Resident. Not common ; found locally on the Caribbean slope from 

 northern Code east to the northern Canal Zone, and above Madden 

 Lake on the lower Rio Pequeni ; crossing to the Pacific slope on the 

 headwaters of the Rio Pacora in the Cerro Azul. 



The first specimens from which this interesting bird was described 

 were collected about 1860 on the Atlantic slope of the Canal Zone 

 by James McLeannan. The following year McLeannan and Galbraith 

 secured others, 1 male, and 2 females. Lawrence loaned a pair to 

 P. L. Sclater in London, who had them painted for publication, with 

 a note on the plumages of the two sexes (Ibis, 1862, p. 1, pi. 1). 

 In addition to these early specimens there is a male in the National 

 Museum received from Thomas Rhodes marked "near Panama City." 

 A letter from Rhodes in the accession papers dated February 20, 1866, 

 states that he collected with his brother near Panama City in December 

 1865, and that they also bought other birds of "Mr. McClellan of 

 Lion Hill." This certainly refers to McLeannan, the station master 

 at Lion Hill, who had forwarded the earlier specimens mentioned. 

 The Rhodes skin bears a small, paper tag with "No. 37, F." written on 

 it in McLeannan's script so that the bird must have been taken on 

 the Atlantic slope where that collector worked, rather than "near 

 Panama City" as stated on the label. W. W. Brown, Jr., secured 2 

 males at Lion Hill in March, 1900 (Bangs, Proc. New England 

 Zool. Club, vol. 2, 1900, p. 18). Jewel secured a male at Mt. Hope 

 in the Canal Zone, a short distance south of Colon, on February 22, 

 1913 (Stone, Proc. Acad. Nat. Sci. Philadelphia, vol. 70, 1918, p. 

 258). Mrs B. B. Sturges (Field Book Birds Pan. Can. Zone, 1928, 

 p. 215) listed a sight record on Barro Colorado Island. 



In my own studies we found this race first on Cerro Azul, April 

 23, 1949, when a male was taken at the Quebrada Carriaso in the 

 upper drainage of the Rio Pacora. We recorded it next at El Uracillo 

 in northern Code on the headwaters of the Rio Indio, where 1 was 

 taken February 27, 1952, and a pair on the following day, as they
