Apparently, sparrows make surprisingly good pets

When I see cases where people pick up and raise injured sparrows,
it turns out they actually live quite well with humans.
In the case of crow-tit (Baepsae), they must live in flocks, so it's hard for them to live with humans,
but sparrows can live well even as loners, they recognize their owners, and even act cute.
The downside is that they are so small that accidental crushing is a common risk.
