Now to really bore everyone. I've been spending time in Namadgi National Park enjoying a new hobby of recording animal and bird noises.

It's a fairly simple procedure involving a voice activated recorder (the dictaphone type) an external lapel microphone and a little plastic for weatherproofing.

Depending on the amount of bird chatter and the quality (expense) of batteries used the recorder can run for around three days and can record anywhere between a minute of recording if there is not much activity and two and a half hours on a good session.

A piece of agricultural pipe protects the recorder and is fixed horizontally on a tree and the microphone leads to an upturned cup suspended as high as I can reach above the ground. I have managed to record some extended sound files of a few different native species who's calls seem to me to be more chorus like in the bush. No interfering noises from surrounding suburbs and a wider variety of species.

Having said all that this post is not about bird recordings. Its about two recordings that have me baffled. The first was recorded in November in the dead of night. Now everyone is going to think I'm nuts but the first recording involves what seems to be 'knocking' noises that must have been made by 'something'.

There are a series of loud knocks that sound, to me at least, like rocks or stones knocking together. Could be natural but having spent many, many nights over the years in the mountains I can't put my finger on the source. I have heard the 'cracking' of granite exfoliation (Rocks in the park peeling somewhat like an onion) in Namadgi, ,a distinctive sound, and trees and limbs fall but this is nothing like it. You may be able to identify it...

The second recording over New Years was just as weird but different... a tentative tampering of the microphone that was suspended 7 feet above the ground on a thin sapling (that wouldn't have supported a possums weight) and the unmistakable sound of 'breathing' into the microphone cup. I am interested in knowing what 7 foot tall animals we have with a delicate touch roaming the park...

Just seemed odd enough to perhaps be interesting...

Namadgi National Park comprises 106,095 hectares, over a thousand square kilometres, with some valleys and ravines not seeing humans for decades.

Now not to scare the kiddies but who really knows what's out there?  A friend of mine may have discovered a new glowing insect in a national park nearby. They fly, glow several colours and can (occasionally) be photographed on trail cameras taking pictures continuously every one second.

As yet though a commercial 'bug catcher' has been unsuccessful. CSIRO can't identify a glowing species there and can't help further without a specimen. Not everything is known of the mountains yet I am sure. It has a few secrets to reveal even in the 21st century. Anyway... the things I do to entertain myself.

Strange stuff happens in Namagi... Happy camping!
