Shadow and KD1 shared the Big Bear eagle nest on August 13 in a scene that carried both heartbreak and unexpected hope. Shadow had not stepped onto the nest since July 23. When he finally returned three weeks later, KD1 followed him in. Then something even more remarkable happened.

The young banded eagle moved sticks around the nest while Shadow watched. Later, KD1 leaned toward him and gently preened his wing feathers.
For a nest still painfully missing Jackie, it was a quiet moment that suddenly made the future feel a little less empty.

Shadow Returns to the Big Bear Nest After Three Weeks
Shadow’s arrival alone would have made August 13 significant. Friends of Big Bear Valley reports that his previous nest visit was July 23, the same day Sandy and Luna were last seen in the habitat. With the young eagles apparently beginning their lives away from Big Bear, Shadow had little reason to spend time at the nest during the summer.
Then Jackie disappeared from the territory after becoming ill and entering wildlife rehabilitation. She died in the early morning hours of August 10 following more than three weeks of intensive medical care. Three days later, Shadow finally returned to the place where he and Jackie had raised their family.
On camera, he sometimes appeared unusually still as he stood inside the nest and looked around. It is tempting to imagine what might have been going through his mind. However, we cannot know what Shadow understands about Jackie’s absence or what those quiet pauses meant to him. We can only watch what he does.
And on this afternoon, he did not return alone.
KD1 Follows Shadow Into the Nest
KD1 was not far behind. The banded sub-adult followed Shadow back to the nest, continuing a pattern that has become increasingly difficult to ignore.
KD1 first appeared around the Big Bear habitat on August 6. As the days passed, the young eagle began spending more time around Shadow and using some of his familiar perches. Then, on August 10, KD1 visited Jackie and Shadow’s nest for the first time.
By August 13, KD1 had visited the nest several times and was still staying close to Shadow. That afternoon, Shadow glided into the nest with KD1 following shortly behind.
This time, however, KD1 did more than simply visit.
KD1 Starts Moving Shadow’s Sticks
Once inside, KD1 began investigating the nest and moving some of the sticks. Anyone who has watched Shadow for long knows that sticks are serious business in his world. Yet Shadow did not chase KD1 away. Instead, he watched.
That does not mean Shadow has handed over the decorating department or accepted KD1 as a future mate. Still, seeing another eagle manipulate nest material while Shadow remained nearby made the interaction especially interesting.
Nest work can become part of pair-bond behavior in bald eagles as breeding season approaches. The U.S. Fish and Wildlife Service has documented established pairs adding sticks and working on nests as part of their seasonal bonding behavior.
At Big Bear, though, breeding season is still ahead. It is simply too early to determine whether Shadow and KD1 are developing a pair bond. The answer may not become clearer until later in the fall or winter.
Then came a much smaller gesture.
It may have been the most memorable moment of the visit.
KD1 Gently Preens Shadow
While the two eagles stood together, KD1 reached toward Shadow and briefly preened his wing feathers. Shadow allowed it. The contact lasted only a short time, but it looked remarkably gentle.
In birds, this behavior is known as allopreening, when one bird preens another. Research across bird species has found an association between allopreening and strong or stable social pair bonds. However, one brief interaction cannot establish that two birds have formed a pair.
That distinction matters here. KD1 preening Shadow is intriguing. It is not proof that KD1 is Shadow’s new mate. For now, it is another small piece of a much larger story that is only beginning to unfold.
Is Shadow Ready to Move On After Jackie?
That may be the question hanging over the Big Bear nest right now. The answer is that nobody knows. Bald eagles commonly form long-term pair bonds. However, when one member of a bald eagle pair dies, the surviving eagle can eventually accept another mate.
Whether Shadow is beginning that process with KD1 is impossible to say after only a few days. There is another important point. A future mate would not replace Jackie. Jackie’s years with Shadow, the eaglets they raised, their nest-building battles, their quiet moments together and the enormous following their family created are already part of the history of this nest.
Another eagle would bring another personality and another relationship with Shadow. It would be a new chapter, not a rewritten one. That may be why watching Shadow and KD1 together feels so complicated right now. Jackie can be deeply missed while it still feels comforting to see Shadow with company. Both can be true.
Is KD1 a Female Bald Eagle?
KD1’s sex has not officially been confirmed. The eagle hatched in Southern California in March 2022 and is now about 4½ years old. DNA testing was not performed when KD1 was banded. However, KD1 appears larger than Shadow. Female bald eagles are generally larger than males, so the size difference has raised the possibility that KD1 is female.
This remains an observation rather than a confirmed identification. For that reason, it is best to avoid declaring KD1 female as fact for now.
Then Shadow Leaves, and KD1 Follows Again
The interaction did not end when Shadow left the nest. Shadow eventually flew toward the Twin Pines. KD1 followed. That repeated closeness may ultimately prove more interesting than any single moment inside the nest.
KD1 has now appeared around Shadow repeatedly, joined him at familiar perches, visited the nest several times and followed him from place to place. Shadow, meanwhile, has continued allowing the young eagle nearby.
Perhaps this develops into nothing more than a temporary association during the non-breeding season. Perhaps KD1 eventually moves on. Or perhaps, when autumn arrives and bald eagle breeding behavior begins to strengthen, these quiet August encounters will look very different in hindsight. Right now, nobody gets to write that ending.
Jackie Is Still Part of the Big Bear Story
Only days have passed since Jackie died. For people who watched her for years, seeing another eagle beside Shadow can understandably feel startlingly fast. Wildlife does not follow the emotional calendar of the people watching through the cameras.
Shadow will continue responding to his environment and instincts in ways that make sense for a wild bald eagle. So will KD1. Nothing that happens next can take away the years Jackie spent at this nest or the family she and Shadow created there.
But the nest did not disappear when Jackie died. Shadow is still here. And now another eagle keeps showing up beside him. On August 13, Shadow and KD1 stood together in the Big Bear nest. KD1 moved his sticks. She gently preened his feathers. Then, when Shadow left, she followed him.
It may become the beginning of something.
It may not.
But after so much loss, the sight of Shadow returning home with another eagle quietly beside him offered something the Big Bear nest has desperately needed.
A reason to keep watching.

FAQ
Are Shadow and KD1 mates now?
No. Shadow and KD1 have been spending increasing amounts of time together, but Friends of Big Bear Valley says it is too early to determine whether a new pair bond is forming. Their behavior during the fall and winter breeding period may provide more clues.
Did KD1 preen Shadow at the Big Bear nest?
Yes. During their August 13 nest visit, KD1 briefly reached over and preened Shadow’s wing feathers. Allopreening can be associated with social bonding in birds, but this single interaction does not prove they are becoming mates.
Is KD1 female?
KD1’s sex has not been confirmed through DNA testing. However, KD1 appears larger than Shadow, which suggests the eagle could be female because female bald eagles are typically larger than males.
When did Shadow last visit the Big Bear eagle nest?
Before returning on August 13, Shadow’s previous documented nest visit was July 23, when Sandy and Luna were last seen in the Big Bear habitat.
Could Shadow take another mate after Jackie?
Yes. Bald eagles often maintain long-term pair bonds, but a surviving bald eagle can accept another mate after losing its partner. Whether KD1 will become that eagle for Shadow remains unknown.
