60 EINAR LÖNNBERG, BIRDS. 



Bubo maculosus cinerascens Guér. 



Rchw. I, p. 656. 



A female specimen with the length of wing only 302 mm was flushed from a rocky 

 ledge with overhanging bushes in a dry river-bed in the thornbush-country north of Guaso 

 Nyiri, below Chanler Falls, and shot. Its small size, although a female, may prove that 

 it belongs to the northern race as also could be expected at this locality. This was the 

 only specimen seen, so I suppose it is not very common. 



Asio leucotis (T em.). 



Rchw. I, p. 661 & III, p. 821. 



One day ( 12 /a) when walking through the thornbush north of Guaso Nyiri and 

 below Chanler Falls I saw a pair of this Owl in a rather small bush, hardly more than two 

 meter high and not very wide. They sat so close together that both were secured with 

 the same shot of the small specimen gun. That was the only time I saw any owls of this 

 kind. 



Iris yellowish red, 13,5 mm. Length of wing 183 mm in the male, 185 mm in the 

 female. The female of this pair is darker, -has broader black longitudinal streaks on the 

 back, and the black on the head much more broadly developed than in the male. The for- 

 mer is evidently representing C. von Erlanger's P. I. nigrovertex as figured by him in 

 Journ. f. Ornith. Jahrg. 1904 Taf. XIX, fig. 1, while the male of the same pair is similar to 

 a normal A. leucotis. I must therefore regard »A. 1. nigrovertex» only as a melanistic 

 phase or individual aberration. 



Syrnium woodfordi (A. Sm.). 



Rchw. I, p. 668. 



In the dense forest on the eastern side of Kenia this owl is probably not uncommon. 

 I saw and shot the two specimens which I was allowed by personal complimentary license 

 to shoot. A specimen obtained 27 /i is very dark in some parts, but although there are 

 several varieties named I do not think that these small differences in colour are of any 

 subspecific importance considering, how the species of Syrnium vary in colour individu- 

 ally. A specimen shot 18 /a was moulting the tail. 



Glaucidium perlatum (Vieill.). 



Rchw. I, p. 674. 



One evening, 8 /s, when returning to the camp at Guaso Nyiri below Chanler Falls 

 I saw a specimen of this species feeding on a small bird (Bradornis) and shot it. It had 

 unspotted head and was thus of the kilimensis-type. The other member of the pair was 

 also present, and had the head unspotted. About a week låter I saw another specimen
