Great Skuas are certainly formidable creatures with not many endearing traits, Roy. In the past I have seen them kill adult Puffin and Kittiwake, but last year I was surprised by the actions of one off Burghead in the Moray Firth. It was hurtling behind an adult Gannet and suddenly seized the Gannet's wing, whereupon both birds crashed into the sea. An untidy flapping scuffle then took place until somehow the skua had hold of the Gannet's neck and was stood on its back. At this point, the skua began violently dunking the Gannet and I was beginning to fear the worst. All at once, the Gannet broke free and pattered for a short distance along the sea's surface, but the skua was straight after it, took hold of its wing again and brought it back into the sea. By this time there were quite a lot of body feathers blowing around and at least two of the Gannet's primaries had been lost. Suddenly, the weakening victim disgorged its stomach contents and the skua released its grip and turned its attention to these. The Gannet again pattered across the surface, then managed to take flight. It flew off in a somewhat dishevelled condition and looked quite the worse for wear. I just hoped that it made a full recovery later.
Regards, Steve.
Nature is amazing isn't it! Gannets often cough up the goods pretty quickly when attacked by a Bonxie, so maybe this individual had never been attacked before, or was suffering from delusions of physical grandeur!
I've seen Greater Black-backed Gulls face down Bonxies (about the only bird that can!), and they can be just as mean. I once saw one toss a Puffin inside out, and another one used to wolf down baby rabbitts whole on a regular basis.
Still, when you consider the cruelty that some people inflict on animals and don't even eat them, the Bonxies and GBBG's look positively angelic.
