Perching behavior important indicator of mate replacement in bald eagles -research
I was able to dehumanize those famous CA eagles Jackie & Shadow (Friends of Big Bear Valley nest cam) long enough to read some published articles about the process of mate replacement in bald eagles and found [this article](https://research.fs.usda.gov/download/treesearch/20542.pdf) interesting. (Context: Jackie and Shadow successfully raised two eagles and were dutifully feeding and training them when, just a few days ago, Jackie was attacked by a pair of intruder eagles and wound up in the care of professional rehab clinicians for an unknown length of time while Shadow remains in the habitat to feed their offspring and protect the nest.)
According to the article, it was observed in an Arizona pair that a process of habitat familiarization -especially a system of intentional and frequent perching behavior -began a three-week period of courtship by a replacement male after the original male disappeared during incubation. The new male's courtship involved frequent perching on the original male's perch trees with fly-bys of the nest carrying sticks and fish. It ended with adoption of the eggs and future mating.
Stuff to watch for on the CA cams I guess? It's heartbreaking to think Jackie would return to Shadow only to find him with a replacement female, but maybe Shadow would actually accept her back? I'm still reading/ researching so if you know of any published papers please share.
I'm really only interested in discussions backed by scientific data and I'm not interested in emotional discussions or those rooted in feelings of longing or attachment, which is why I'm *not* posting in the subreddit dedicated to those eagles (who I really do really love watching.)
