Drumadoon itself is a basalt sill with obvious columnar jointing also seen in this region at Fingals cave and over the water at the Giants Causeway in Northern Ireland. The cliff is eroding to form a series of overhangs and ivy covered ledges that provide shelter for nesting fulmars and other birds. It is quite interesting from a geological perspective, and on the day I was there the place was also hooching with geology students....
The fulmars that nest on the cliffs choose sheltered ledges where they lay an egg either on bare rock or in a shallow depression lined with plant material. They look superficially like gulls, but closer inspection reveals that they have a tube on the top of their bill, like an albatross. They are in fact closely related to albatrosses, and are members of the petrel family. They are well adapted to a life of foraging on the open ocean, with stiff wings for soaring, and the tube
There will be opportunities to watch fulmars and find out more about these charismatic birds during the wildlife festival. Holy Isle Sea Life Special rib trips will be leaving Brodick on the 13th and 14th May, and on the 14th May there will be a survey techniques masterclass along the shore at Blackwaterfoot.
