Grey-shrike Thrush (Colluricincla harmonica): is a medium-sized bird between 220-265 millimetres long. This species occurs in a number of geographical forms. The most common form is grey above with an olive-brown back and the underparts are greyish.
The Grey-shrike Thrush is widespread throughout mainland Australia, Tasmania and some forested coastal islands.
The species may be observed singly, in pairs or family parties.
The nest is a large cup or bowl constructed of strips of bark, grass and other material. Nests are built in tree forks or cavities, vines against house walls, downpipes and in sheds. There are usually 2-4 white eggs with red-brown and blue-grey speckles.
The Grey-shrike Thrush has a beautiful and distinctive call. It is no coincidence that the species name is harmonica.
The Grey-shrike Thrush has adapted to human habitation.
We have Thrushes that have nested in the garden and structures at Yallaroo for many years. They have nested in a banana passionfruit vine, a native Clematis vine and in our plastic-covered propagating igloo.
A pair of Grey-shrike Thrushes built a nest in the corner of our igloo about three years ago (see right image).
Since then the nest has been used at least five times. Two or three eggs were laid each time. In 2008 the nest was used successfully in September and again in November. This would have to be the ultimate in avian recycling.
