Purple heron

The purple heron is a large bird that lives in marshes, swamps, reedbeds, and along rivers. This long-legged bird stalks its prey of fish, reptiles, amphibians, insects, and crustaceans.

Stepping slowly and silently on long, thin legs, the large-bodied, long-necked crane stalks its prey in the shallow water of its marsh home. Other purple herons live in swamps, along rivers, and in reedbeds. The heron's large, round, yellow eyes gaze sharply at the water looking for its next snack or meal, which is most often fish, such as eels, perch, sticklebacks, carp, bream, and pike. Other items on its menu include mollusks, frogs, water beetles, water voles, and small crustaceans. From the shore, it may snatch snakes, lizards, spiders, and mice. The heron may walk through the water or stand still waiting for prey to approach. Any prey within stabbing range of the bird's long, pointed, sharp bill may find itself sliding headfirst down the heron's long, slender neck. Early morning and evening are the most common feeding hours of the heron.

Standing straight with its neck stretched and bill pointed upward, the purple heron measures up to 31 inches (79 centimeters) from its toes to the tip of its bill. Despite its large size, it weighs only one to three pounds (1/2 to 1 1/2 kilograms). Its wingspan is 47 to 59 inches (120 to 150 centimeters). Purplish-gray and chestnut plumage covers the body and large parts of its wings, which also have some slate-gray flight feathers. The long, flexible neck is rusty-brown with black stripes on the back and white with black stripes on the front. Two long, dark plumes point backward from the top of the heron's small, thin head.

Like other herons, the purple heron has some feathers in its plumage called powder down which crumble into powder. The heron plucks these feathers and combs the powder into its plumage when it preens, or grooms, itself. The powder cleans dirt and slime from their feathers.

Clawless otters (Aonyx capensis), foxes (Vulpes), African marsh harriers (Circus ranivorus), snakes, and rats prey on the purple heron. When frightened or disturbed, the heron freezes in a crouching position or stretches its body, neck, and bill to camouflage itself in the reeds. Habitat loss is the greatest threat to the birds' population.

The heron mostly lives alone except during the breeding season. During the day, it feeds alone but joins several other birds in a roosting site at night. Mating season occurs in April and May in Europe and Africa and June and July in Asia. Pairs of males and females form in the winter before the migration to the breeding grounds. The courting process often involves flying in circles and chases while in flight, a certain kind of dance, and noises made by clapping their bills. In the breeding grounds, a pair usually hides their nest from the other birds. Sometimes they may nest close to a few neighbors or even within a larger colony. Nests are flattened areas of reeds with layers of reeds on top of the base.

The male assists the female in incubating 2 to 8 bluish-green eggs for 26 days. Each bird sits on the nest every three days. When the chicks hatch, their parents regurgitate fish for them until they can eat whole fish. Although the young herons may leave the nest one week after hatching, they do not try their new wings for the first time until they are 40 to 50 days old. They fly away and are independent of their parents at nine weeks old.

As conservationists have worked to study and protect the purple herons, they have placed bands on the birds' legs to identify and track them. The oldest banded bird lived a couple of months over 23 years.

Purple herons make various hoarse, croaking noises.

The lifespan of the purple heron is a maximum of 25 years in the wild.
