Medial and lateral HVC ablations produce different effects on song production. A: prior to medial HVC ablation (PRE), bird 411 produces the canonical motif ABCDEFG with repetitions of syllables C and D. After ablation (POST), the bird produces the atypical transition F-E. B: prior to lateral HVC ablation (PRE), bird 512 produces the canonical motif ABCD. After ablation (POST), the bird produces the motif AB. Nonsong (NS) vocalizations are generally observed before the production of a new motif. Data from Basista et al. (2014).
