The peregrine falcons nesting on Norwich Cathedral marked the Easter weekend with an egg of their own - as a fourth arrived in the clutch.

Experts believe this will be the last egg of the season as the pair have now started to incubate the eggs full time.

Both birds will take turns sitting on the eggs - allowing the other to hunt for food and stretch their wings.

On Sunday evening the pair were buffeted in winds up to 50 mph (80 km/h) in their nest high on the cathedral spire as Storm Katie blew through the county.
