from the picture you posted, it looks like a full grown adult.
even if the bird is completely healthy, full of life, and uninjured, and can fly perfectly, you should still not attempt to care for it at home. please contact a local wildlife refuge so that they can guide you as to what to do, where to take the bird for release back into the wild, how to release it, etc. things have to be done just right to ensure the birds survival in the wild. chances are, they will take it back to the park where you found it, and release it there. that would be the best thing for the bird, because its family lives there. passerine birds live in families - its mate is probably searching for it everywhere in that park, and its local kin are probably wondering where it is. when you speak to the wildlife professional, make sure you tell them EXACTLY where you found the bird. it will make a world of difference for the birds recovery.
the longer you keep the bird in your house, the less chances for its successful rehabilitiation back into its habitat. so please do a google search and locate a wildlife professional, or an avian vet who can offer guidance as to how to find a wildlife professional.
the chances of the bird perishing under your care are very high, as small passerines like this bird have highly specialized insect diets and high caloric needs that you will not be able to provide in a safe fashion (they have tiny crops) and high metabolism.
so time is of the essence, to treat any injury he might have (there might be one that is imperceptible to you) and to release him back into the wild. an avian vet's and/or a wildlife professional's guidance is critical to ensure the birds survival and successful release.
good luck and all the best to you and the little bird
