 paler gray (often nearly white), and tail without a distinct subapical 

 band of darker, usually without trace of any darker band.

 drab to light purple-drab, passing on hinder crown, occiput, and nape

 drab or vinaceous-drab, the hindneck glossed with metallic purple, 

 violet, or greenish; back and scapulars similar in color to hindneck
