^ Finding a bird in this suburb area is very difficult. There are two reasons for it; First is that there are still many trees here which gives natural habitat to birds. Secondly, there are still many wild birds living in this area. If you notice each morning birds come in this area from south and each evening they go back to south.
I am not trying to be pessimistic but chances of finding that bird is extremely slim. It is much more possible that in evening your bird might have followed other birds and went to south.
It is time for you to pray to Allah for well being of your bird. Within few days of this new freedom, it will learn how to live in wild and how to cooperate with other birds.
Maybe, this freedom is what Allah intended for your bird. In evening go to your roof, face south and stand silent for a minute to say farewell to your bird.
Oh by the way, you may wonder what is in south? South of Adyala has lots of trees and water ponds. I did always wonder why birds go to south in evening until I saw it in Google Earth.
