Peregrine falcons have been nesting on the roof of Merton Civic Centre in Morden each year since 2015.
The webcam is normally working from early March until the end of the nesting season in August.
What to look out for
The female normally lays three or four eggs in late March or April, which hatch about a month later. The chicks fledge at 38-44 days old. The adults then spend two months or more teaching the young to hunt before they become independent.
