made a point of examining these nests, and frequently with success; the
occupants, like the Bower Bird of Australia, embellishing their dwellings
with any glittering or bright-coloured thing they can pick up. In the
karroo between Worcester and Robertson I saw a nest placed on the ground
on the side of a trifling rise; it was at least three yards in length,
by one and a half across, with a small entrance-hole at one end." From
Jules Verreaux we learn that these remarkable structures contain three
distinct chambers, the partitions of which are carefully formed, like
the outer walls, of twigs and clay most artistically worked together,
and entered by a hole just large enough to admit the body of the bird.
Of these compartments the hindermost is the largest, and so raised as to
remain dry should heavy rain penetrate the outer parts of the nest; so
excellently, however, is the entrance constructed, that such accidents
but rarely occur, or, if water should break through, are readily and at
once repaired. The large back chamber is covered with a soft bed formed
of various vegetable materials, for the reception of the eggs, which are
hatched by the united attentions of both parents; the centre apartment
serves as a pantry, and usually contains a goodly supply of provender;
while the small outer compartment is employed as a guard-room, from which
a strict watch is kept in case of approaching danger, the vigilant owner,
according to Verreaux, lying flat on the ground as he reconnoitres, and
keeping his head protruded through the entrance-hole. The young when first
hatched are almost naked, with but a very slight development of greyish
brown down. They grow slowly, and are tended with much affection by their
parents, who feed them principally at early morning and evening.
