North American Robin
Two winters ago, I observed a North American Robin (Turdus migratorius) catch a Stickleback (species ?) in an area of open water on a frozen urban pond. The open water was created by a seepage of water along the edge of the pond and hundreds of small Stickleback and another species of minnow swarmed in the open water. The remainder of the pond was likely low on oxygen and the oxygen rich waters at the opening drew the fish to it as well as a flock of about 50 - 100 Robins. They spent most of the winter in the area and were interesting to watch as they captured the fish which came within reach of their beaks.
I had heard about American Robins eating fish (minnows) in the winter on a pond near Saskatoon but this was the first time I observed and photographed this behaviour.
