Resident. Found rarely on the Pacific slope from the lower Rio 

 Bayano, eastern Province of Panama, eastward to Darien ; recorded 

 on the Caribbean side on the Rio Pequeni, back of Madden Lake, 

 and in older accounts from the northern Canal Zone. 



The first report for Panama was by Lawrence (Ann. Lye. Nat. 

 Hist. New York, vol. 7, 1862, p. 473) who received male and female 

 collected by McLeannan. The locality was not stated, but it is as- 

 sumed that they were from the Atlantic side of the Canal Zone, as 

 this was the main area of work by this collector. On March 4, 1961, 

 on the Rio Pequeni, near the Candelaria Hydrographic Station, I 

 collected an adult male in breeding condition from a tree that pro- 

 jected over the river. The bird moved slowly in short flights through 

 the branches. These are the only records known to me for the 

 Caribbean side. From the Pacific slope, there are two males and four 

 females in the Peabody Museum at Yale, taken by Austin Smith near 

 Puerto San Antonio on the lower Rio Bayano, in February and 

 March 1927. 



Near Charco del Toro, at the head of tidewater on the Rio Maje, 

 on March 20, 1950, I collected a female from two that moved quietly 

 in the middle branches of a tree beside the river. In Darien, at the 

 mouth of the Rio Paya, on February 24, 1959, I secured a male as it 

 rested in a guarumo adjacent to a clearing, and on March 7, took 

 another from a tree overhanging a playon on the Rio Tuira. Near 

 the Indian village of Pucro in this same region I secured a male, 

 feeding in the top of a guarumo on the river bank, January 30, 1964, 

 a female from a group of small birds at a feeding tree, February 1, 

 and another female, on the following day, as it rested in a tree top in
