Current research highlights performance constraints on song production that may be influenced by variation in bill morphology. Darwin＇s finches are a model system for studying the relationship between morphology and song performance, with previous studies suggesting that lower vocal performance is correlated with larger bill size. Here, we tested for a relationship between bill morphology and vocal performance in Darwin＇s Small Tree Finch （Camarhynchus parvulus） on Floreana Island. We found no evidence of a correlation between bill morphology and vocal performance. This finding is in agreement with prior study of the Small Tree Finch, but contrasts a greater body of work addressing song in Darwin＇s Finches. We discussed our findings in the context of ecological divergence, and ecological variation across species.展开更多
