Baby Blackbird on the ground

[Bananalanacake]

This was the best subject/topic I could find, I know a blackbird isn't a pet.

This morning when we opened the door to go to school a bird flew away from near the door and DD saw there was a baby bird on the ground. it is in a gap of about 30cms between 2 walls, one of them being the steps from the door. The bird is on a pile of dead leaves, it moves and chirps but I'm guessing it's too young to fly. I see the mum regularly going to the spot where it is. My worry is what if a cat or animal gets to it, we don't have a cat but there are plenty around. I don't want to touch it in case the mum rejects it.
Does anyone have any idea how it got there and what is the best thing to do.

Rspb generally say to leave it
It might be vulnerable there, but the parent knows it's there and it's probably going to be distressing to both of them to interfere

Baby blackbirds leave the nest quite a few days before they can fly. They then spend their time flopping around under shrubs and bushes while their parents feed them and utter loud cries of alarm. Some get picked off by cats, foxes and other birds (magpies... horrible things). This is the way of life. Given that a breeding pair of blackbirds usually have about eight babies a year they can't all survive, or the skies would be black with them.

That's interesting, so it's normal for them to live on the ground, just seen it hopping around and now it's under a bush, hope it's ok until it learns to fly.
