Specimens from Costa Rica, compared with 30,64*7, are smaller; 

 the back more olivaceous ; the median line of the belly whiter ; the 

 crissal feathers longer and more edged with plumbeous ; the bill 

 more tinged with brown. A triangular yellowish spot in the larger 

 coverts apparently indicates a slight immaturity.
