Migration. May be permanent resident in southern Florida, but in most of United States range it is far less common in winter than in summer.

Why is it called yellow crowned night heron?
The long legs are yellow and turn coral, pink or red during courtship. The most characteristic part of the yellow-crowned night heron is the head: black and glossy, with white cheeks and a pale yellow crown going from the bill, between the eyes and to the back of the head, giving the bird its common name.
The genus name Nycticorax derives from the Greek for “night raven” and refers to the largely nocturnal feeding habits of this group of birds, and the croaking crow-like call of the best known species, the black-crowned night heron.
How to Get Rid of a Heron with a Motion-Activated Sprinkler. But if you really want to keep herons out of a garden or pond and stop them from feasting on your fish, try using a motion-activated sprinkler device such as Critter Ridder® Motion Activated Animal Repellent Sprinkler to repel the birds.
Black-crowned Night-Herons are opportunists feeders that eat many kinds of terrestrial, freshwater, and marine animals. Their diet includes leeches, earthworms, insects, crayfish, clams, mussels, fish, amphibians, lizards, snakes, turtles, rodents, birds, and eggs.
They are affected by a number of threats across their annual cycle, including wetland loss and water pollution. In the U.S., more than 50 percent of the wetland habitat that these birds rely on has been lost, mostly due to human development and agriculture.
Black-crowned Night Herons are strikingly attractive birds and are important members of their ecosystems because they help to control fish populations.
The black-crowned night heron is 23-28 inches tall. It has a wingspan of almost four feet. It is a medium-sized heron with a stocky body and short legs and neck.
“What eats me”
Black-crowned night herons – particularly young birds — may be taken by birds of prey such as hawks and eagles, and eggs and nestlings are vulnerable to a variety of nest predators such as raccoons.
Diet. Mostly fish. Diet quite variable; mostly fish, but also squid, crustaceans, aquatic insects, frogs, snakes, clams, mussels, rodents, carrion.
Also, “fascinating are bats preying on other bats, for instance Nycteris grandis in Africa, Macroderma gigas in Australia, and Vampyrum spectrum in the Neotropics.” Jakob also notes that other animals such as amphibians, insects, and yes, herons and egrets, have also been seen preying on these flying mammals.
Herons rest during the day by folding up their neck and sitting quietly in a sheltered spot. At night, many herons demonstrate a bird behavior that might surprise you: sleeping in trees. Many herons sleep in trees at night, to get them off the ground where land dwelling predators might catch them off guard.
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.
Herons fish mostly at dawn and dusk so they are rarely noticed. Even ponds with ornamental fish can attract herons, which is something to keep in mind if you would prefer not to receive any visits!
Decoys may prevent a heron from swooping down in the first place, but herons have been known to ignore these motionless animal impersonators and accept them for exactly what they are: statues.
Do not let your Koi or gold fish appear on the specials board! Herons are capable of eating copious amounts of fish, on a daily basis. An adult heron can easily consume up to 1lb of fish per day. This equates to roughly 3 x 7 inch long Koi that cost about $70 each.
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.
Their name makes them sound like a team of minor-league Marvel superheroes: The Night-Herons! They sit motionless in the shadows, not making a sound.
Great blue herons are able to hunt day and night, thanks to their excellent vision. It's sometimes said that they need bright moonlight for nocturnal hunting, but the high density of rod type receptors in their eyes give them excellent night vision. They can and do hunt successfully on moonless nights.
