A collection of high-frequency echolocation calls of Australian bats.<br><br> It contains calls from previously available collections such as Pennay et al. (2004), Bat Calls of NSW and Milne (2002), Key to the bat calls of the top end of the Northern Territory, calls collected by members of the Australasian Bat Society during conferences and Bat Blitz's held in Tasmania, Queensland, Northern Territory and South Australia as well as those donated by individual bat researchers.<br><br> The collection also includes long-term monitoring (funded by TERN) at a number of Queensland sites: Cape Hillsborough National Park, Kings Plains, Fanning River, Fletcherview Research Station, Carnarvon Station Reserve and Bunya Mountains / Dalby.<br><br> This collection includes zc, wav, identified and unidentified calls, with call meta data such as location (GPS), call collector, call identifier (where relevant), how a call was identified etc noted in the metadata associated with each sound file.<br><br> Perhaps most significantly, this collection includes over 100,000 calls recorded by Chris Corben, many of which are identified to species. We thank him for his incredible generosity and contribution to bat work internationally. The earliest calls date to 1989, prior to Titley's involvement, and probably involved Chris with his laptop and an ultrasonic microphone plugged into it!

<p>This dataset contains audio files from Warra Tall Eucalypt SuperSite. Warra Tall Eucalypt SuperSite was established in 2012 and is located in a stand of tall, mixed-aged <em>Eucalyptus obliqua</em> forest (1.5, 125 and &gt;250 years-old) with a rainforest / wet sclerophyll understorey and a dense man-fern (<em>Dicksonia antarctica</em>) ground-layer. The site experienced a fire in January 2019, which consumed the ground layer and killed a high proportion of the understorey trees, but stimulated dense seedling regeneration. For additional site information, see <a href="https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/warra-tall-eucalypt-supersite">Warra Tall Eucalypt SuperSite</a></p> <p>In 2012 an acoustic recorder was set up to collect audio data for a total of 12 hours per day, split between six hours around dawn and six hours around dusk. The recording schedule aimed at capturing morning and evening bird choruses while minimizing memory and battery requirements. A long-term spectrogram has been generated for each audio file to aid in data exploration. The sensor also recorded temperature, minimum- maximum- and mean-sound pressure levels. The sensor stopped working in 2019 when it was destroyed by a fire.</p> <p>Acoustic indices and false colour spectrograms were created for the recordings. Acoustic indices are summaries of the distribution of the acoustic energy in a recording. They are particularly useful for the analysis of long-term recordings of the environment and can be used to identify sound sources of interest, characterise the soundscape, aid in the assessment of fauna biodiversity, monitor temporal trends and track environmental changes. False colour spectrograms are visual representation of individual acoustic indices or combination of multiple indices. They can highlight the presence of specific sound sources, e.g. birds, insects or weather events, providing a tool for navigating long-term recordings.</p> <p>Data are made available through the data link.
