Wild baby chick/bird questions?

Different species of birds have different food requirements, a picture would help greatly in identifying it so you know what to feed it until you get it to a wildlife rehabilitator. You must get it to one fast or it will die without proper care. Baby birds need alot of care, if you work then you won't have time for it at all. They need feeding aproximatley ever 30mins daylight hours and every 2hours at night time... fledging is an entire different story as well. Baby birds can't regulate their body temperature well at all so a warm hot water bottle is best, pile bedding over it and around the bird so it's warm. It could be a nectivore,seedivore or a carnivorous species so a picture or a very detailed description would help. Please get it to a rehabilitator though, you mean well.. but baby birds are so fragile.
