Huge Pike Can't Swallow Big Duck

There's no shortage of videos floating around that show poor, cute, fluffy ducklings getting devoured by pike. But this one is a bit different. Here we have a truly massive northern clamped tight on a fully grown bird. To my eye, the pike—while long—looks skinny, which suggests that perhaps this is a case of feeding desperation. I'm going to assume the pike eventually won after drowning the duck, but they initially both seem rather unfazed in this standoff.
