A highlight of any trip to a place where there is water when you are young is feeding the Ducks… and so it was for me. My favourite park had a large lake and there you could feed the Ducks, Geese, Swans and Gulls whatever delicacy you brought them.
They loved sweetcorn, peas, oats, seeds or rice. These could be thrown into the water for them to squabble over or, if you were very brave, offered on a flat, out-held hand. There is nothing quite like the feel of a wide, flat duck’s beak in your hand as it gobbles up peas!
On one such outing, I learned that ducks use the serrated edges of the beaks—called “pecten”—not only like a comb as they preen oil into their feathers to keep them buoyant, but also to filter food from the water that is squirted out while they are feeding underwater. They have further finer filters inside the beak, but you can only see those if one opens its beak to “Quack” near enough for you to see it!
A pair of Ducks is monogamous, though usually only for a year. The duck does all of the brooding and rearing while the drake moults his handsome iridescent and flight feathers and looks more like a duck until autumn when he moults back out of his “eclipse plumage” and into his breeding finery once again.
