Bird ID please

My daughter works in a local DIY store and she recently spotted 3 Bamboo plants in the skip along with all the other rubbish that gets chucked in there.
Knowing that I would likely take any free plant regardless of how dead they look and try to revitalise them she got permission to delve into that skip and pull those bamboos out. I have to admit all 3 of them do look dead and definitely wouldn't sell to the public but I'm one for giving things a go because you never know just how much life they have left in them.
The Bamboo are Golden Bamboo and are about 10ft tall and very well established, each pot would sell at £40 each (they still had labels on) so the main problem was going to be getting them home as we'd only arrived in a car. We squished them in though and to passing motorists we must have looked a weird sight, my daughter and I were completely hidden by dead foliage.
Once we got them home it was late so I stuck each rootball in a bucket, filled it with water and left them to soak overnight - I actually hope think that the reason the plants looked so dead was because a) they'd been exposed to harsh winds and b) they hadn't been watered in a while, but the culms all looked well green and were still very sappy.
The next day I potted each one up into bigger buckets in homemade compost (garden top soil, compost, manure and grit) and mixed in a handful of Blood, fish and bonemeal to each one, watered them in well and cut a couple of feet from the tops because they're too big for the polytunnel otherwise.

If the culms weren't so green and sappy I may have thought it a hopeless case but there's even tiny little buds coming through the culms so I'm keeping fingers crossed. If they show signs of revival they'll get potted up again next year into huge tubs - they just will not survive the winter here outside.

I managed to snap a piccie of this little bird today and would love to know what it is (I'm thinking some kind of Bunting?) so if any of you know please comment below.

Although I've been busy out in the garden today there hasn't been any significant change so I thought I'd pop in some photos here to bring some brightness to the page (plus we all need to see what we can look forward to when summer finally arrives)
