The third of four eggs laid by Norwich Cathedral's peregrine falcons has hatched, keeping mum and dad busy.
The chicks begin "pipping" - rolling around inside the egg to get in the right position - before using an egg tooth on their beak to break a hole in the egg, showing it's ready to hatch.
Once the egg starts breaking, the adults help break the shell and pull it apart.
The fourth chick is expected to appear imminently.
