  • Collared Sparrowhawk or Brown Goshawk?

    Collared Sparrowhawk or Brown Goshawk?

    For most of New Years Day 2022 in the Dayboro area it was incredibly wet (over 80mm fell in the morning) but at dusk the clouds cleared a little and I became aware of the shrill-call of an ‘Accipiter’ hawk from a nearby Hoop-Pine. My initial thought was that it was a Collared Sparrowhawk (Accipiter cirrocephalus) (from the higher-pitched repetitive sound), but when I started to photograph it thought that the tail-shape seemed incorrect and looked more like Brown Goshawk (Accipiter fasciatus) Both are currently regular in the area, but BGOS far more obvious/abundant. I recorded hand-held video but the quality was very poor, so I extracted the audio, have uploaded a small section of the video and the entire audio. Apologies for the video-quality (I appreciate that it’s hard to watch) but would love your thoughts.

    Note: The two images at the top of the post were taken locally (…and fairly recently) but are for content only and not the featured subject.

  • Which Buttonquail?

    Which Buttonquail?

    Recently I’ve been hearing a buttonquail (turnix species) calling from long-grass on the roadside near my residence, I’ve managed to get a few audio-recordings but no results on the camera-trap. I have had very brief views which suggested a rather large dark-brown bird, but there are also numerous Brown Quail (Coturnix ypsilophora) present here too. So far the general-consensus seems to be Red-backed Buttonquail (Turnix maculosa) but I’m not convinced by the poor-views that I’ve had.

    Please note that the RBBQ ‘featured-image’ is not the bird from the recordings and was taken (and donated) by John Weigel 9 years ago near Gold’s Scrub, Samsonvale.

    I’ve also posted this question on the forum at Xeno-Canto.

    The first audio-file was from a Sony PCM D100 hand-held recorder (27 December 2021).

  • Diamond Dove Dawn

    Lake Bindegolly, SW Qld, 06 June 2020

    This 8-minute recording was made on the bridge at Lake Bindegolly SW Qld at dawn on the 6th June 2020. It mainly features the calls of Diamond Doves, but you can also hear hundreds of Tree and Fairy Martins, the ‘trilling’ of Rufous Songlark and numerous Budgerigars, White-winged Fairywrens, Zebra Finch and a Willie Wagtail.

  • Lock-Down Sound-Recording

    During the COVID-19 Pandemic threat Queensland has had to endure similar ‘lock-downs’ to the rest of Australia but however (so far to date) we have been ‘permitted’ to exercise locally (…and in ‘isolation’!) therefore I have been taking the opportunity to record some ‘wildlife-audio’ on my own in local-parks, taking advantage of the reduction in ‘Anthropogenic-noise‘.

    These are some of the most recent-soundscapes, I have tried to keep them as ‘edit-free’ as possible, however on occasion there seems to be plenty of ‘noise’ and so I have applied some hi-pass filters and noise-reduction. There is also a ‘Mystery-call’ which I think sounds a bit like a Cicadabird but recalls a Leaden Flycatcher, possibly (?)
