minutissima, Bp. 
Diagn.—Tail 53 mm. long only, with three to four white spots, not reaching to the 
shafts. 
Descr.—The head-feathers light ash-grey ; each with three round white spots, and 
‘margined with black. Shoulder-coverts partly unicolor, partly with three white or 
rufous-yellow-white spots, mostly on the outer webs, which do not form a large band. 
The smaller feathers of the wings with round white spots on the outer webs, sometimes 
on the shaft and concealed. Outer webs of the first and second wing-feathers unicolor ; 
third and fourth with two to three rufous-yellow spots, The wing on the interior parts 
whitish, towards the end dusky, with five to six dark cross bands. ‘The tail with three 
to four pairs of white spots, not reaching to the shafts. The lower parts white, with 
large rufous spots, and two long stripes along the belly. Tarsi rufous-yellowish-white, 
distinctly spotted with rufous. 
Azara says that this smallest of all the Owls, or Rapaces, attacks with success the 
Turkey and Caracara. All the species of this genus feed on insects, and we cannot 
understand how this pigmy is able to kill birds which surpass him so greatly in 
weight and strength. Azara possibly observed this unusual courage in a captive one, 
and he therefore concluded it exercises the like boldness in a wild state. This, 
although possible, admits of doubt.
