86 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



streak black, spotted with dull white ; foreneck, side of neck and 

 center of breast cinnamon, with very narrow shaft lines of huffy 

 white ; sides, flanks, and abdomen warm brown ; under tail coverts 

 cinnamon-brown ; under wing coverts bright cinnamon, but wing 

 edgings on under surface as in adult. The bill is definitely shorter 

 than in the mature bird. 



This is a species of mountain forests, found in Costa Rica and 

 western Panama, in Darien, and in the Andes from Colombia, south 

 to Ecuador and Peru, including the mountain areas of western 

 Venezuela. 



Two distinct races are recognized in Panama, one in Chiriqui, the 

 other in Darien. 



SYNDACTYLA SUBALARIS LINEATA (Lawrence) 



Anabazenops lincatus Lawrence, Ann. Lye. Nat. Hist. New York, vol. 8, 1865, 

 p. 127. (Angostura, Costa Rica.) 



Characters. — Lighter, brighter brown above ; decidedly lighter, 

 more greenish brown on under surface ; chin and upper throat darker 

 buff ; larger. 



A male in the British Museum, taken by C. H. Lankester at Cachi, 

 Costa Rica, May 8, 1912, has the following data on the label: "iris 

 brown, bill black, ochraceous on gonys, feet yellowish olive." 



Measurements. — Males (10 from western Chiriqui), wing 90.0- 

 94.6 (92.4), tail 80.0-92.5 (85.5), culmen from base 20.7-22.0 

 (21.3), tarsus 22.2-23.8 (22.9) mm. 



Females (10 from western Chiriqui), wing 83.7-89.0 (86.9), tail 

 77.0-83.0 (80.3), culmen from base 20.6-22.3 (21.2), tarsus 21.8- 

 23.1 (22.6) mm. 



Resident. Fairly common in Subtropical Zone forests on the Pacific 

 slope, in western Chiriqui from 1580 to 2130 meters, and in Veraguas 

 (Santa Fe, Chitra) ; recorded also from Calovevora on the Caribbean 

 side in northern Veraguas. 



They are found singly or in pairs, at times with the scattered 

 flocks of small forest birds that feed in company. With active move- 

 ment they range from the undergrowth to the high tree crown, climb- 

 ing alertly over vines and along the tree limbs, moving quickly to 

 cling to the sides or undersurface of twigs and larger branches. In 

 the course of such activities they may hang briefly, braced with tail 

 pressed against the branch, while they pull out dead leaves lodged 

 among epiphytes, in search of the insects that form their food. Less 

 frequently I have found them in small clearings in the forest, feeding
