it is probable that the adult stage is assumed in the spring 
following the winter in which they are hatched. 
The Greater Double-collared Sun-bird was found in the 
Knysna district, Zululand, the Eastern and North-Eastern 
Transvaal, and was particularly plentiful in the two former 
localities. It is found both in the forests and on the open 
hill-sides, and feeds principally on the nectar of flowering 
plants and shrubs, especially Proteas and certain Aloes, in 
common with most of the other Sun-birds, varying its diet 
with small flies and insects, which also are taken from the 
flowers. The flight is swift, and it will often hover to extract 
the nectar from flowers. It is generally seen in pairs, though 
often solitary ; the call is sharp and short, the males some¬ 
times uttering a rather sweet warbling song from a twig or 
the top of a bush. Except for its size, which is not always 
striking, it cannot be distinguished from the two following 
species. 
The soft parts are:—Irides dark hazel ; bill, legs and 
toes black.]

[The sequence of plumage in this species appears to follow 
closely that of C. afer. The Lesser Double-collared Sun-bird 
was noted only in Namaqualand and the Cape Peninsula, 
in both of which localities it is very plentiful ; it was less 
common in the Knysna district. In these localities it feeds 
principally on the nectar of Proteas where they occur, 
flowering heather, and climbing plants, and is commonly seen 
around habitations taking nectar from the cultivated plants^ 
growing in the gardens and on the walls and porches; it is 
so tame and fearless that it has often been known to nest 
in the latter situations. In appearance and call it resembles.. 
C. subalaris. 
The soft parts are :—Irides dark hazel ; bill, legs and, 
toes black.]
