The sacred Ibis was very common on the shores of Lake 

 Naiwasha. In flocks of 10 to 20 in number I often saw them 

 walking in the short, dry grass on the acacia plains (in the 

 month of April) or, together with Buhulcus, following the cattle. 

 They were very shy in these parts and I did not succeed in 

 getting within range. 



At the Gulf of Kavirondo in Victoria Nyauza, where they 

 were also numerous, they frequented the plains and here I had 

 an occasion to shoot 3 young birds and 1 adult. 



During the hottest hours of the days they are mostly found 

 on the shores or on the sand-banks in or near the water, but 

 in the mornings and evenings they take to the grass-plains or 

 cultivated fields to look for food. 



The full-grown male has a wing-measurement amounting to 

 385 mm, tarsus 110 mm, culmen 170 mm and is in full dress. 

 The outer-web and tips of a number of the large, outer wing- 

 coverts and the feathers of the flanks are light ochre-yellow. 



One of the cf juvenile birds, which has almost the com- 

 plete adult dress, with secondaries and primaries of a steel-blue 

 and green glossy colour, the latter beginning to get abraded and 

 defused, still has the neck completely covered with small feathers. 

 On the throat these are quite white and worn at the edges, so 

 that often only the shaft and small fragments of the web are left. 

 The head, sides of the head and cheeks are thickly covered with 

 longer, unabraded black feathers, which become thinner towards 

 the back parts of the neck. Both on the head and the neck 

 there are numerous white feathers sprinkled among the black ones. 



In the two somewhat younger birds the feathers of the crown 

 and back of the neck are not black but dark-brown and on 

 account of their age, larger and whole. 



Irides dark-brown; bill and legs black. ^

In the Gulf of Kavirondo this race was rather common, 

 frequenting the trees fringing the shores.
