When the sun smiles on us with warm rays to brighten a cool winter day, what better way to spend a liesurely afternoon? This Mallard duck couple pause to enjoy the mild waters of a Palo Alto Business Park pond. Shouldn't they have flown south for the winter? Mallards are the most common ducks in America, and will migrate if necessary to breed and survive the harsh climates. However, I believe life around here is so enjoyable they've become permanent residents.
