Similar in general coloration to M. mexicanus and M. cinera- 

 scens, but differing from both in the pattern of the tail-feathers, 

 the inner webs of all the rectrices (except the intermediae) being 

 either wholly rufous or eise with a very narrow stripe of dusky 

 next to the shaft of the outer feather. Adult: Above brownish 

 gray (exactly as in M. einer ascens), occasionally tinged with olive, 

 the pileum much browner and with darker shaft-streaks ; wings 

 and middle pair of rectrices dusky brownish, the latter uniform; 

 last row of lesser coverts, middle, and greater coverts, distinctly 

 tipped with light brownish gray; tertials edged exteriorly with 

 grayish white (tinged with sulphur-yellow in fresh plumage) the 

 primaries edged with light rufous toward the base. Outer webs 

 of rectrices dusky brownish (like both webs of the intermediae), 

 the outer pair with the exterior edge much paler (nearly white in 

 some specimens); inner webs of all the rectrices excepting the 

 middle pair clear rufous, including the extreme tip, and usually 

 extending quite to the shaft, though in some examples separated 

 from the shaft by a very narrow streak of dusky. Chin, throat,
