Following up from a post by Martyn Stewart on the aftermath of the Black Saturday fires Nicole and I made a trip up to visit the area along the Acheron Way.
The first stop was shortly after dawn was at the Acheron Gap. The area is Cool Temperate Rainforest (see midway down this page on the Victorian Rainforest Alliance website for pics of the Acheron and Cement Creek areas) and was untouched by the fires.
The mics were placed under a dripping tree -- another field craft lesson -- so there is a quite a bit of "water drops on ground atmospherics". Very prominent in the recording is a Superb Lyrebird calling from the top of a tall tree. I'm not sure if the bird was alarm calling due to my presence nearby or if this is a normal part of their repertoire?
Update: According to Vicki Powys the lyrebird was VERY alarmed by my presence. Ooops!
Recording at the Acheron Gap
Recording Gear: Tascam HDP2 (Oade Super Mod), AT3032 in a parallel boundary array
Conditions: Approximately 12C, Misty, damp
This recording was made at Gundabooka NP shortly after dawn. I'd initially positioned the mikes in a spot that had few birds calling so I moved the mikes about 100m to a stop just off the road to Bennet's Gorge where Grey Shrike Thrush were calling. Species that can be heard in the background include Crested Bellbird, Rufous Songlark and Blacked Eared Cuckoo and Horsfield's Bronze-Cuckoo.
The recording was made with an Oade Brothers modified Tascam HDP2 and a pair of Audio Technica AT3032 omnidirectional Mics.
I've added a short 7 second section of predawn stillness to the end of this recording to give an idea of the level of noise generated by the recording chain.
Gilbert's Whistler recorded New Years Eve morning at Terrick Terrick National Park, roughly 230km north of Melbourne. Conditions were somewhat windy and not especially conducive to recording.
This clip is a after and before comparison of the use of noise reduction on nature sound recordings. While the Izotope RX denoiser plugin is quite effective at eliminating background hiss examining the clip using a sonogram shows that some fine detail in the recording is also lost.
This chorus of Spiny-cheeked honeyeaters was recorded at Roundhill NR in NSW just before sunrise. A spotted night-jar also makes an appearance close to the start. Red-capped Robin can be heard through the later part of the recording.
The original recording has a heavy layer of hiss which is probably due to the recorder running on close to flat batteries - they died completely shortly after I finished record this. I've used a demo copy of the Izotope RX noise reduction plugins to reduce some of the more prominent hiss and ApEQ to reduce the low frequency wind rumble.
Dawn at the Bird Paddock - Clarkesdale Bird Sanctuary
On the weekend of 3-5th October 2008, the Australian Wildlife Sound Recording Group held a small gathering of Victorian members at the Clarkesdale Bird Sanctuary near Linton. Located about 40km South West of Ballarat the Sanctuary provided a relatively quite location, with only a small amount of local traffic and only occasional passing jets.
The first evening was very wet, and things didn't look too promising, but I dragged myself out of bed at around 5am, and walked the 6-700m to the recording location in the dark.
This recording captures the sound of the "Bird Paddock" shortly after first light. and you can hear Pallid Cuckoo, Eastern Yellow Robin, Grey Shrike Thrush, Crimson Rosella, and Long Billed Corella, and many other species.
This was the first AWSRG gathering I'd attended and it was an absolute pleasure to meet and talk with some kindred spirits.

Recorded at Gamma State Forest, Near Eungella, Queensland, in fairly windy conditions.
This is an edit of a 18 minute recording of the dawn chorus at made at the Spring Creek camp ground, in the Mount Samaria State Park. The morning was cold (approx. 0degC) and clear. Birds that can be heard in this recording include Superb Fairywren, Scrub Wren, Eastern Whipbird, Gang Gang Cockatoo and many more....
The recording was made with a pair of AT3032 mics, a diy stereo mic preamp and Sony Minidisc recorder.
After waking to find the power switch on the mic preamp had been bumped when loading into the car and I had to change batteries in freezing cold conditions I decided that a recorder with built-in xlr mic inputs and phantom power was the only sensible way to go....
This is one of the first recordings I made. This was madeusing an Audio Technica AT897 shotgun mic and Sony Minidisc recorder on a BOCA bird survey of the Yellingbo Reserve, east of Melbourne.
Black Winged Stilts recorded at the Western Treatment Plan.
Recorded with AT3032 mounted in a Telinga dish, the file has been cleaned up with a low shelf filter to drop low frequencies by 6dB to reduce traffic and jet rumble.
