AviaNZ birdsong analysis software

AviaNZ version 1.0 is released! The program is easy to use and equipped with the essentials for spectrogram reading, analysis, manual annotation, and also few other stimulating options to the next stage of the development: automated analysis of your field recordings. You can download the software along with the user manual following the links below. We welcome your feedback and it is very important to us as we continue developing AviaNZ.

Sponsor a kiwi  
To track and study our kiwi, they each need individual radio-transmitters and we need radio-telemetry equipment, batteries, and cameras to be able to follow them. In total, we spend $470 per kiwi each year and we would like to ask you to sponsor this cost for one or more of our birds.


Marsden Fund for AviaNZ

Stephen Marsland and Isabel Castro received Marsden Fund in this latest round to work on their project AviaNZ: Making Sure New Zealand Birds Are Heard.

New Zealand has amazing birdlife: nocturnal parrots, birds that can't fly, and birds that turn up after 50 years of being thought extinct. Unfortunately, many native species require wildlife management programmes, and they are hard to monitor: they are often well-camouflaged or nocturnal. How can you discern what works in wildlife management if you don't know how many animals there are and how the number changes? Most birds make sound, and so there is a real need for a system that can detect, recognise, analyse, and infer bird populations using automated sound recorders. However, data from these recorders is noisy and extremely variable in factors such as volume. In this project we will work to reliably detect and recognise birdsong from these recordings, and estimate the abundance of birds from the number of calls, by developing mathematical and computational tools to analyse sound, and combining them with ecological experiments to understand how calls relate to population estimates. This inter-disciplinary project will combine fundamental and practical work in theoretical and experimental science to develop sound solutions in both areas. Our work will be made publicly available through our AviaNZ software platform, which is already used by conservation groups across the country.
