When do Red-tailed Hawks begin to migrate south?

Red-tailed Hawks typically begin their migration south in relation to seasonal changes, particularly influenced by daylight hours and temperature shifts. The timing is closely linked to the Autumn Equinox, which occurs around September 22-23. When daylight begins to decrease significantly, this can trigger migration behaviors in many bird species, including the Red-tailed Hawk.

While other factors such as snow and food availability can impact a bird’s behavior, the primary indicator for their migration is related to the Equinox and the resulting changes in daylight. Therefore, stating that they migrate two weeks after the Equinox correctly aligns with observed behavior and natural patterns in raptor migration.
