Interview: Dr. Rosalind Renfrew on the Bobolinks’ winter diet

You’ve no doubt seen the Bobolink in Vermont. It’s a medium sized American songbird–black underneath and white on the back. But where the Bobolink spends its time far away from Vermont is now a cause for concern. Dr. Rosalind Renfrew of the Vermont Center for Eco-Studies is conducting a study into some new dietary habits the Bobolink has picked up in its winter home. Dr. Renfrew speaks with VPR’s Mitch Wertlieb.
