Computational bioacoustics has seen significant advances in recent decades. However, the rate of insights from automated analysis of bioacoustic audio lags behind our rate of collecting the data -- due to key capacity constraints in data annotation and bioacoustic algorithm development. Gaps in analysis methodology persist: not because they are intractable, but because of resource limitations in the bioacoustics community. To bridge these gaps, we advocate the open science method of data challenges, structured as public contests. We conducted a bioacoustics data challenge named BioDCASE, within the format of an existing event (DCASE). In this work we report on the procedures needed to select and then conduct useful bioacoustics data challenges. We consider aspects of task design such as dataset curation, annotation, and evaluation metrics. We report the three tasks included in BioDCASE 2025 and the resulting progress made. Based on this we make recommendations for open community initiatives in computational bioacoustics.

Tasks We are excited to announce the 2026 BioDCASE task line up! Multi-Channel Alignment Alignment Task 1 Bioacoustic and environmental recordings are often captured using multiple devices operating simultaneously, for example with passive autonomous recorders or animal-borne loggers. When such recordings are not temporally aligned, analyses that rely on relative …

Call for Task Proposals Submission are now open for 2026 The BioDCASE organisers invite proposals to organise tasks for the 2026 BioDCASE Challenge. This follows the success first year of BioDCASE. Task proposals follow the same format and selection criterion as DCASE: 1) scientific and technological importance of a task …

Workshop Recap In October 2025 we held the first BioDCASE workshop in person in Barcelona, as a satellite event of the 2025 DCASE workshop. There was a lot of lively discussion of both the current challenges in bioacoustics and their solutions. $(document).on('click', '.img-click', function() { $('#modalImage').attr('src', $(this …
