It is really amazing how peregrines have adapted to the big city. For them it is an excellent mountainarea. Full of high cliffs and ridges. The wind in the big city makes all kinds of flight possible like dynamic soaring and gliding. Updrafts generate obstructionlift. Juvi's like to make use of that by letting themselves glide up by updrafts and practise light stoops . Thermals, or updrafts are caused by the uneven heating of air near big buildings or subways.
And last but least there is a lot prey available in the city: pigeons, sparrows, small songbird. It must be like paradise for the peregrines.
