TL;DR from Wikipedia: In photon upconversion, two or more incident photons of relatively low energy are absorbed and converted into one emitted photon with higher energy.
Basically photons are combined into a photon that is nearer in wavelength to visible light.
Oh 100% you're right.
I'd wager this wasn't one of their first tests (and maybe not even a test at all). Looks to me like an advertisement/publicity stunt/demonstration.
I could be easily wrong since I haven't researched this exact event, but I think it's safe to assume it's more than just a test since they have cameras out.

Turns out, it's illegal to remove them in the US:
I'll be leaving the cowbird egg in the nest, but will keep a close eye on the other eggs.
I've heard that the cowbird will retaliate if it finds its egg missing. Won't that happen?
Well dang...
Hopefully the Robin babies do alright.
Is that for real? How would there be two species of eggs together? Is it common?
Found these six robin eggs in the hanging fern on our front porch. Walked outside to pick up a package and saw the bird fly out of the plant. The main picture was taken on the 8th.
Here's a picture of them from today. All six eggs are still there, but they have not hatched yet:
To be fair, this project looks to be from 2020, two years before Twitter was sold off.
