 pale with dusky tips. 



Length about 7-0; wing 4-10; tail 2-75; tarsus O95; culmen 

 0-55. 



The female resembles the male in size and coloration. The 

 young bird has no white spots on the head and back ; the white 

 nuchal collar is without the rufous edging, and the white on the 

 thighs and throat is washed with rufous. 



Distribution. The Pearl- spotted Owl is found over Africa south

 forests of west Africa. 



Within our limits it does not seem to be found south of the 

 Orange river or in Natal proper, but north of this is everywhere 

 abundant up to the Zambesi.
