Bassian Thrush near Carrington Falls

Yesterday I went to visit my friend Jim Foran, who lives at the end of Cloonty Road, which runs out beyond Carrington Falls.

As I drove there, I saw a Bassian Thrush beside the road. just past the Kangaroo River crossing (the main bridge) on the Carrington Falls road. It was between the Bridge and the turn in to the main parking area leading down to the main lookouts. This is across the River, not the popular swimming hole used by the locals, which is accessed by veering right, before the River crossing.

The Bassian Thrush is a fairly secretive bird, a little smaller than a female Bowerbird (which looks somewhat similar). Bowerbirds hop with both legs simultaneously (they "bounce") whereas the thrush runs low to the ground and moves quickly, once it decides to go. When I flies it has a faint light stripe along the wing. It has a mottled chest, and a dark olive/brown back. It has a large dark eye, with a pale ring of feathers around the eye.

Bassian Thrush
Formerly known as "Ground Thrush"
I seldom see these birds around Robertson and never seem to get a decent photo of them. They seem to like dense thickets of vegetation, not necessarily rainforest. But I have seen them at the Robertson Cemetery where there is a dense patch of remnant rainforest.

However, I have more frequently seen them in wet sclerophyll forests around the bottom of Fountaindale Road (which is taller forest than at Carrington Falls, but not far away, "as the Thrush flies". I have also heard them and occasionally seen them beside the road to Belmore Falls, in what I refer to as sandstone scrub below Eucalypt forest, with many Banksias present in the vegetation mix. I know it is a very imprecise description, but it does not fit the classic definition of "wet sclerophyll forest" (as described by NSW Office of Environment - well certainly not the "grassy sub-formation") This is typical wet forest on sandstone around the southern Nepean River catchment and the northern end of the Shoalhaven River. 


I drove on to Jim's place, where there has been a lot of clearing, and saw another Bassian Thrush beside the road beside a stand of remnant (maybe regrowth) forest on black soil, over shallow sandstone.

Then as I drove back several hours later, I saw another Bassian Thrush, not far past the entrance to the Carrington Falls picnic area. Possibly the same bird as previously sighted.

From notes i have been receiving from the Canberra Ornithologists group, it seems Bassian thrushes are starting to breed in and around Canberra, so this seasonal factor might explain their apparent more obvious feeding beside roadways around the local sandstone forests.

Dry August, but the Macquarie Pass Orchids are going gang-busters

Well, it is official, August saw Robertson (well, my house at least) got 1.5mm of rain, in two separate "rainfall events". Yep, folks, its hard to get much drier than that.
But we got a lot of rain (428mm) back in June, and so the tiny Greenhoods down on Macquarie Pass are blooming as I have never seen them bloom before.
But before we delve into the intricacies of thousands of Greenhoods, and Maroonhoods, here is a bird which brazenly walked across the roadway, in the gaps between heavy traffic rolling down the Pass. It is a native thrush, about the size of a European Blackbird, (slightly heavier, in fact).
It is a Bassian Thrush (which I once knew as a "Ground Thrush" - before the taxonomists brought Australian bird names into lock-step with the international naming conventions).

"If a Bassian Thrush is disturbed it often runs a short distance and then freezes, relying for defence on the camouflage of its mottled plumage against the leaf-litter of the forest floor."
That quote from Birds in Backyards site perfectly explains what is going on in the next shot. It scurried to the edge of the leaf litter,t hen "froze". It took me ages to even realise I had photographed the bird in the leaf litter. The yellow oval marks where it is. Look for the bird's eye.

Check out the yellow oval ring, then look for the bird's eye.
