Adult Peregrine Falcons are primarily colored blue-gray with lighter rumps, which is a key characteristic of their plumage. This coloration helps them blend into various environments, providing them with effective camouflage while hunting. The blue-gray feathers are most prominent on their upperparts, while the lighter rumps stand out as a distinguishing feature when they are in flight, aiding in recognition among birdwatchers and falconers.

The specific hues assist in their identification, as they are a stark contrast to the more vibrant colors found in other raptor species. Such plumage not only plays a role in their hunting strategy but also in their interactions with potential mates, as well-defined coloration can signal health and genetic fitness during breeding season. This coloration is part of what makes the Peregrine Falcon one of the most recognized and admired birds of prey in the world.
