The RSPB is outside Tate Modern with a viewing area to watch two peregrine falcons using the 90 metre tall Tate chimney as a day-time roost. These powerful birds are capable of diving on prey at speeds in excess of 180 miles an hour.
RSPB staff and volunteers will be on hand to talk about the peregrines and help focus the telescopes.
Misty and Houdini are mature peregrines who have successfully bred six chicks since arriving in London in 2003.
Anyone with the name Peregrine who can prove their identity and makes themselves known to the RSPB staff or volunteers at the Tate on Monday 24 July will be entered into a draw to win a soft peregrine toy bird that plays an authentic peregrine call.
The peregrines are creatures of habit and the RSPB is hoping Misty and Houdini will put on a good display for this year but they are wild birds and as such, the RSPB cannot guarantee their appearance at the Tate all day, every day.
