92 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



party under the leadership of Harold Anthony, in the upper Tuira 

 Valley at Tapalisa, Cituro, and the old Tacarcuna village site at the 

 base of Cerro Tacarcuna. Barbour and Brooks took one on the Rio 

 Esnape, Darien, April 3, 1922. Griscom received several from eastern 

 San Bias, taken by Wedel near Ranchon and Puerto Obaldia. 



In my own studies I found the Rufous-rumped Leaf -gleaner first at 

 600 meters on Cerro Azul March 31, 1949. On Cerre Pirre in late 

 January and early February 1961, it was common at 460 meters in the 

 upper valley of the Rio Seteganti, and on March 6, 1964, I took one 

 at 575 meters on the Rio Tacarcuna. 



These are birds of the heavy forests where they range rather low, 

 climbing actively over branches, particularly those that are broken 

 and dead, to search among the epiphytes. While their method of 

 climbing may suggest that of a woodpecker, they are quicker and 

 more active in much of their movement. To the eyes of a naturalist 

 trained in the north they seemed completely strange, unlike any 

 northern species. 



The stomachs of three from Cana, preserved by Goldman, I found 

 crammed with a variety of small insects, and a few remains of spiders 

 and their eggs. The insects taken included roaches, and their eggs, 

 bits of a wasp, a pentatomid, a caterpillar skin, and numerous beetles 

 of a variety of species.
