Doubling down on a niche that works often outperforms fitting into many niches where you kinda suck at all of them.

masturbation was killing them

One possible reason is that using your front paws to climb and grasp will ruin the feathers on them by causing them to rub and drag against things, and those feathers happen to be vital for flight.
(notice also how legs and beak are basically the only parts of birds that aren't covered in feathers, and many vultures further dropped feathers on their entire face or head for obvious reasons)

who needs hands when you have wings. With wings, you can go anywhere you want.

When wings started to form from a central couple where a female came from another world and passed the information onto this group from love.

New offspring tested themselves on top of a cliff by extending their wings, exercising them before jumping off. Many didn't survive flying away before hitting the rocks below because DNA changes take a more direct route through family lineage.

There's a special saying in us: we would throw you off the cliff if you didn't take. Some could push others off the cliff to their deaths because they are a burden on the changes if they had offspring.

I know this because I propelled continually backwards in time in a quantum jump through people, then animals, for greater knowledge and help.

I meant the reason was for survival. The environment was changing.

Lol.
