 metallic grass-green ; six middle tail feathers bronzy purplish black, 

 their outer webs edged with bronze-green, this occupying nearly the

 have a copper-bronze luster in the proper light; three outermost pairs 

 of rectrices black, tipped (for about .25-.30 of an inch) with white, and 

 narrowly barred with white along the edge of the outer web (entirely 

 across near the white terminal spot, and much more distinct, as well as 

 extending much farther toward the base on the outermost feather). 

 Secondaries dull slate-black, margined and irregularly barred with dull
