The behavior and chatter of chickens is well studied. Although not all the mysteries of a hen's cackle have been revealed, there's a pretty good understanding of chicken talk. They're extremely simple creatures, after all.
I don't know how well duck talk has been studied, ducks like the mallards on my river, but I suppose, considering that a chicken can be understood, that I can speculate the ducks are having a fine time this morning as the gale howls down the stream in freezing temperatures.
While we cringe and huddle inside, the ducks are dipping and paddling almost joyously. Some fly in, some fly out of the throng, the ladies quacking greetings and departures (boys don't quack). One could probably resent them for their giddiness in such miserable weather OR...we can be glad someone, at least, is having a good time.
How's the weather? Just ducky!
