Reward for Lost White Bird in Tampines

White color with a tint of blue on wings and back. We meshed out windows in the living room as we let it free roam. It was hand raised by my mum so it was close to us and not familiar with outside surroundings. We have a flap in the mesh that we can clip or unclip to close the windows. As there is only one clip, we believe it managed to play and escape from there. Please help us, a reward will be given for helping my mum reunite with the bird
