Introduction

Southeast is…).

Description

This species is easily recognized beak (Dimya, in the strict sense, is an external anatomical structure that allows food intake and…).

Its size (length between 46 and 59 cm) and body proportions vary by region.
More than enough north (North is the cardinal point against south.) of Japan, the Kuril Islands and the peninsulaIsland (An island is a piece of land surrounded by water, be it a river or…) of Keep it (Sakhalin (Russian: Сахалин; az…)slightly larger than a carrion crow (Crown of Corvus), while in India Southwest (Southwest is the half direction between the south and west cardinal points. The…) is significantly smaller than its range.
It still has a very large beak with an arched upper part.
In general, there are more or less dark and duller gray hairs on the back of the head, on the face the neck (The neck is the region of the body between the head and the rest of the body…), shoulders and lower body. Its wings, tail, face and throat are a deeper, glossy black.
In Indian varieties, density (The density or relative density of a body is equal to the ratio of its density ….) gray changes; almost black to lighter gray.

Ecology and behavior

Like all corvids, it is omnivorous and versatile in its diet. Feeds on a wide variety of food (living or dead, plant or animal) on the ground or in trees, but willingly pretends to be scavengers and scavengers. He to play (The cheek is the part of the face that covers the oral cavity…) plays an important role in the elimination of corpses in the ecosystem.
It is known to kill more domestic chickens than any other corvid species. In Japan, wild crows are considered a plague because they have learned to open garbage bags (which sometimes use their strings). closure (The term closure refers to:) integrating them into their nests).

Distribution and habitat

Its range extends from the coast of North Asia to Afghanistan and eastern Iran to large areasthe west (West is the cardinal point, opposite east. This direction…) and the horse south (South is the cardinal point against north.) From India southeast to Peninsular Malaysia. The Philippines (The Republic of the Philippines is a country consisting of an archipelago) it also has a regional form. Lives mainly in forests, parks and gardens, but less frequently in open areas and farmland in less wooded areas, especially when not competing with other corvid species (especially the carrion crow);

Perching

It is abundant when resting and can form large groups in nesting burrows at night, even The season (A season is a period of the year that observes the relative stability of the climate and…) reproduction, because the young do not reproduce the first time year (A year is a unit of time that represents the time between two occurrences of a related event…). [3] During the day, mature couples are busy defending their jobs territory (The concept of territory is becoming more and more important in geography and especially…)but at night they join large groups.
Hierarchy phenomena based on the recognition of dominant individuals appear. [5].

Reproduction

the nest (A nest generally designates a structure built by birds…) usually a platform of tangled branches built into it height (Height has several meanings depending on the subject area.) one tree (A tree is a land plant that can self-grow at altitude…) with a preference for large conifers such as fir tree (Firs are conifers of the genus Abies…) or candle (Pin means 🙂 where they are.
lays 3 to 5, in exceptional cases 6 or 7 eggs; eggs are mottled blue-green and streaked with dull red-brown, sepia, gray. Eggs are incubated for 17-19 days.
At 35, young people become relatively independent day (A day or day is the interval between sunrise and sunset; it…).
In India, various species (or subspecies?) breed in the plains from March to May, but some lay eggs even as late as mid-December. The nest is sometimes made of woolen threads, pieces of cloth, fibers (Fibers are plant or animal, filamentous elementary formations, se…) plants etc materials (A material is a material of natural or artificial origin formed by man…) similar. Some nests have been found to consist partially or only of ropes [3].
