Don't worry — the birds aren't taking over London in some Hitchcockian nightmare.
Bird boxes designed to look like London landmarks have been erected in east London in a bid to encourage birds back to the capital.
Replicas of structures including Tower Bridge, Battersea Power Station and the Tower of London have appeared in East Village E20 (previously the Athletes' Village during the 2012 Olympics).
East Village E20 has teamed up with the RSPB to create the boxes, following the recent results of this year's Big Garden Birdwatch, which showed that common garden bird numbers have decreased by around 20% since 2009.
East Village has been chosen, as it's home to many species of birds and wildlife, including rare black redstarts.
The bird boxes are currently situated outside Get Living London’s East Village office, and will remain there for eight weeks before being distributed throughout the Olympic Park.
The bird boxes, created by local carpenter Pete Bagg depict Buckingham Palace, the Tower of London, ArcelorMittal Orbit, BT Tower, Tower Bridge, The Gherkin, Big Ben, Battersea Power Station, Lee Valley Velodrome and One Canada Square (Canary Wharf).
