Costa Rica to Venezuela (Caracas, Merida, etc.), western Ecuador 

 dor (Mebli) and central Peru (Vina, etc.). 



The overlapping of the ranges of typical A. p. columliianvs and J[.j9. 

 croceus being quite extensive (Costa fiica to Colombia), intermediates 

 are quite numerous. Such specimens have much less white on the 

 rectrices than A. p. croceus (sometimes merelj" a trace), while in some 

 it is asymmetrically developed, one side of the tail being as in tj'^pical 

 A. 2>- croceus, the other side as in A. p. columhianus. 



' Ten specimens. ^ Eight specimens.
