Breeding information

Breeding season: Jul - Mar Eggs: 2 - 4 Incubation period: 16 - 18 days Fledging age: 14 - 17 days

Given the right conditions, Grey Shrike-thrushes can breed any time of the year.

Nest

"bungobittah", "malunna" = nest [Aboriginal]

Type: Bowl Material: Broad leaves or bark strips with grass lining Height above ground: 0-2 m

Grey Shrike-thrushes are usually ground-nesting birds. Their nests tend to be hidden between grass tussocks or near the base of a shrub, in dense underbrush. However, we show here an example of a nest in vines ranking up a tree trunk.

[Mt. Kaputar NP, NSW, September 2008]

The nest shown below was still under construction by the bird in the photo above and its partner; since they were still carrying mostly bark for the outer walls, it is possible that finer material for lining the inside was still to follow.

Behaviour

Social behaviour: Territorial Mobility: Sedentary/dispersive Elementary unit: Solitary/pair

Grey Shrike-thrushes can be very curious - in some cases so much so that it gets them into trouble.

Call(s)/Song

For this species we have recorded the following call(s)/song. The interpretation of their meaning is our own; comments and suggestions for improvement are welcome.

Grey Shrike-thrushes are vociferous birds. Once their calls are known, one will hear them out in the bush frequently (usually getting in the way of recording other species' calls...).
