I04 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



one salamander, one frog, one beetle, and other items not clearly 

 recognized. 



This species ranges regularly in the undergrowth in heavy forest 

 where it searches along branches and examines carefully dead leaves 

 and other accumulations in moss and airplants in search of food. 

 The birds are found singly or, in the breeding season, in pairs. One 

 of their notes is a rattling call like that of some of the woodpeckers. 

 Other notes are short and more explosive in sound.

Xenops rutilans Temminck, Nouv. Rec. Planch. Col. Ois. livr. 12, 1821, pi. 72, 

 fig. 2. (Brazil.) 



A small, brown, climbing bird, with the under surface and crown 

 streaked prominently with white ; an elongated white patch on the 

 side of the head below and behind the eye. 



Description. — Length 120-130 mm. Bill sharply pointed, with the 

 line of the culmen straight, mandible strongly recurved, but also 

 sharply pointed. Adult (sexes alike), crown and hindneck blackish 

 brown, streaked narrowly, but definitely, with dull buff; back and 

 scapulars dull cinnamon-brown, the back streaked with cinnamon- 

 buff ; rump, upper tail coverts, and tail cinnamon-rufous, the latter 

 with the inner webs of the second to fourth rectrices largely black; 

 wing coverts in general like back, but with more or less concealed 

 basal portions dull black; secondaries and primaries dull black, with 

 an extensive central area and external edgings of cinnamon-buff; 

 superciliary line white to huffy white ; lores gray ; postocular streak 

 brownish black ; auricular region dusky streaked with white to grayish 

 white and dull buff, with a broad pure white stripe below (of slightly 

 elongated feathers); chin and throat white; rest of under surface 

 light grayish brown, with a ruf escent wash on the abdomen ; under 

 tail coverts cinnamon ; under surface striped with white, the stripes 

 broader on the breast ; axillars white ; under wing coverts white to 

 cinnamon-buff ; cinnamon-buff markings on middle of wing showing 

 broadly on lower surface. 



The streaked breast identifies this species from the other Xenops 

 found in the Republic. It ranges from Costa Rica and Panama 

 across northern South America to Trinidad, and south to Bolivia, 

 northwestern Argentina, and Brazil. Two subspecies are recognized 

 in Panama.
