(La Merced, Chanchama3'o ; Kalinowski leg.) b}' its much smaller size, shorter as 

 well as deeper bill, and by having the sides slightly more brownish grey, less

 the dull brownish grey (instead of deep buff or ochraceous buff) sides and flanks, 

 white (not deep buff) under tail-coverts, more olive-grey (less greenish) upper 

 parts, etc. 



Additional material is required to establish the status of the Madeira form.
