Descendants of Crows
Different species of crows had different breeding conditions. For example, crossbreeding between northwest crows and short-beaked crows could produce offspring. These offspring had the ability to reproduce and had the tendency to become a new species. The breeding of the island crows began from March to July every year. They built nests on trees, laying 3 - 9 eggs in each nest. The eggs were hatched by the female bird. The incubation period was 16 - 18 days. After the young birds hatched, they were raised by both parents. After 29 - 30 days, they flew out of the nest to look for food. The California branch of the raven and the entire northern branch of the raven were genetically mixed to produce fertile offspring, causing the purebred California raven to become extinct and creating a new hybrid species of common raven.
