Excuse me, what kind of bird is this … it has orange and brown feathers in its mouth, and the neighbor picked it up and sent it … it's a young bird, quite big.
This is a young falcon. As for what kind of falcon it is, I feel a bit like a falcon. But your pictures are too few to judge. Can you send more photos? Two photos from different angles, abdomen, front and side.
But anyway, this is a young falcon.
I hope I can help you.
