You know, for a trope that often ends up as a sight gag in kids movies, locking a character in an oversized birdcage is a pretty horrible thing to do. Especially if it’s hanging from the ceiling.
It’s a cage, so the whumpee is trapped without being at all protected. At least in a dark cell, no one can poke anything through the bars.
Extremely cramped conditions. Even if the cage is scaled up for a human (sized) whumpee, they probably won’t be able to stand, stretch, or lie down. If the base isn’t solid, then even sitting will be uncomfortable.
The whumpee is on display where everyone can see them. They aren’t just trapped, but trapped like an exotic pet.
Whatever bird symbolism your heart desires.
…………
And specifically for a hanging birdcage:
The cage will rattle around whenever the whumpee tries to move. If they try to shake the bars, they’ll end up swinging. That’s sure to draw everyone’s attention.
Or the whumper can shake the cage. Leave the whumpee with bar-shaped bruises.
If it’s really high up, then there isn’t any concern that the whumpee will squeeze through the bars or pick the lock. What are they going to do? Jump 20 feet to the floor and break a leg?
They’ll need to be winched up and down every day unless you completely handwave biology. What’s the process for shoving them back in?
Slowly lower it into water so the whumpee has to cling to the top to breathe.
