The best way to tell the difference between the common merganser broods and mallard broods is to look at the color of a duckling’s body and head.  Common merganser ducklings (bottom left) have grey bodies with white patches and a dark rusty-orange head.  Mallard ducklings (bottom right) have brown bodies with yellow patches and a brown and yellow head.

If the ducklings have ANY yellow coloration anywhere, it’s probably a mallard brood.

If you were able to take a picture of the brood with your camera, please upload it using the “Select File” button below.  (Your photo doesn’t have to be a close-up or even in sharp focus. We can often confirm it’s a common merganser brood just by looking at how the ducks sit in the water).
