Wild baby pigeon - HELP!

[overmarco]

I have found a baby pigeon at my work place in London City. Looked arround, just tall buldings, waited for about 6 hours, no adult bird came to feed him. RSPCA advised me just to leave him there, as they will not help. Checked their website they advise everyone not to interfere on anything. Probably better.

He is full feathered, doesnt look ill; he didnt eat anything the first day, so I had to forced-feed him with a syringe. He is absolutely terrifed by humans and I realised later if isolated he will eat seeds. Not much, but he will eat. The problem is I dont think he drinks water. As he wont eat in the presence of humans, I have no clue if he drinks or not. My bet he doesnt. I give him every day arround 5 ml of water with a syringe. Im afraid to give him more as he literally fights it if I try. I am quite happy he hates people as he it might be his chance of surviving when released. He poops a lot, thats a good sign also.

Questions:
- Is there a trick to notice if he drinks or not
- How much water should I give him per day (I attached a picture)
- How do I teach him to drink. I tried to put his beak in the water, only result is he snnezes a lot. It's hard to make him do something as he is terrified by people. I know a guy who has has racing pigeons, if I place this baby next to them, to see other pigeons feed and drink, will that help? This pigeons is a wild one, not a race that people breed.
