Blue Wrens: Our Blue Wrens are very active in the garden. A
pair of these small cheerful birds nested at least three
times in our garden in spring 1999. They raised four fledglings and
constantly moving through our garden devouring large numbers of
insects. They are very efficient agents of insect control. They
chose Grevillea rosmarinifolia as their nest
construction sites. Their first nest was constructed in
September. No young Blue Wrens appeared from this nest. Instead a
Bronze Cuckoo was the result of their labours. The male and
female wrens spent a busy three weeks or so feeding this
interloper that was twice as big as the parents. Blue Wrens are
common throughout eastern Australia. They are about 140 mm long.
The males are glossy blue-black on the head, throat and back (see image). The
females are mouse-brown with whitish chest.
