On Saturday I held a ‘cetacean workshop’ in the reserve centre at Cley NWT. It was a good interactive group of interesting people. The morning was classroom based and after lunch we went down to the ‘beach hotel’ to look for a few porpoise out at sea. We unfortunately didn’t see any and guests gradually bid their farewell, but there were a few birds passing to keep interest high. As the light was failing the Black Guillemot that had been moving up and down the coast for the past week or so sailed-by. All the remaining guests managed to get onto it and have a good look through the scope. Some compensation at least for the absence of porpoise.
I took a few record shots as the bird bobbed and dived in the swell. I wasn’t expecting anything spectacular given the distance and the failing light. I put the camera away and took the opportunity to look at the bird through the scope myself. It was then I saw it tilt its head sideways and look up. I’ve seen many birds do this over the years and it’s always indicative of them seeing a raptor above. However, I’ve never seen any species of auk do it previously … and I’ve seen a lot of auks.
Following the guillemots line of sight I looked up myself and very high above us was a Short eared Owl coming in off the sea. Seeing an owl come in-off is always good; a treat in itself. The owl spilled air from it’s wings and steeply dropped down onto the marsh behind us.
I pondered on the fact that the two species, Black Guillemot and Short eared Owl, would rarely be in the same environment and have a chance to interact. So how did the auk know the Short eared Owl was a threat? I guess it is just hard-wired into most birds that birds of prey, whatever the species, are just not good news.
