New molecular research shows that white eye birds (family Zosteropidae) form new species at a faster rate than any other known bird. Remarkably, unlike other rapid diversifications, which are generally confined in geography, white eyes diversified across multiple continents and far-flung islands. These birds were dubbed “Great Speciators” for this ability to rapidly form new [...]
