-**Task.** Given a detected zebra finch vocalization and the set of birds visible at that moment, determine which bird produced the call.
+**Task.** Given a detected zebra finch vocalization and the set of birds visible at that moment, determine which bird produced the call. Caller identity is verified physically from on-body accelerometer vibration; the accelerometer channel is withheld from benchmark models and used only by an oracle ceiling.
 
-V33DA provides 33,625 vocalization events from 10 individually identified zebra finches across 3 experiments (2021--2023), each with synchronized 5-channel audio, multi-view video, 3D pose, FM radio telemetry, and accelerometer-derived ground-truth labels.
