FAMILY OXYRUNCIDAE 605 



Resident. Rare. Known in Darien from the slopes of Cerro Sapo, 

 back of Garachine ; near Cana, on Cerro Pirre ; and La Laguna and 

 the old Tacarcuna village site, on the north base of Cerro Tacarcuna. 



The first specimens of this race were two collected by E. A. 

 Goldman May 25 and June 11, 1912, on the slopes above Cana 

 on Cerro Pirre. Barbour and Brooks in April 1922 collected the 

 type, a male, and two females near the Rio San Antonio on the 

 slopes of Cerro Sapo, back of Garachine, where the birds came to a 

 feeding tree in the forest. Benson secured a male near Cana in 1928. 



A male, fully grown but in immature plumage (with only a single 

 red feather of the head markings of the adult) was taken by Dr. 

 Pedro Galindo at La Laguna on Cerro Tacarcuna, June 6, 1963. 



In early morning of March 6, 1964, back of our camp at the old 

 Tacarcuna village site on the base of Cerro Tacarcuna, four or five 

 stocky-bodied birds flew down from the forested hill above the 

 river. One alighted in a tall tree where I secured it, a male of this 

 race. In the hand, the bird with its dense feathering, strongly 

 muscled, stocky body, and short legs, in general suggested a cotinga 

 of the larger, heavy-bodied species. In preparing the specimen it 

 was noted that the dorsal feather tract had a broad central apterion. 

 The tract had a winglike expansion on either side near the center 

 of the back, and then narrowed abruptly. In its lower half the line 

 expanded slightly to continue without a break to end at the base of 

 the tail. 



The stomach of the male collected by Goldman near Cana on 

 June 11, 1912, was preserved and in due course examined by me. 

 It was filled with partly digested remains of several spiders, including 

 many tiny eggs, possibly taken with them. In addition there were 

 a few fragments of a large ant, and seeds of small size that I did 

 not identify. The stomach of the one that I collected in the early 

 morning in 1964 was empty. Barbour and Brooks secured their 

 specimens at a feeding tree where they were "in company with several 

 species of Cotingidae." 



As stated under the general heading, the nest and eggs are 

 unknown.
