STEIN: This strange sound is a male Ruddy Duck, performing his bubbling display.

When the sexes meet on the breeding grounds, usually a warm, weedy lake in the western interior, the males of these pudgy little ducks get right to strutting their stuff.

When a female appears, the male raises his long tail and his head, with feathers on it that look like horns. He inflates his neck, and faster and faster, strikes his chest with his bill. These blows force air through the feathers, causing the water to bubble. The male’s display ends with his head and tail jerking forward, and a low belching sound.

Whenever you hear this, watch for a bright rufous-red duck with black-and-white head and sky-blue bill. After the bubbling display, the male will usually run across the water with rapidly beating wings, his feet putt-putting like a little motorboat.

Stay by the water, and you’ll hear this motorboat alternating with the bubbling display again and again.
