The wingspan of the gray heron is from 155 to 195 cm, the standing height is 100 cm. Weight is from 1 to 2 kg.

As their name suggests, their plumage is steel gray in color.

The neck and head are white, with a bluish-black stripe running from the eyes to the back of the head, topped with a large crest. Their head is equipped with a pink-yellow long and straight beak, and the iris is yellow. The beak is ⅔ of the length of the skull. There are rows of vertical black lines on the neck. The legs are long and brown.

It is yellow most of the year, but during the short mating season it turns orange.

Their flight is very characteristic, the neck is bent and the head is pulled towards the body.

This feature distinguishes herons from cranes and storks.

These are carnivores, most often feeding on what they find nearby or directly in the body of water.

Their diet consists of invertebrates, fish, amphibians, snakes, small birds and mammals. It happens that a heron hunts small ducks or other birds with a body size of up to 25 cm.

They swallow small prey whole, and tear larger prey into pieces.

Large prey is carried ashore, where the heron overpowers it and eats it piece by piece, pecking and tearing out pieces of meat. In the case of small birds and mammals, herons can grab them with their beaks and plunge them under water to drown the victim.

11

Herons usually search for prey in the water, but sometimes on land.

They usually stand still and wait until the prey gets close enough. Apparently, they are most effective when hunting on moonlit, cloudless nights.
12

Their breeding season begins at the end of February and lasts until the beginning of June.

At first, males look for a convenient place to build a nest, most often in the branches of tall trees, but sometimes on the ground. They are built from any available material, most often from branches and grass. After the nest is built, the period of calling females begins, and when they are nearby, the males begin to flap and spread their wings and raise their beaks vertically upward. The final stage of courtship is when the male and female touch each other's beaks and stroke each other.

After breeding is completed, the nest is preserved and can be used by other pairs in subsequent years.

Herons often expand old nests by adding new materials on top of the previous structure.

Young herons become chicks approximately 7-8 weeks after hatching, although they are not yet fully independent. They gain full independence at about 10 weeks of age.

Only about 30% of the juveniles survive their first year, most of them falling prey to predators. Due to their size, adults do not have many natural enemies. The greatest threat is from foxes and people.

However, the record holder lived to be 23 years old.
