Ravens are large songbirds, and people believe that crows are smart, savvy, and gifted. Ravens are found throughout most of the Northern Hemisphere. They are mentioned in folklore and mythology from Scandinavia and ancient Ireland and Wales to Siberia and the northwest coast of North America. Large body size and dense plumage protects against cold winters. The huge beak is strong enough to split solid matter.
Crows are sociable, birds live in pairs until the age of one or two years, have not yet got a partner. They spend the night, having gathered in rather large groups, and form flocks to make it easier to get food together.
Hoodie
With the exception of the wings, tail and head and part of the neck, which are black, the rest of the body is covered with ash gray feathers, and color is determined by age and seasonal factors. On the throat of the raven there is a black rounded spot, like a bib.
Black Crow
One of the smartest birds, rather fearless, but careful with people. They meet singly or in pairs, form a few flocks. They fly to people for food, and are careful at first. When they find out that it is safe, they return to take advantage of what the person has to offer.
Large-billed crow
A widespread species of the Asian crow. It adapts easily and survives on a wide variety of food sources, which increases the ability to colonize new areas, which is why these crows are considered a nuisance, like locusts, especially on the islands.
Shiny Raven
It is a small bird with a long neck and a relatively large beak. Head length 40 cm, weight – from 245 to 370 grams. The crow has a glossy black color, with the exception of a distinct smoky gray “collar” from the crown to the mantle and chest.
White-billed raven
It is a short and stocky forest bird (40–41 cm long) with a short, square tail and a relatively large head. The characteristic curved ivory beak. The dark nasal feathers, although not dense, are quite noticeable against the background of the pale beak.
Collared raven
A beautiful bird with shiny black plumage, except for the white back of the neck, upper back (mantle) and a wide band around the lower chest. Beak, black paws. Sometimes it flies in a “lazy” way, the legs hang down below the body.
Piebald crow
This crow adapts to its habitat, in cities it finds food in trash cans. The head, neck and upper chest are black with a blue-violet sheen. These black pieces contrast with the white collar on the upper robe that extends to the lower chest and sides of the body.
Novokoledonsky raven
According to research, crows twist twigs into hooks and make other tools. Smart birds pass on their experience of successful problem solving to future generations, which is a distinctive feature of this species. The plumage, beak and feet are shiny black.
Antillean raven
The white bases of the neck feathers and the purple sheen on the upper parts of the body are barely visible from the ground. But a relatively long beak with orange-red irises is clearly visible from afar. The crow produces a wide range of laughing, clicking, gurgling and screaming sounds.
Australian crow
Australian crows are black with white eyes. Feathers on the throat are longer than in other species, and the bird seeks to stretch them out when singing, the head and body remain at this time in a horizontal position, the beak does not rise up, as well as there are no flapping of the wings.
Bronze Crow (Vulture Crow)
A large 8–9 cm long beak is flattened laterally and deeply curved in profile, which gives the bird a distinctive appearance. The bill is black with a white tip and has deep nasal grooves with light nasal bristle feathers. Feathers are short on the head, throat and neck.
White-necked crow
The plumage is black with a purplish-blue sheen in good light. This is one of the smallest species. The base of the feathers on the neck is snow-white (visible only in strong winds). The beak and legs are black. Crows feed on grains, insects, invertebrates, reptiles, carrion, eggs and chicks.
Bristly crow
The raven is completely black, including the beak and legs, and the plumage has a bright blue sheen in good light. Plumage over time in older individuals acquires a copper-brown color. The base of the feathers on the upper part of the neck is white and is only visible in strong gusts of wind.
South australian crow
An adult is 48-50 cm long, with black plumage, beak and paws, feathers have a gray base. This species often forms large flocks that move across territories in search of food. They nest in colonies of up to 15 pairs at a distance of several meters from each other.
Bangai crow
The total number is estimated at about 500 mature individuals living in the mountainous forests of Indonesia at an altitude of over 500 m. The decline in crow numbers is believed to be due to habitat loss and degradation from agriculture and tourism.
Conclusion
Crows are smart, they find a way out of unusual situations. The birds ignore the noise effects, but fly to the place of the shot, knowing that the pieces of prey left by the hunter are somewhere nearby. Sometimes they work in pairs, make forays on colonies of seabirds: one crow distracts a bird incubating eggs, and the other waits to grab an abandoned egg or chick. We saw a flock of crows waiting for the sheep to give birth and then attacking the newborn lambs.
Ravens open bags, backpacks, and refrigerator latches to grab food. In captivity, they learned an impressive number of “tricks” and solved riddles that even some people cannot cope with.
