Overview:</span></strong><br>
In this challenge, participants will develop and evaluate algorithms for detecting and tracking small birds in footage captured by UAVs. A distinguishing feature of this task is that both
<b>Multi-Object Tracking (MOT)</b> and <b>Motion-Aware Tracking</b> are required. The development of methods capable of overcoming real-world challenges such as
<b>occlusions, motion blur, and rapid movements</b> is expected.<o:p></o:p></span></p>
