Red-necked Grebe – Muggers

    [Calls of the Red-necked Grebe on a northern lake]
Few sights are as endearing as a mother Red-necked Grebe with three stripe-headed downy chicks nestled on her back. As soon as the last egg hatches, the youngsters climb onto the parent and they leave the nest behind, gliding quietly over the water. This species breeds along the shores of northern lakes, with many other grebes and ducks, including Mallards.
[Female Mallard quacking]
So why do Alaskans, with disgust in their voices, call this bird the “Mugger”? And scientists refer to the bird as highly aggressive?
[Call of Red-necked Grebe]
Well, these grebes are excellent divers and can swim underwater, coming up from below to attack other water birds. They’ll snatch newly hatched Mallard chicks and pull them down.
[Call of Red-necked Grebe]
Does the Red-necked Grebe deserve such a name? It is difficult for us to accept a bird killing another bird when the grebe doesn’t eat what it kills. But what appears to us, in Tennyson’s words, as nature “red in tooth and claw” may be the functioning of a balanced ecosystem.
 [Red-necked Grebes and Mallards]
