Immature Common Merganser Diet

Common Mergansers are primarily fish-eating ducks. Young mergansers require over half a pound of food per day during their first summer, and often supplement their fish diet with insects, mollusks, crustaceans, worms, frogs, small mammals, birds and plants. The pictured immature Common Merganser had just downed a crayfish when it spotted a frog which it succeeded in catching and eventually swallowing.

    Nice blog and amazing capture! That looks like decent-sized frog putting up some fight here! But in the end the bird was able to win the battle and gulp that whole thing down okay really?? It seems like it would have trouble fitting down that long/skinny neck. Also, if actually eaten, does the unlucky prey get swallowed kicking all the way as well?!
