What justifies to keep Nesospiza and Rowettia as different genera of Melanodera? I would put everything in one genus
Another good question is how on Earth did those little Melanodera tanagers colonise such far-flung islands not once, but actually twice?
I doubt very much that either current mainland species could repeat that feat.
