Young blackbirds (sometimes called juveniles) can be confused with thrushes or even robins, due to their speckly brown feathers. They're often a rich, reddish brown colour, especially on their breasts.
You'll often see them following their parents around, pestering for food. Baby blackbirds usually leave the nest before they can actually fly, and hop and scramble their way around trees and bushes. They can be vulnerable from predators at this time, but you should resist the temptation to make a 'rescue' - the parent birds can do a much better job than we ever can.
