Wood pigeon baby found on road

Hiii

So my friend found a wood pigeon in the rode. They brought the pidgon to me as my special interest is birds (I am an autistic) can someone tell me the best corse of action.

We don't know where the nest is otherwise we would have put it back. It's a Sunday and we cannot travel anywhere as we live in a small village between Colchester and Sudbury in the uk
