American kestrels are migratory birds, and their migration patterns vary depending on their geographic location. In general, American kestrels that breed in the northern parts of their range migrate south for the winter, while those that breed in the southern parts of their range may only migrate short distances or not migrate at all.
American kestrels typically begin their spring migration in late February or early March, and they arrive on their breeding grounds in mid-April to early May. They typically begin their fall migration in late September or early October, and they arrive on their wintering grounds in mid-October to early November.
American kestrels migrate during the day, and they typically fly at altitudes of up to 2,000 feet. They have a wingspan of 22-26 inches, and they can fly at speeds of up to 25 miles per hour.
American kestrels are carnivorous birds, and they primarily eat small mammals, such as mice, voles, and shrews. They also eat birds, reptiles, and insects.
American kestrels are a beautiful and fascinating bird of prey. They are an important part of the North American ecosystem, and they play a role in controlling the populations of small mammals and insects.
