It’s been 5 years since the cycad sprouted new leaves, it’s just done it again! According to this University of Wisconsin page many cycads produce leaves, at most, once a year. Which I take means that it could be several years between growths. Before this year the last few years have been very dry here, I wonder if the cycad has been waiting for more water before sprouting.

Since the Covid restrictions and working from home I’ve been doing a lot more running on the local trails. While running down by Middle Harbour river in the winter months some days the water boils and churns like there’s something very large thrashing about down there! It’s happened on many occasions but it’s only been once or twice that it’s been close enough to get a decent look at. The thrashing covers a patch of water approximately 3×3 meters and is usually close to the shore. It can stop and start over a period of a few minutes, each time lasts between 5 and 20 seconds.

Even though the Channel-billed Cuckoo only visits northern and eastern Australia from around August to March I’m surprised not to have taken note of it earlier. It’s a distinctive looking bird, quite large with a huge beak and red eyes. In flight it looks sleek and almost hawk like. The other birds don’t take a liking to it ( and for good reason! ) and can be seen chasing and harassing it.

The water gum is a common tree found on the east coat of Australia from the Brisbane River in Queensland through NSW down to Gippsland region of Victoria. It flowers in summer with groups of small yellow flowers with 5 rounded petals.

While running in the rain I came across this group of sawfly larvae moving together en masse in the middle of the trail. I’m glad I spotted them, a misplaced foot could really have ruined their day!

I’ve seen these guys before, they are commonly known as spitfires due to their habit of regurgitating a thick yellow irritating fluid when they feel threatened. I stopped to take a few photos while my running partner caught up. She was a bit grossed out but fascinated too. I touched a few of them, they are soft and squishy, the hairs on their body are nowhere near as spiky as they look. When I got too close they would all start raising their tails and thumping them back to the ground, it was quite a sight! We said our goodbyes and left them where we found them, I hope they got where they were going to safely. See my previous post on Sawfly Larvae for more info.

Saturday morning after the hazard reduction burn. The smoke was choking, PM2.5 levels were close to 1000 µg/m3 for 4hrs

After last years terrible fire season I got interested in particulate matter air pollution from smoke and other sources and It’s effect on health. Inspired by this post I ended up buying some parts so that I could put together my own PM2.5 and PM10 detector. There are plenty of ready made detectors you can buy but I figured if I made my own I’d be able to customise it and add functionality that you’d normally have to pay a premium for. It’s also a lot of fun to build these projects and learn along the way!

Grey Goshawks are a frequent visitor to the area, up until now I’ve not been able to identify or get a good photo of one. Last week I heard the sound of a screeching flock of cockatoos off in the distance, as they got closer the sound got louder. They were swooping and swerving making a huge racket, in front of them was a hawk! It looked like they were chasing it away! A few days later I spotted it sitting in a tree out the back and managed to get these photos.

The Echidna, such an iconic Australian animal and unique too being one of only two monotremes, the other being the Platypus. We’re lucky enough to have Echidnas in the local area and even venturing into our yard from time to time. Last week I was looking out the window at home while making lunch and noticed what looked like an unusual rough clump on the ground. I went outside to have a look and it turned out to be a group of four Echidnas huddled together in the sun! They were not moving and appeared to be just relaxing. I’ve only seen lone Echidnas before, four in one place was amazing!
