 (particularly on the scapulars, which have some spots of ochraceous) , 

 and mottled, vermiculated, and irregularly barred with brownish 

 black, the scapulars more or less solidly black medially, the cervix 

 rather duller and more uniform; tail-feathers fuscous, more or less 

 irregularly and rather broadly barred with buff, cream buff, and 

 whitish, these bars on the upper side of the tail much mottled and 

 broken by fuscous; a much broader pure white subterminal band; 

 wing-quills fuscous, all but the outer primaries more or less spotted
