Figure 2.
Nests owned by blue-capped (a, b) and red-cheeked (c, d) cordon-bleus.
(a) The nest built by blue-capped cordon-bleus was located at the upper
part of an Acacia tree (yellow circle on the left photo), and
there was a wasp nest (pink circle on the right photo) right next to it.
The outside of the nest was roughly covered with the flowers and stems
of Mollugo nudicaulis (the right photo, see also Fig. 5). (b) The
weaver nest was lined with fine grasses brought by blue-capped
cordon-bleus, and a male blue-capped cordon-bleu stayed inside (enlarged
photo below right). (c) Red-cheeked cordon-bleus used the weaver nest,
and there was a wasp nest below it (pink circle). (d) The nest (yellow
circle) was built by red-cheeked cordon-bleus in an Acacia tree,
accompanied by a wasp nest (pink circle and enlarged photo below).
