The family Corvidae consists of medium to large passerine birds commonly known as crows, ravens, magpies, jays, and nutcrackers. Members of this family are found worldwide, except in the most extreme polar and desert regions, and are highly adaptable to diverse habitats. Corvids are renowned for their intelligence, problem-solving abilities, and complex social behaviors, including cooperative breeding, tool use, and sophisticated communication. They typically have strong, stout bills, robust bodies, and strong feet, with plumage often in shades of black, gray, or striking patterns of white and blue. Omnivorous in diet, corvids feed on insects, small animals, seeds, fruits, and human food waste, making them versatile foragers. Their ecological roles include seed dispersal, carrion cleanup, and influencing prey populations, highlighting their importance in ecosystems.
