 Most accipitrids have distinct plumages in their immature stage, which presumably serves as a visual cue to others of their species and may allow them to avoid territorial fights.Shortly after attaining mature plumages, pairs form with a male typically displaying, often in flight but sometimes vocally, to win over a female.Many accipitrids breed with the same mate for several years or for life, although this is not the case for all species and, if a mate dies, the widowed bird will typically try to find another mate the following breeding season.
