the Birds of Ngamiland. 401 



there is a second and very similar example from Damaraland, 

 procnred by C. J. Anderssou ; both these birds no doubt 

 represent extreme examples of the grey phase, while the bird 

 from N. Uganda, described by Neumann as Pisorhina capensis 

 tigand(B, is typical of the red phase. 



This was the only specimen of the Cape Scops-Owl met 

 with during the journey. It was found among dry acacia- 

 forest in the Kalahari, and was quite invisible except when 

 moving. 



Glaucidium capense (Smith). 



Glaucidium capense Stark & Sclater, iii. p. 259 ; Reich, i. 

 p. 672. 



a. c?. Mababe Flats, 3000 ft., 8th August. (No. 81, 

 R. B. W.) 



Iris yellow ; bill light horn-coloured ; feet light brown. 



A few of these Owls were seen in Ngamiland, but they are 

 very shy and difficult to obtain. I have never been able to 

 identify the note of either this species or of Scops capensis. 



Strix flammea Linn. 



Strix flammea maculata Reich, i. p. Q7Q. 



St7ix flammea Stark & Sclater, iii. p. 237. 



a. S- Lake Ngami, 2700 ft., 11th July. (No. 59, 

 R. B. W.) 



Iris dark brown ; bill white ; feet brown. 



I believe the Barn-OAvl in South Africa breeds almost 

 entirely in the nests of the '' Hammer-Kop ^' {Scopus 

 umbretta), and that these unhappy birds have to supply 

 every pair of Barn-Owls in the district with a house before 

 they can breed themselves. 



ASTUR POLYZONOIDES (Smith). 



Astur polyzonoides Stark & Sclater, iii. p. 358 ; Reich, i. 

 p. 556. 



a. $. Molopo River, 3000 ft., 8th April. (No. 1, 

 R. B. W.) 



Iris scarlet ; bill black, base yellow ; feet yellow.
