A new bald eagle, identified as KD1, was seen at the Big Bear nest alongside Shadow on Thursday, raising questions about a possible bond forming between the two birds.
The sighting occurred just days after Shadow’s longtime mate, Jackie, died following a serious illness. KD1, a 4½-year-old eagle, was first spotted at the nest on August 10, hours after Jackie’s passing, and has since made multiple visits.
According to the Friends of Big Bear Valley (FOBBV), which operates the nest’s livestream, Shadow and KD1 were observed together in the nest for several minutes before flying off. The nonprofit did not confirm whether a bond was forming but noted that future interactions would provide clarity.
Identification and Background
KD1 was banded in April 2022 by the Orange County Water District in the Prado Basin, approximately 70 miles from Big Bear. The band bears the inscription “KD1” in lavender. Wildlife biologist Jenna Carpenter, who was present during the banding, suggested KD1 could be female based on its size, as female raptors are typically larger than males. However, Carpenter noted that the gender remains unconfirmed.
KD1’s parents were named Ricky and Lucy, the same names as Jackie’s former mate, though they are not the same pair. KD1 is nearing breeding age, which typically begins at five years old for bald eagles.
Nest Dynamics and Future Observations
Shadow had not visited the nest since July 23 before Thursday’s sighting. FOBBV stated that breeding season for bald eagles in the region typically begins in late fall or winter, meaning any potential pairing would not occur immediately.
Experts emphasize that further observations are needed to determine whether KD1 and Shadow will form a lasting bond. The nest’s livestream, which has gained international attention, continues to monitor their interactions.
Jackie, a well-known bald eagle, had been Shadow’s mate for years before her death on Monday. The cause of her illness was not disclosed.
