For perching birds ( most songbirds) its due to a tendon, if they put they put pressure (land on perch) on the tendon tightens and the toes automaticaly grasp the branch so no need to worry about falling off during sleep.

They only doze when they're on the perch. If they fell asleep deeply they'd thrash about while dreaming of flying and fall off. Birds only sleep really deeply on the nest.

No idea, attempt asking a reliable avian vet about that. contained in the advise time, sounds stupid, yet placed a towel or perhaps an previous small pillow(one which will be washed actual) in there previously mattress time to cushion his fall. also, if those fish tanks have fish in them, you truly might want to turn the lights off at evening. Fish do favor "evening time" besides. Get yet another evening mild for the poultry to make up for the fish tank lights.

Because their relaxed state is with claws round a perch. It takes energy for them to unclench them.

It's called the perching reflex, it is instinctive to all birds.

like some other animals, they can lock their knees while sleeping so the can stand and sleep, even on a perch.

This isnt always true, my uncles parrot fell of her perch when she was asleep and broke her neck, and it killed her. this usualy happens when they are startled or jump when they sleep. Otherwise its due to a natural balence they have, when they dont fall lol.

Birds, like horses who sleep standing up, have special tendons that allow them to stay upright. They evolved that way.

because they have a 'locking' instinct. When they foot curls around something, the toes lock into place automatically. The bird has to make a concious effort to uncurl them and let go.

It's built in. As much time as they spend in trees it'd be a pretty bad evolutionary flaw if they couldn't.
