Cygnets of the Mute Swan.
The Mute Swan is one of the heaviest flying birds, with males (known as cobs) averaging about 26 lb and the slightly smaller females (known as pens) weighing about 20 lb.
Young birds, called cygnets, are not the bright white of mature adults, and their bill is dull greyish-black, not orange, for the first year. The down may range from pure white to grey to buff, with grey/buff the most common. The white cygnets have a leucistic gene. All Mute Swans are white at maturity, though the feathers (particularly on the head and neck) are often stained orange-brown by iron and tannins in the water.
