Corvus brachyrhynchos pascuus
Most wild Crows live for about 7--8 years Crows are monogamous breeding birds. Mated pairs will form large families of up to 15 individuals from several breeding seasons that remain together for many years. Offspring from a previous nesting season will usually remain with the family to assist in rearing new nestlings. Crows do not reach breeding age for at least two years. Most do not leave the nest to breed for four to five years. Crows are very social, sometimes forming flocks in the millions. Inquisitive and sometimes mischievous, crows are good learners and problem-solvers, often raiding garbage cans and picking over discarded food containers. They're also aggressive and often chase away larger birds including hawks, owls and herons."American Crows are protected internationally by the Migratory Bird Treaty Act of 1918".
