124 ORNAMENTAL WATERFOWL. 
In the beautiful “‘ Catalogue of the Knowsley Menagerie,” 
date 1846, we find the following notes by Lord Derby :— 
‘* These birds breed freely at Knowsley. On the approach of a 
stranger they have the habit of raising their bodies nearly erect, swelling 
out their breasts, and flapping their wings against the legs of the intruder. 
They sometimes bend themselves backward to such an extent that they 
appear as if they would fall on their backs.” 
Nattera obtained eight specimens in one day in Guiana, 
and found grains and seeds in the stomach. 
Mr. Blaauw has kindly given me the following particulars, 
and writes :— 
“T have also repeatedly bred Orinoco Geese ( Chenalopex jubatus ), 
and have kept the species since 1887. 
“These beautiful birds, which are interesting not only from their 
splendid plumage, but also by their curious antics, are not hardy; that is 
they cannot stand frost. If kept inside in frosty weather they do extremely 
well, and live for many years in captivity. Besides grain and green food 
they want a good supply of animal food (worms or meat chopped finely), and 
I have found that without this animal food the eggs are not fertilised. 
“The general colour is a buffish-white. A blackish-brown band 
runs from the bill to the end of the tail, there is a round spot of the same 
colour over the ears, transverse band over the wings, and one more 
backward. Between the blackish and the white parts there is a rufous edge. 
The bill and legs are black. 
“The young birds are very active and easy to rear. They feed 
principally on duck-weed, bread crumbs, and ants’ eggs, and gradually take 
grain when they get older. The first plumage is a weak washed-out copy 
of the dress of the adults. Very soon after they are full grown, they begin 
to moult, and before the winter they have assumed adult plumage. At that 
time the legs have also acquired the red colour, but the red is not so intense 
as in old birds.”
