peregrine falcon - Tate Modern chimney

A lonely peregrine  up on the Tate Modern chimney this afternoon ....not a great picture but Through the RSPB scope I could clearly see she /he moving his mouth as if angrily screaming , or so it seemed to me . The RSPB man told me they think there are 25 of them in London, he also said he'd seen Honey Buzzards while doing his stint at the Tate Modern. I was thrilled to see this Peregrine - imperious and apparently in a white hot rage above the city.

A peregrine falcon high on the Tate Modern chimney this afternoon, moving his/her mouth as if screaming, an erupting rage of yellow eyes.

A documentary about these birds claimed to measure a peregrine in a hunting stoop (dive) at 242 mph- it's the fastet animal on the planet. The RSPB man said they couldn't tell its gender, like sparrowhawks the female is bigger - this is called sexual dimorphism.
