Inhabits the Temperate Zone of all three ranges. A satisfactory study 

 of oiu" thirty-six specimens is prevented by the fact that only one of them 

 is from the Bogota region, the type-locality. This specimen, taken for us 

 by a native collector on May 12, 1913, at Palo Hueco, Cundinamarca, near 

 Bogota, cannot be matched by any of our thirty-four specimens from the 

 western and central ranges. From more western specimens of the same 

 season it differs in being more olivaceous above, and should the difPerences 

 exhibited prove constant, the birds of the Central and Western Andes may 

 be separated and with them may probably be placed birds from Ecuador, 

 since a single specimen from Pichincha, while darker, is obviously nearer 

 to west Colombian specimens than to the Bogota bird. 



Comparison of this fresh Bogota skin with three old 'Bogota' birds 

 shows a surprising difference in color since the old birds are much ruddier 

 above, the back being snuff -brown, while that of the recently collected skin 

 is olive buffy-brown.

This species appears to be found chiefly in the upper part of the Sub- 

 tropical Zone, since we have failed to secure it at such localities as San 

 Antonio and Miraflores, where our work has been more or less thorough. 

 I can detect no racial differences in our series of fifteen specimens from the 

 three ranges, but comparison of new with old skins from the Bogota region 

 shows striking differences in color, the old birds being fuscous, the fresh 

 ones slate-black above, and on the breast, while the abdomen in old birds 

 is russet, in fresh ones, it is deep chestnut.
