The bird could carry some diseases and there is a possiblitity that there are on the bottle top and so i you drink out it you may get the bacteria/disease in your body. However I would just drink.
Probably. It will depend both on the plastic the bottle is made from and its intended purpose.
Reusing a glass bottle is not safe in the least bit. This is unless the bottle has been completely sterilized.
Not if you want to maintain your eyesight.
Not a good idea if it has been stored in leaded crystal (fancy looking), but if is in a glass bottle (like the original container) then it is probably fine.
It is very unwise ever to consider any container which has contained a toxic substance for use as a container for food or drink, no matter how thoroughly you think it's been cleaned. It would be especially foolish to allow a child to drink from a bottle which normally contained a toxic liquid; a child could easily not distinguish in future whether such a bottle contained a safe drink or poison. For the same reason, one should never store toxic substances in containers normally associated with food or drink. Tragedies have occurred when children and adults have drunk from soft drink bottles and other food containers which have been used to hold poisonous substances.
