The pigeons in Woking are looking nervous. There may be safety in numbers but there's danger in the air.

A pair of peregrine falcons have, for the second year in a row, chosen the top of an office block to nest.

You've got the female known as the falcon. She's sitting just outside the nest box next to one of the external cameras we've got.

The man will do the incubating as well. They share it.

Unlike in the countryside peregrines have no predators in the city and their numbers are on the rise.

They like nesting on sea cliffs and quarries and this isn't too dissimilar you get good updrafts with big office blocks like this.

They like a position which is very high up. they've got exceptionally good eyesight and they can pick up prey things like pigeons in flight from a very long way off and it's a good sort of launchpad for them.

Swooping from that height they can reach speeds of 180mph.

The nest box was fitted last year along with a webcam. It became cult viewing with 5,000 people watching as the parents helped their young hatch.

The young chick calls from within the egg and the adult can hear that. I believe that the adults do help a little bit just to encourage it to come out of the egg.

Incubation usually takes 6 weeks so they should hatch at the end of April. To watch a live webcam of the peregrine falcons, click here.
