By protecting their natural habitat and reducing the numbers of predators peacocks should be able to reproduce more young
they kill them and destroy their habitat
The purpose of a peacocks feathery display is to entice a receptive female (peahen) to mate. So, you could say that the colours do help in reproduction.
what other living help peacocks to survive
To help use humans help animals and plants to reproduce and survive better.
Not without help.. ;-)
they peck the animals brains out
No other animals don't help reproduce .
Natural instincts are what help all animals to survive. Without them, we wouldn't know or feel the need to eat, reproduce, learn, evolve and improve our species.
It depends on what you think is special. Peacocks have cool intricately colored feathers. Horses can help humans out a lot. You can ride horses, you can watch peacocks. I guess I would choose the horse as more special, because you could develop a closer relationship with it than you could with a bird... but both of them are special. Just in different ways.
