Baby Sunbird

I was on a phone call outside my friend's office when I heard peep, peep, peep, coming from somewhere around me. Obviously, it sounded like there is a nest somewhere, but I was along a corridor overlooking matured trees, which meant that the nest could be anywhere on the tree.
Then, I saw what looked like a mata puteh, fluttering on the ground, trying to pick up what looked like a crumpled piece of paper.
Usually I would just leave things be, but the bird looked distressed that this lump isn't moving much - so I walked to where it was to take a look. This is what I found - a baby sunbird, probably got stuck and didn't have the energy to fly over the parapet wall. She could manage just about a foot off the ground and she was wilting away.
So I picked her up, and brought her to the vet.
He confirmed she's a sunbird, could have had a nest domination problem or perhaps learning how to fly and got stuck along the corridor grounds with no way out. Because she's nectar feeding, it's a problem - she's apparently too big to actually beg for food, but he managed to feed her with some glucose water - it's the first time, I watched a nectar feeding bird feed. It's amazing - she has this pin like tongue!
The great thing is, she's still alive this morning. Ate a good meal last night and slept all the way through. She knows how to step onto my finger and flap her wings.
She's so tiny, she's like a toy.
I'm going to nurse her, until she's able to fly and find her own food. I don't think people keep sunbirds - but let's just hope she recovers.
