Photographer and guide Paul Goldstein has spent 30 years showing people the Rift Valley in Kenya from ground level.
He has now decided to view it from the air.
These stunning scenes show flamingos soaring across Alkaline Rich Soda Lakes.
Paul says: "I have been mesmerised by the vast shimmering flocks of these birds...".
"...on this day there were plenty on show and the bird's eye view down a long lens was utterly captivating.
