My Bird is Lost can anyone help please?

Can it fly? It will most likely not survive because it is a captive bird, i'm sorry. Put up flyers. Put its cage at your backyard or the roof where your bird can see it, so when it wonders hungry around and saw its cage, it will make its way back since thats its source of food. Inform ur neighours to contact u if they see a cockatiel that is why i say put flyers. If it cant fly, no use putting the cage on the roof. Or you can even try spreading its seeds to the places where you think he might be at. Good luck.
