On the Big Bear eagle camera, the clue is small enough to miss: a lavender band circling one leg of the young bald eagle now appearing around Shadow, carrying the white code KD1. As viewers absorbed Jackie’s death on August 10, that band turned an unfamiliar visitor into a bird with a history.

KD1 hatched in March 2022 in the Prado Basin in Riverside County, where Orange County Water District biologists banded the eaglet and a sibling in late April. Friends of Big Bear Valley officially named the eagle Kaydee on August 19. The identity is settled. The bird’s sex, and the meaning of Kaydee’s repeated time near Shadow, are not.

The band matters because the years after a young eagle leaves its natal area can be difficult for observers to reconstruct. Kaydee’s lavender identifier, paired with a metal band on the other leg, allowed people in Big Bear to connect the bird with the nestling handled four years earlier in the Prado Basin. The bands identify Kaydee when someone sees and reports them. They do not provide a continuous record of the bird’s travels.

Friends of Big Bear Valley first recorded the banded subadult on its cameras on August 6. Kaydee visited Jackie and Shadow’s nest on August 10, then arrived close behind Shadow when he returned to the nest on August 13. The following day, the two spent several hours in the same Twin Pines perch tree. By August 19, cameras had documented them vocalizing, using the same roost area and leaving a perch within seconds of one another.

Those encounters came after Big Bear’s eaglets Sandy and Luna had left the habitat and the nesting season had quieted. That timing makes the sightings important, but it does not make them courtship. Outside the breeding season, bald eagles may use the same productive habitat without forming a pair.

What Kaydee’s presence can and cannot tell us

Kaydee appears larger than Shadow. Because female bald eagles are generally larger than males, Friends of Big Bear Valley says it is leaning female. Yet no DNA sex test was conducted when KD1 was banded, and size judged through distant cameras can be affected by posture, angle and perspective. The careful conclusion is that Kaydee may be female, not that the question has been answered.

Age adds another layer. At roughly 4½ years old, Kaydee is approaching the stage when bald eagles usually reach adult plumage and sexual maturity. The National Park Service places that transition at about five to six years. A nearly white head and tail can signal that maturation is close, but plumage alone cannot confirm sex, breeding readiness or intent.

The same restraint applies to Kaydee’s relationship with Shadow. Repeated perching, vocalizing and nest visits show that the two eagles are tolerating one another at close range. They do not prove a pair bond. Bald eagles can accept a new partner after a mate dies or disappears, but the evidence develops over time through sustained territory use, courtship and coordinated nest work.

That uncertainty is part of what makes the next few months worth watching. Kaydee may remain in Big Bear as breeding season approaches. The eagle may continue wandering, as younger bald eagles often do. Shadow may stay near the familiar nest, shift elsewhere in the valley or eventually bond with Kaydee or another bird. None of those outcomes can be read from a single perch.

For people who followed Jackie for years, the impulse to place Kaydee immediately into the empty space beside Shadow is understandable. It is also premature. A new bird does not erase Jackie’s history, and it does not arrive with a predetermined role.

For now, the lavender band provides the clearest answer available. Kaydee is a known 2022 Prado Basin eagle, alive and using the Big Bear habitat four years later. The name is confirmed. The bird’s sex, destination and future with Shadow still belong to time.
