RealBirdID: Benchmarking Bird Species Identification in the Era of MLLMs

arXiv CS.CV

ArXi:2603.27033v1 Announce Type: new Fine-grained bird species identification in the wild is frequently unanswerable from a single image: key cues may be non-visual (e.g. vocalization), or obscured due to occlusion, camera angle, or low resolution. Yet today's multimodal systems are typically judged on answerable, in-schema cases, encouraging confident guesses rather than principled abstention.
