Dear gods

Twinkle brought by a large bird home and I don't know how to tackle this 

Edit:-

The situation is under control. I was somehow able to make this little darling come towards the door as it was frantically trying to escape through the walls. 

There's a few dots of blood on the wall and I went to check outside and it had flown. 

If it's injured I'd have to take it to the vet. 

Or at least people will but for now the little bird is nowhere in sight. 

Phew.
