Smithsonian Magazine had a related article
in its February issue, which I just got around to reading yesterday. It was about pair bonding in prairie voles, which have similar stats on monogamishness to those of the birds in the video.
Not so for meadow voles, which are nearly identical but don't pair up for life. Researchers took a prairie vole gene and injected it into a virus, which they introduced into brains of meadow voles.
The point? To see whether the alien DNA would alter the meadow vole’s behavior. It did: As the animals grew up, they began exhibiting pair-bonding behaviors. “We transformed a meadow vole into a prairie vole, behaviorally,” he says.
No word on how this might be applied to humans, but I worry it's only a matter of time.
