What is it about?
It was believed that sub-oscines that called with different dialects were sub or distinct species. Genetic testing of bellbirds with two different dialects show different results. Combined with behavioral evidence, we conclude that the Three-wattled Bellbird learns its dialect.

Why is it important?
It was previously believed that sub-oscines did not learn dialects. This study shows otherwise.
