A female Hooded Merganser on a wilderness lake north of Montreal must have had a big appetite or a powerful yen for frog legs, judging by these pictures. The large bullfrog put up a 10-minute fight but the duck finally managed to manoeuvre the frog head-first into its bill and swallowed the frog whole. Mergansers normally eat fish. They have fine tooth-like serrations along the sides of their bills which help in capturing slippery fish -- or frogs, it seems.
