Is this a Baby Robin??

Hi

I just wondered if anyone could help me please. My two resident Robins have not been in my garden for about 3 weeks (well my male has visited now and again for food but the female hasn't at all). Anyway today I had this little fellow it was in my garden around 6.30pm and it was here for a long time checking out every area of my garden and feeding from my ground feeder.

Could this be a fledgling of my resident Robins do you think? I think it looks young and was looking at it's feathers, they look fluffy. Please tell me I am right, I so want to be a Robin Nana haha

Thanks in Advance
