■ Specimens from Ceara in the reddish plumage are paler (especially on the 

 tail) than those I have seen from other localities. 



'' Glaucidium brasilianum medianum Todd: The brown phase differs from G. b. 

 ridgwayi (Sharpe), having the upper parts much browner (less grayish) and streaks 

 on under parts more ruf ascent; differs from G. b. phalaenoides (Daudin) in its paler, 

 more buffy brown upper parts and less heavily streaked under parts; tail more 

 decidedly and regularly barred.
