Those are fulmars, nesting on the cliff face by The Gloup. It seems that if you get too close to a fulmar or its chicks, it will vomit on you. Yes, vomit. Bright orange oil that absolutely reeks. Even odder, it is the chicks who are the most skilled at projectile vomiting and are so dumb they will upchuck on their own parents for the first few weeks of their lives, until the chicks learn to recognize the adults. (This is why one shouldn’t have children)
An acquaintance told me that when she inadvertently got too near a nest, the birds vomited on her running shoes. No amount of airing, washing, or disinfecting would get rid of the stench; after weeks of trying she had to throw the shoes away. Sort of like the skunks of Scotland.
