Resident. Found in forested areas; in the Canal Zone through

 Zone east through eastern Province of Panama and Darien. 



Knowledge of the occurrence of this species in Panama began with 

 the work of McLeannan, who sent specimens to Lawrence in New 

 York about 1861. About 2 years later others came to Sclater. and 

 to Salvin, in London. Goldman collected a female near Lion Hill, 

 January 18, 1911, and Hallinan (Auk, 1924, p. 313) secured 1 on 

 the Rio Caimitillo, back of Miraflores Lake, October 20, 1915. In 

 later years it has been found regularly on Barro Colorado Island. 

 On April 4, 1954, at Farfan Beach, Canal Zone, a pair came into 

 the top of a dead tree, and remained peering about for some time. 

 When they flew several yellow-green vireos attacked them violently. 

 On January 9, 1960, I recorded 1 in a guarumo standing in the open 

 in the forest reserve back of Gamboa. 



The first record for eastern Panama is of 1 sent to Salvin by Arce, 

 taken near Chepo in 1864. March 10, 1950, I collected 1 in heavy 

 forest at 300 meters elevation on Cerro Chucanti. And on March 

 27, secured 2 males, and saw another individual in the forest at Charco 

 del Toro on the Rio Maje. 



In Darien, an Indian brought 1 to Thomas Barbour on the Rio 

 Esnape, April 3, 1922. Bond and De Schauensee (Acad. Nat. Sci. 

 Philadelphia, Mem. 6, 1944, p. 31) recorded 1 from Cerro Sapo. 

 On the Rio Jaque, April 4, 1947, I found 1 in early morning resting 

 in the sun in a tall tree top. 



As the bird lives in heavy forest, usually in the tree crown, and has
