Members of the RSPB are on hand to educate the public about these magnificent creatures. We learnt that the falcon only returned to central London about a decade ago, following their local elimination during WWII (the birds were supposedly a threat to carrier pigeons, and shot down). Around 20 falcons now make their home in London, a number thought to be close to saturation for such highly territorial birds. Misty and Bert do not nest on Tate Modern, but use its chimney as a vantage point for hunting.
The observation platform will remain in place until 12 September, and is open from 12-7pm daily.
