  1. Kroodsma makes a convincing case for their being two species in The Singing Life of Birds. But I guess a paper has yet to be published, which would be required for the AOU to take action.

    I certainly wouldn’t complain about their being more wrens to see. Wrens have to have the most personality/gram of any bird!
