Fair weather suits finches just fine

Cumulus humilis, Flagstone Creek.

Dry conditions have settled in this spring in the Lockyer Valley, with less than half the monthly rainfall average being delivered for November.

I headed out there this week to study cloud formations in the hills surrounding Flagstone Creek, but with such a lack of moisture in the air, there was little to see unfortunately.

I have been wanting to test out my cloud identification skills ever since I learned that meteorologists actually assign each variety a genus and species name, just like a living organism.

On this particular morning, however, all I could see for the most part were small, misshapen strands of condensation in the air, a formation known as Cumulus fractus.

These can dissipate as easily as they form, but where ridge lines and mountaintops feed them with updrafts full of warmth and moisture, they can develop into the more structured cumulus form (Cumulus humilis) that most people are familiar with.

Indeed, by mid-morning, this was what was happening on the horizon all around me.

While I enjoyed my cloud-watching, there was a lot of wildlife that competed for my attention also.

Most remarkable were the flocks of zebra finches (Taeniopygia guttata) bouncing through the air from shrub to shrub.

Having never seen this iconic bird of the Australian outback before, I was delighted to get a good, up-close view of a male gathering nesting material along the roadside.

This observation, along with some of the flock members being immature birds, suggests that they are actually breeding residents of the area.

Other creatures seen on the gravel road verge included large numbers of caper white (Belenois java) butterflies and yellow-winged locusts (Gastrimargus musicus).

Huge meat ant (Iridomyrmex species) nests offered another example of just how well insects can thrive in hot, dry weather.

Further afield on the parched hillsides were remnant trees from the scrub that once cloaked the area, with the narrow-leaved bottletrees (Brachychiton rupestris) standing out in particular.

Luckily, there are bigger clouds and soaking rains on the horizon, with a week of thunderstorm activity forecast from this weekend onwards.

Keep an eye out for that most impressive of clouds, the Cumulonimbus incus!

Suspicious locals, Flagstone Creek.

  2. That must have been a treat to see the Zebra Finch. Great capture. I wish we had some rain clouds here now.

    1. It certainly was, Diane! They are not a bird I expected to see in SEQ.

      The rain has turned out patchy but decent - hope you got some! :)

  3. looks awesome! Yeah, here on the coast we've had a fair amount, which has brought out frogs (of course) and large numbers of birds! come to the sunshine coast and see what you can find!

    1. Funny you should mention it, but that's exactly my plan for this weekend! :)

    2. What a coincidence! We recently just had a storm which brought a couple of frogs out and lots of Channel Billed cuckoos and Koels.

North Queensland Trip, Part 1.

Eungella National Park Eungella National Park location; Image courtesy of Google Maps. My home state of Queensland is a huge place. Bigger than any of the United States, it is considered the sixth largest sub-national entity in the world, behind such remote provinces as Nunavut in Canada, and the Danish territory of Greenland. Though I've lived in and travelled through Europe and Canada, much of my birthplace remains a mystery to me. To rectify this situation, I planned a road-tripping holiday this year with my sister and her partner, in the Northern section of the state. My first visit to anywhere in the Tropics, I have since returned home with some of the most amazing wildlife experiences possible!

Wild Plants of Ipswich

I've never really taken much notice of plants until recently, regarding them usually as just the thing that a bird perches on while you're watching it. This week I decided it was time to change that attitude by trying my hand at plant identification in Denmark Hill Conservation Park, located in the centre of Ipswich. The park is just 11.5 hectares in size, but preserves a patch of bushland that acts as an 'island refuge' in a sea of suburbia. I did my best to focus on the trees and not be too distracted by birds or the resident Koala   (Phascolarctos cinereus)  population, and came up with nine interesting trees and plants seen on the Water Tower Circuit.

Wild Queensland: Photos and stories from my roadtrip north

Earlier this month, I drove up to Airlie Beach in the Whitsunday Region to celebrate the 40th birthday of my close friend, Kat. Photo by Luke Martin. Our time there overlapped for one weekend, in which we enjoyed swims, drinks, hearty dinners and a sailing adventure around the islands. The celebrations and wonderful catch-ups flew by quickly, but when Kat and her husband Luke flew back down south on Sunday, I still had a week's worth of time at my disposal to explore the nature of Queensland's coast. I started with a journey into the forests of Conway National Park, just a ten minute drive east of Airlie Beach. I spent a sunny, humid morning walking up to the peak of Mount Rooper, through vine scrub and eucalypt forest. It was exhilarating!  I immediately saw a new species of bird for me in the carpark there, a female olive-backed sunbird (Cinnyris jugularis). After so much rain earlier in the week, the forest floor was also teeming with amazing fungi! After lunch back in town,
