish gray, sparingly spotted with dark brown. The measure- 

 ment is given as 46.5x35.2 mm. (As this tgg, in the Passler collec- 

 tion, is so different from the one reported by Hewitt it is possible that 

 it is wrongly identified.)
