Concerning The Great Blue Heron Bird

A great blue heron wades across still water.


The great blue heron is a large bird that can be found in many places throughout the world, but most prominently in North America. These magnificent birds were originally described by Carl Linnaeus in the 1700s and consists of several subspecies. The bird is very well-known and has been well-documented by scientists since its discovery.


Appearance


The dull gray and gunmetal blue feathers give the bird its name.


The great blue heron is a tall, slender bird with a long neck and significantly bulkier lower body. The back of the neck is grayish-red, almost rust-colored, while the front is black and white. Its head is pale with a white face and and two black stripes running from its eyes to the back of its head and an orange bill. Most of its body feathers are a mix of dull gray and gunmetal blue, giving it its name. There are usually streaks of black and white lining its underbelly.


Size


The great blue heron is a relatively large bird, and is in fact the largest heron in North America. From head to tail, the heron ranges from around 35 to 55 inches, with a wingspan measuring between 66 and 79 inches. On average, the birds top out around 4.5 lbs. A subspecies, the great white heron, which is native to Florida, is about a quarter smaller.


Habitat


Great blue herons inhabit wetlands and still, shallow waters. They live in marshes, swamps, flooded meadows and along almost any shoreline in both freshwater and saltwater environments. The herons can be found almost universally throughout North America, including Alaska and most of Canada, extending down to northern and central Mexico. There are vagrant populations reported in Hawaii, Greenland and England.


Diet


Blue herons are not picky eaters. Though their diet consist mainly of small fish, they've also been known to eat turtles, lizards, frogs, small mammals, crabs and other birds. They do not chew their food and instead swallow it whole. The heron hunts by wading through the water and spearing any passing fish or small prey item, then tossing it into its mouth and gulping it down. Because of this behavior, herons have been known to choke on prey items too big for them to swallow.


Reproduction


Herons are colony breeders, meaning that dozens or even hundreds of individuals will find a place to set up a rookery (referred to as a heronry with herons) consisting of between five and 500 individual nests. The females will lay around four to six eggs, which are then incubated for around a month before hatching. The babies are fed by both the male and female parents; they regurgitate partially digested food directly into their babies' mouths.
