The tricolored heron (Egretta tricolor), formerly known as the Louisiana heron, is a small species of heron native to coastal parts of the Americas. The species is more solitary than other species of heron in the Americas and eats a diet consisting mostly of small fish. This species measures from 56 to 76 cm (22 to 30 in) long and has a typical wingspan of 96 cm (38 in). The slightly larger male heron weighs 415 g (14.6 oz) on average, while the female averages 334 g (11.8 oz). It is a medium-large, long-legged, long-necked heron with a long, pointed, yellowish or greyish bill with a black tip. Its legs and feet are dark. The plumage of the triclolored heron changes dramatically from its juvenile form to its adult form. Adults have a blue-grey head, neck, back, and upper wings, with a white line along the neck. The belly is white. In breeding plumage, they have long, blue, filamentous plumes on their heads and necks, and buff ones on their backs. (Source: Wikipedia.org, CC BY-SA)
