Eagle-eyed passers-by might have noticed a familiar figure in the grounds of Ealing Hospital earlier this year.
Strictly Come Dancing winner Hamza Yassin had to use all his moves to capture the even swifter moving peregrines that have made the hospital their home.
Hamza, a wildlife cameraman, was filming the birds for a BBC TV show due to be broadcast at the end of September called Hamza: Strictly Birds of Prey.
The show follows Hamza around the UK capturing his ‘top ten’ birds on film.
Hamza said: “All my life I have had a passion for birds of prey, so this documentary film is a dream come true for me.
“It’s an opportunity to share more of the joy I experienced on Wild Isles while I film my top ten of Britain’s birds of prey.”
Hamza: Strictly Birds of Prey will be broadcast at 7pm on Sunday 24 September on BBC1.
