Rufescent phased 



Adults (sexes alike) . — Similar in pattern of coloration to the grayish 

 brown phase, but general color of upper parts much browner (bister 

 or deep snuff brown to verona brown) with the spotting (especially 



a TMs rufescent phase seems to occur mainly if not exclusively in the extreme 

 southern and eastern parts of the range; at least the only examples I have seen are 

 those from Michoacan and one each from Galindo, Tamaulipas, and an unknown 

 locality in Nuevo Leon, there being also grayish brown specimens from the last two 

 but none from the first. The only specimen seen from the State of Morelos is in the 

 grayish brown plumage.
