Interesting Fact: Ruddy Ducks are very aggressive toward each other and toward other species, especially during the breeding season. Unlike most ducks, they form pairs only after arriving on the breeding grounds each year. Males perform unusual courtship displays in which they stick their tails straight up while striking their bills against their inflated necks, creating bubbles in the water as air is forced from their feathers. They punctuate the end of the display with a belch-like call. ( https://www.allaboutbirds.org/guide/Ruddy_Duck/lifehistory )
Three ducks are in a pond.
One went “Quack quack!”
And the other duck said “Thats funny I was just about to say that!”
Interesting Fact: Ruddy Ducks lay big, white, pebbly-textured eggs—the largest of all duck eggs relative to body size. Energetically expensive to produce, the eggs hatch into well-developed ducklings that require only a short period of care. ( http://www.allaboutbirds.org/guide/Ruddy_Duck/lifehistory )
