Disturbing: Children, dogs, and irate pond-keepers can all help to scare herons off, but these birds are surprisingly persistent creatures and they will return when you're not about, even if you're only just out of sight.
During nesting season, a heron may catch a fish every two minutes to feed its chicks. It is quite unlikely that a great blue heron will set up its nest in a neighborhood backyard. However, for those wishing to see the bird up close, a decorative pond stocked with small fish may prove irresistible for the heron.
Decoy Heron
But we'll let you in on a secret: Heron decoys don't work. At least not very well. Heron are smart animals, and they'll figure out pretty quickly that the bird staring at them from the edge of your pond isn't moving.Great Blue Herons typically eat fish, but sometimes also prey on other creatures like turtles, salamanders, snakes, and yes — rats and mice.
Answer: Baby ducklings could be among the things herons pick up near the shallows where they feed. Their preferred food, however, is frogs, fish, and other aquatic animals.
Herons much prefer fishing in the shallows, so ponds with steep sides and ample depths (1.2m/4ft or more), such as those found in ponds specifically for koi, will provide a good refuge for fish.
Night herons stand still at the water's edge, and wait to ambush prey, mainly at night. They primarily eat small fish, crustaceans, frogs, aquatic insects, and small mammals. During the day, they rest in trees or bushes.
But many do not know that herons are also active at night. Butler of the Canadian Wildlife Service, who wrote The Great Blue Heron (University of British Co- lumbia Press, 1997) and the great blue heron monograph in the definitive series The Birds of North America published by the American Ornithological Union.

Great blue herons typically nest in isolated areas amidst a colony of other great blue herons. While great blue herons don't mate for life, they do go through some incredibly difficult courtship rituals. Courtship begins when a female and male arrive at a designated breeding area.
Calls. Black-crowned Night-Herons give a barking squawk when disturbed. Males give a hissing plup to attract females. When parents arrive at the nest with food they give a series of guttural notes followed by a raspy woc-a-woc call.
Conclusion. Great blue herons are primarily fish-eating birds but can and often times do eat other critters such as frogs, snakes, amphibians, rodents, and even small birds.

What are some predators of Herons? Predators of Herons include foxes, minks, and raccoons. What are some distinguishing features of Herons? Herons have long, thin legs and pointed beaks.
The oldest wild great blue heron was said to be 23 years old, but most do not live so long. The average lifespan for a great blue heron is around 15 years. As with most animals, they are most vulnerable when they are young. More than half of the great blue herons born in one year will die before they are a year old.

The most obvious difference between a male and female great blue heron is size. Male herons are visibly larger than their female counterparts, typically weighing between 6 and 8 pounds. A female usually weighs between 4 1/2 and 6 pounds. The male heron's bill is longer than the female's bill.
Most small ponds are or quickly become bass heavy i.e. too many bass if many are not removed every year. A heron eats fish up to 6 to 8 inch generally but its eyes are much bigger than the stomach. It will strike out at larger unsuspecting fish.
While some nests are built on the ground near a water's edge, great blue herons mostly nest in colonies in trees near water. These colonies are called “heronries.†These nests can be 100 or more feet off the ground and can range from five to 500 nests per colony.
The blue heron symbolism talks about self-reliance and self-determination. Those with the blue heron spirit animal in the Native American tradition possess innate wisdom and strength that helps them maneuver and co-create their own situations and achievements in life.
These huge herons can crouch into a surprisingly small size. But the Great Blue Heron is not at the pond just to eat fish, oh no, this bird will also take down frogs, large insects, shrimp, crabs, small birds, chipmunks, squirrels, mice, snakes, turtles, baby rabbits and just about anything else that it can eat.
A DeKoi- It seems counter-intuitive to have a decoy of your beloved fishes as it would attract predators. But Herons especially will grab this non-moving plastic fish, giving your real fish time to hide.
It is illegal to shoot herons and egrets without a permit from the USFWS. A permit can be obtained by commercial fish farms to augment their on-going nonlethal harassment programs.
Birds Tell Us to Act on Climate
As many as 60 nests in a colony can create quite a frenzy! Nesting in large colonies helps protect the young from predators. But by this time of year, the adults and gangly young have left the nests to take up solitary lives along beaches, marshes, lake edges, and rivers.The herons and egrets are always solitary. Some days there will be a snowy egret, a great white or a great blue, but only one of each. Herons are know for their solitary feeding; egrets are less so. Egrets may start out on their own, but often wading birds of different species will cozy up to them.
However, most herons are thought to roost by night (usually in tall trees rather than on the ground), which leaves remarkably little time to find food and a great deal of down time.
Predators. Crows and ravens eat heron eggs. Hawks, bears, eagles, raccoons and turkey vultures have been known to prey on young and adult herons.

Except when they are breeding, herons spend much of their time alone, feeding in damp places or wading in water.
Great Blue Herons generally move away from the northern edge of their breeding range in winter, with some flying as far south as the Caribbean. Populations in the Pacific Northwest and south Florida are present year-round.
Morning wing-spreading should provide a means of absorbing solar energy and passively raising their temperature to the daytime level. Field observations indicate that this behavior is associated with the intensity of sunlight and also occurs more frequently when the birds are wet than when they are dry.
Why do some birds stand around on one leg? A. Herons, hawks, geese, ducks and gulls — birds both short-legged and long-legged — are on the Audubon Society list of those that tuck up one leg under their feathers and balance on the other. The posture reduces by half the amount of heat lost from naked, unfeathered limbs.
