Greenfinch fledgling November?

Hello,

I have this little fella in the garden, completely not afraid of me. I think it's greenfinch fledgling?? But in November??

He let me move him into bushes he came from with gloves on, as when he failed to reach the fence, he got himself cornered into very busy area with magpies and jackdaws.

Doesn't seem to have eating or wings quite figured out. Came very close to me, not minding me moving about. Seems to come out of hiding when i'm out (big birds stay away then).

When I picked him up to move him I noticed what seems to be a little wound possibly but didn't want to mess with him to check further. With not seeing greenfinch adults here before, I'm a bit baffled where he came from to be fair and why he's so tame with me. 

I first saw him last night 10PM which I've found odd. 

I kind of want to let him be, just wonder why so late in the year and why so timid? Doesn't seem normal to me? 

What do you think?
