Occasionally, when my attention wanders from a skyward gaze, I reflect on what lies under my feet.
Sadly my understanding of our local geological landscape is scant, but I’ve always had a fascination for rocks. This road cutting, just to the east of Joyce’s Creek, is notable as it lies very close to the Campbelltown fault. I’ve often stopped to photograph the exposed face of the cutting on trips home from the Moolort Plains. The rocks were apparently formed from deep marine sediments between 490 and 460 million years ago … that’s about where my knowledge starts to peter out!

I have a habit of returning to the same places in the local landscape, often over successive days. One of the narrow tracks running west off Mia Mia Track is a personal favourite that I tend to visit at least once every fortnight. Two excursions this week, the first on Thursday and again last night produced a very different set of birds.
Brown Thornbills were ‘hiding’ during my first visit, but were the highlight under dull skies last night. Also of note were Buff-rumped Thornbill, White-eared Honeyeater, Scarlet Robin and a small flock of Rainbow Bee-eaters, none of which I’d observed the day before. The diverse understorey of wattles (especially the Rough Wattle), peas and heath are a key reason for this sites avian richness.

… and that leaf again!
I dragged myself away from the water last evening and ventured into the bush along Mia Mia Track.
It’s very, very dry!
There was reasonable numbers and variety of birds. Along with those shown below I also observed: Grey Shrike-thrush, Yellow-tufted and Fuscous Honeyeater, Yellow Thornbill, Spotted and Striated Pardalote, Rufous Whistler and Little Eagle. Not too bad for a 30 minute walk.

This Great Egret sequence was the highlight of a visit to Cairn Curran last evening.
Somewhat unusually there were two individuals feeding close together in the shallows.

The day before it was a Double-banded Plover amongst the Red-capped Plovers at Cairn Curran. This time it was a lone Red-necked Stint, enjoying the company of others as it foraged on a small area of exposed mud near Captains Creek.
This tiny wader has featured numerous times before on the blog … here in flight March 2015 and another note around that time where a few birds were seen in breeding plumage before migration.

Todays post is dedicated to the memory of Joan Butler, who passed away last week aged 84 years. Joan had a wonderful love and knowledge of Australian birds, especially those from places around Newstead including the Sandon bush and Muckleford forest. Her interest stemmed from when she was a child attending school in Sutton Grange … I especially remember her story of the Grey Shrike-thrush that came each spring to nest on the window sill, opposite the teacher’s desk. Joan lived for many years at Captain’s Gully overlooking Cairn Curran Reservoir.
Another visit last evening to Cairn Curran to check on the Red-capped Plovers.

It wasn’t a surprise to spot a ‘loner’ in their midst, a Double-banded Plover.

This species is a regular winter visitor to Cairn Curran, albeit in small numbers … I think the most I’ve ever seen would be three of four individuals together. While they are not dissimilar to the more common Red-capped Plovers, there are some distinct differences … size (DBPs are about 30% larger), facial markings (DBPs have a buff wash on the face) and leg colour (greenish in the DBP and black in the RCP). Double-banded Plovers, as their name indicates, also have two breast bands but these are often not prominent in non-breeding birds. They also have a bulbous head, compared to the flattened crown of the Red-capped Plover.

Double-banded Plovers breed in New Zealand – some of the population nest on inland riverbeds, and these birds tend to migrate to Australia. Others nest on coastal lagoons and estuaries, and some lowland pasture, but these birds tend to be more sedentary. To my knowledge this pattern of migration and breeding is unique amongst Australian and New Zealand birds.

On Saturday morning I heard, for the first time this autumn, the unmistakable piping call of the Eastern Spinebill.
This diminutive honeyeater is a cool season migrant to the Newstead district, usually arriving in April in our garden to feed on flowering Grevilleas and Correas. They linger until late winter most years before heading back south to higher altitudes to breed. Not far from here, at places such as Daylesford, Eastern Spinebills can be found year round.
The juveniles generally arrive first, perhaps they’ve been ejected from breeding territories by their parents – the adults appear a few weeks later in my experience. This years sighting is somewhat earlier than usual, last year I spotted my first spinebills around the 20th March at Rotunda Park and in preceding years its been well into April before the first birds arrived. As always I’d be keen to learn of other local observations.
