Not an accurate depiction of birds...after the helpless phase birds become fledglings where they leave the nest but are still dependent on their parents for food. Social structures vary a lot by species but many remain with parents for quite some time.
I mean, some bird species have mothers that essentially drop their fledglings to predators to distract from themselves (and their insecurities), or just simply don't feel bothered to actually help raise them to maturity.
True. Some just lay their eggs in someone else's nest and go "good luck!" It's hard to characterize the behavior universally across an entire class. But I wouldn't say what's depicted here is very typical.
It's also, in my experience, very rare for passeriformes to run Arch Linux.
