This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Yesterday night/morning an animal buried this acorn in my 5th floor balcony flower pot
(sh.itjust.works)
Photo of flower pot with red houseleek and some grass coming out between the remnants of the Edelweiss that died a few months ago and a fresh hole with a single acorn in it.
I sure hope your balcony can hold the weight of an oak tree.
In that pot it can only become a bonsai, but I will probably rip it out before it comes to that and the animal doesn't retrieve it's food until next year, because the roots could come out through the pots bottom drain holes and cause damage.
Are there squirrels in your area?
I have seen them go up vertical house walls to raid a bird feeder on my neighbour's balcony on 4th floor...
Yeah, there are, but I have only ever seen them on and between trees, never on houses. Would be nice to have them visit during the day, when my shutters are rolled up so I can admire them.
The hole is also very small and I had blackbirds dig in the pot next to it before, so I also suspect birds. Crows are known to leave gifts and acorns are among the possible choices.
If it was a squirrel, it may come back and search it in a few months.
Wildlife cam!
Blue Jays and Sparrows will also do this and usually only at dusk or dawn.
Thanks for the info. We don't get blue jays here in EU, but lots of sparrows and the eurasian jay known locally as the Eichelhäher (Acorn Jay). The acorn seems too big for regular sparrows beaks, but not sure. If it's an eurasian jay I probably won't see them, because they are very shy here. I only ever saw them from very far, hiding on trees when I heard their warning signal.
Yes, other species of Jays would also be capable of doing this.
Thinking about it more, the EU has another more probable species: Woodpeckers.
When I lived in Spain, there were half a dozen woodpeckers who would eat acorns. I have zero doubt that a woodpecker would do this.
