FAMILY BUCCONIDAE 489 



Resident. Found in the forests of western Bocas del Toro from the 

 lowlands to the lower edge of the Subtropical Zone. 



The first report of this bird from the Republic is by Carriker (Ann. 

 Carnegie Mus., vol. 6, 1910, p. 581), who in his statement of the 

 range in Costa Rica mentioned "the Caribbean slope of . . . northern 

 Chiriqui," and among the localities for his specimens included 

 "Cuabre." His camp there according to information that he gave me 

 was on the Costa Rican bank of the Rio Sixaola in the center of the 

 big bend in the river about 4 kilometers southeast of the place marked 

 Margarita on modern maps. The most eastern record in Panama is of 

 male and female taken by Kennard, March 9 and 23, 1926, near 750 

 meters on the Boquete trail back of Chiriqui Grande. Two in the 

 Havemeyer collection at Yale were taken the following year by Austin 

 P. Smith at Sibube on the Rio Sixaola on February 12, and at Zegla, 

 on the lower Rio Terebe, a tributary of the Rio Changuinola, on 

 May 16. A male in the U.S. National Museum came from the Gorgas 

 Memorial Laboratory collected by Rudolfo Hinds, September 20, 

 1961, at about 750 meters on the Rio Changuena, on the headwaters of 

 the Changuinola. 



This race ranges north on the Caribbean slope to southeastern 

 Honduras.
