Night Heron Nests

The male night heron searches for twigs and sticks on the ground. When he finds a sturdy stick or twig, he gives it to the female of the pair who uses it to build the nest. The nest may be in a tree or on the ground in a sheltered area among a gathering of tall weeds.

The nest of a night heron measures from 12 to 18 inches in width and can be from eight to 12 inches tall. The structure has sticks and twigs of different sizes sticking out at every angle. But there’s ample space to accommodate three to eight two-inch-long eggs.

Scientific Name

Nycticorax nycticorax is the scientific name of the black-crowned night heron. The Latin word nycticorax means night raven. Though the night heron is not related to the night raven, there are some reasons behind the scientific name. The night heron is active at night and this bird’s call sounds similar to a raven’s call: “Croak, croak!”

It’s in the Ardeidae family and in the Aves class.

The black-crowned night heron also called the black-capped night heron, is one species of this bird. Others include:

  • Yellow-crowned night heron or yellow-crested heron (Nyctanassa violacea)
  • Nankeen night heron (Nycticorax caledonicus)

Appearance and Behavior

The various types of night herons differ a bit in appearance. The black-crowned night heron or black-capped night heron has white feathers on its breast along with greyish black wings. It has a black crown or cap of feathers atop its head. Alternatively, a yellow-crowned night heron has gray, almost purple feathers on its breast and wings. This bird has a stripe of white feathers near each eye and yellow feathers that stick up on its head. Its sometimes called the yellow-crested night heron because its long crest of yellow feathers extends over the back of its head.

Juvenile black-crowned or black-capped night herons have brown feathers with some white spots mixed in. Its beak is not yet deep black like an adult night heron’s beak.

An adult night heron has a long, pointed beak it uses to grasp fish, insects, and other prey. It walks on its long, thin legs through the water and grasps tree branches with its four sharp claws.

This bird is 23 to 26 inches long and weighs 26 to 36 ounces. Its wingspan is 45 to 47 inches.

Along with using its long, pointed beak to find food, the night heron uses it to defend itself. Luckily, its habitat high up in the treetops helps it to avoid many predators.

Migration and Timing

While some types of night herons live in the same area year-round others migrate to warmer places for the winter months. As an example, in September or October the black-crowned night herons living in Massachusetts fly south down the coastline to Florida. Black-crowned night herons living in Alberta, Canada fly south to spend the winter in Mexico. Some of these birds have a migration route running beside the Mississippi River system.


All types of night herons including black-crowned and yellow-crested varieties are carnivores. They hunt for food at night by standing perfectly still in or near the water until a fish swims close by. Within seconds, the bird grabs it and swallows it!

What does a night heron eat?

Frogs, fish, and insects are all prey in the diet of night herons.

Predators and Threats

What eats night herons?

Adult night herons spend time high up in the trees which makes them less vulnerable to predators. But, they do have some including owls and foxes.

Hatchling and juvenile night herons are more likely to be preyed upon by foxes and owls because they are smaller and not as strong as adult birds. Furthermore, raccoons and snakes have been known to steal night heron eggs out of a nest to eat them.

Habitat destruction is another threat to adult night herons. Drainage of the wetlands has affected the population of this bird. Their population has also been affected by pesticides in the insects they eat.

Steps have been taken to help night herons including setting up protected areas where they can breed. The IUCN Red List of Threatened Species categorizes it as Least Concern, but with decreasing numbers.

Reproduction, Babies, and Lifespan

Male and female night herons are monogamous and both parents take care of the eggs. Female night herons lay three to eight eggs in late spring or early summer. After 21 or 22 days, the eggs hatch. The chicks leave the nest at just two weeks old. The chicks grow quickly into juvenile birds. They remain in the nesting area until they can live independently at six to seven weeks old. These birds are sexually mature at the age of two or three years.

The lifespan of a night heron is 10 to 15 years.


The worldwide population of the night heron is 570,000 to 3,730,000 birds. Though their numbers are reportedly decreasing, the night heron is of Least Concern to conservationists.
