The fulmar is part of the family of "Procellariiformes" which includes Albatrosses, Shearwaters and Petrels. Also known as the "Tubenose", as you can see from the above picture which shows the tube on top of the bill, inside this tube they hold a foul-smelling oil which they spit out at intuders who try and get close to their nest.
The pair of Peregrine Falcons were showing very well and calling at each other, then one bird would take to the sky and then return to its postion on the cliff, then the second bird would do the same. May be a bit of displaying from the couple who have been resident in the area for some time now. On my next visit I am going to work hard on getting some decent flight shots.
