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.
