HALF-COLLARED ANTWREN 



FIG. 85. Polioptila s. superciliaris 



(Nat. Size) 



Female. Similar to male but with less black 

 on head and the gray of upper parts duller. 



Jewel says it is found in the second growth. 

 Its very small size, slender build and com- 

 paratively long tail enable it to be easily recog- 

 nized among the other small birds of the region. 

 It is active and nervous in its movements, 

 climbing around after the manner of a warbler, 

 in tree tops as well as in undergrowth. 



2. Microbates cinereiventris semitorquatus 



(Lawrence) 

 Half-collared Antwren 



Sexes alike. Length 98 mm. (3.80 in.); 

 tail 27 mm. (i.io in.). Dark brown above, 

 the sides of the head tawny buff, this color 

 extending to sides of neck, the front of the 

 cheeks white; chin and throat white bordered 

 on each side by a broken streak of black, the 

 remaining under parts gray, passing to olive 

 on flanks, the upper chest broadly streaked 

 with black.
