HI Guys I wonder if you can help me, I saved a baby Mouse bird, mother could not be located etc. therefore I have to take care of it. I have had it for about 5 days, I have been feeding it baby purity thus far. It appears to be a fledgling, it has most of its feathers and is able to hang onto things but not yet fly. I urgently need advice on how to properly care for it, such as feeding etc. Attaching a photo here. Help would be very much appreciated.
