No places to call for help and done a bit digging on line. Kept this little wild bird in a box, let it calm down then provided some bird seeds and water. Next morning, found it hurt it’s head probably due to many hitting on the light pole. Some topical antiseptic microbicide solution applied. Little bird could ate and pooped the 2nd day.
Rested all day, 3rd day. On 4th morning, found it walked outside of the box. It shot to the high sky, the second front door was opened for him. Free or die, no matter how warm and food-rich OBS’s place is. Even little wild dove knows, too bad not people in these days.
