Juvenile Little Blue Herons are anything but blue. They hatch pure white and gradually turn blue through successive molts. They are similar in size to Snowy Egrets and often mistaken for them, especially if they are wading. But the Little Blue doesn’t have the distinctive yellow feet, black legs or black beak of a Snowy Egret. This young Little Blue Heron has green legs and feet and its bill is blueish.
