Crows

Corvus corax, the common raven, is a large passerine bird of the family Corvidae, along with rooks, jackdaws, and magpies. Native to the Northern Hemisphere, it inhabits mountains, forests, and grasslands. Ravens are the largest members of the Corvidae family, with a wingspan of up to 120 centimeters (47 inches) and a weight of up to 2.1 kilograms (4.6 pounds).
In mythology and folklore, ravens are often depicted as tricksters or messengers, and are associated with both death and prophecy. In European folklore, they are often considered to be harbingers of bad news or doom, while in some Native American cultures they are seen as symbols of wisdom and intelligence.
Ravens are highly intelligent birds, and are known for their ability to solve problems and use tools. They have been known to use sticks to retrieve food from out of reach, and have even been observed using twigs to catch insects.
Ravens are also very social animals, and live in large, extended families. They will often share food and defend their territory from other predators. Ravens are also known for their complex vocalizations, and can communicate with each other over long distances.
In the wild, ravens typically live for 10-15 years, although some individuals have been known to live for up to 20 years or more. Ravens are not endangered, but their populations are declining in some areas due to habitat loss and hunting.
Ravens are fascinating creatures with a long history of interaction with humans. Their intelligence, social behavior, and adaptability make them one of the most remarkable birds in the world.
