here add his brief but interesting description of this district : 
* Machako’s Station, on the Uganda road, is situated at the 
edge of a grassy plain, which stretches for some miles to the 
westward. The only wood in the neighbourhood consists of 
single thorn-trees, scattered about at distances of 200 yards. 
The nearest forest is at Kikuyu, about forty-five miles away. 
On the east side of the station is a valley, at the bottom of 
which is a stream about two feet wide and three inches deep. 
The whole valley is cultivated, and a few patches of rank grass 
grow in the bed of the stream. On its eastern side the 
mountains rise abruptly, and some of them are 2,000 feet 
higher than the station, which is 5,300 feet above the sea- 
level.” 
Dr. Ansorge found the species at Nairobe, and during the 
Makinder Expedition to Mount Kenia it was met with in flocks 
of thirty or forty together, and appeared to be common along 
the western foot of the Mount Settima range. Sir Harry 
Johnston obtained the species at Lake Baringo, which is the 
most northern range yet recorded for these Weaver-birds. 
In the British Museum there are many specimens collected 
by Lord Delamere, comprising males in winter plumage from 
Kikuyu in December, and from Lake Nakuro and Molo River 
in the early part of January, and full plumaged males in 
Likipia, January 21. Also several at Ngari Mosser and 
Elbedjeda on Mount Kenia. Specimens were procured in the 
breeding plumage by the Makinder Expedition, September 26, 
and in the winter plumage by Dr. Hinde at M’Gongo, Octo- 
ber 20. This shows that the spring and autumn moults take 
place about January and October.
