The bravest bird that springs to mind now is the robin, I reckon. The little fella isn't shy and dares to come very close when I'm the garden. Um, once.. I was laying bricks (building a kitchen for a friend) and there a robin was quite interested in what I was doing. The bird just sat a meter away from me and was observing me.
Oh, mustn't forget to mention the turtle dove too. The pair that frequents my garden will try to chase off magpies and/or jackdaws quite often and succeed doing so. Kinda think, they have a sense that I will cover their backs and go brave that way. Dunno..
The blackbird (T. merula) couple here aren't afraid of me one bit either. They often come begging for food when I'm outside and come up to me (up to ½ a meter). She.. often walks around and underneath the chair when I'm sitting outside. Stupid chickens.
