We're also his best friend. Wild raccoons can live up to 16 years, and resulting population explosions can result in damage to yards and rambunctious fighting. They live in family groups, have at least 23 distinct caws to communicate, and cooperate. They generally mate for life, serve as lookouts for one another as they feed, and beckon each other to a free dinner. In England, a gravestone is sometimes called a ravenstone.
Ravens are very similar to crows, but about one-third bigger and inhabitants of wilderness.
There are 42 separate species of these two birds around the world. Crows can mimic human speech as effectively as a parrot, often return to the same tree to nest for year after year, and believe in family values. Several generations can help in building a nest, feeding an incubating female and chasing away predators. Highly analytical, a crow can be observed reasoning as it figures out a way to break into a package or get plunder into its beak. One of the world's oldest surviving mammals, this pouched marsupial has survived unchanged for 70 million years.
