A second egg was laid by a pair of wild peregrine falcons nesting on the side of Norwich Cathedral spire at about 5am today.

The first egg in the new clutch was laid at about 4.30pm on Thursday, almost exactly a year after the first eggs appeared in 2012 on March 22.

A maximum of four eggs are likely to be laid over the next few days, usually with 24 to 36 hours between each. Incubation will take 30 to 33 days before any are expected to hatch.

Four eggs were laid last year with three hatching, and the chicks were the first born in Norwich for 200 years.

The Hawk and Owl Trust, a wild bird of prey conservation charity, installed a nest platform 75 metres above street level in February 2011 to encourage breeding.

Peregrine falcons are usually a bird of the sea cliffs, but have increasingly been moving into UK cities in recent decades.

A male first appeared at Norwich Cathedral a few years ago and was later joined by a female.

They are the only two peregrine falcons in Norwich, protecting a large territory, and remain at the cathedral all year round.

Activity on the ledge is being followed 24 hours a day by two cameras, one of which is broadcast on the internet.
