Watching Northern Gannets is fun, except when it's not



The high point of my visit to my birth place in Germany in 2009 was a trip from Hamburg down the Elbe River to the diminutive island of Helioland in the North Sea, 29 miles off the coast. The side facing the sea is a 200 feet high rock cliff, home to thousands of sea birds, mostly Northern Gannets, Common Murres and Black-legged Kittiwakes. It was a gorgeous day, bright sun, blue skies. I had only a few hours to photograph the birds, no way of avoiding the mid-day sun with its harsh lights and shadows. But losing myself  in the moment, I was happy and kept firing away at the awe-inspiring assembly of nesting Northern Gannets.

Closely examining the photos after I got home, I discovered the tragic consequences of the Gannets' method of nest construction. The rocks were covered with tons of man-made indestructible trash: plastic lines and pieces of nets that the Gannets had dragged up for nest material in place of their customary sticks and seaweeds, and that ended up trapping many of them, leading to their slow and agonizing deaths.

These juveniles didn't make it
Fortunately this  appears to be the only known Northern Gannet colony in the North Atlantic suffering such  calamity. The North Sea is a shallow shelf sea ideal for shrimping with drag nets over its bottom. Nets are lost or torn apart and remain floating in the water or washed up on the beach. Gannets are known to resort to beachcombing for their nest material. Or perhaps they grab it when the nets are  pulled in for mending.

Until then I had been content archiving my photos on my website; but now I had to write about it, hoping to bring this debacle to the public's attention. That's how I started my blog.

  1. Great post Hilke, how horrible these poor birds. I wonder if people can clean up the site. The dead being there must expose them to infection as well.

    2. Thanks Dan. Back then I had written an email to the bird observatory on the island. Here is their reply:
      "entangling of adult and juvenile Gannets (as well as of other seabirds, mainly Guillemots) in the nest material consisting of remains of fishing gear is a problem known for long time. As far as I know there was no attempt to locate the source of pollution, but for me it appears to be obvious that the pieces of net brought to the Helgoland colony by Gannets originate from North Sea fisheries. As the red sandstone cliff is too soft for climbing, rescue of entangled seabirds is unfortunately not possible."

  3. Beautiful images, Hilke, but so sad to see the consequences of their use of artificial nesting material.

  4. Terrific environmental images Hilke, these have such an emotional impact on me. Something must be done about the way we humans are pollutions our oceans.

    1. Thanks, Mia. "Tragedy of the commons" - nothing will be done because no one is responsible for the ocean. The novel "The Swarm" deals with how the ocean takes revenge on us - it makes you feel good while reading it, but it's just a fantasy.

  8. Great photos of the Gannets - they are beautiful birds - but it is very disturbing to see how human trash becomes an environmental disaster with no-one able to fix it.

  13. The Northern Gannets are especially beautiful birds. I was so very touched when viewing your photographs of the tender interactions between the birds and then saddened to read about the senseless killing. Such a shame ...

  17. Nice images and important story. I had a similar one a few months ago (http://theheronfiles.blogspot.com/2012/06/great-blue-heron.html). I thought I had captured several nice images of a Great Blue Heron catching a fish only to find out when I looked at the photos that the bird had a large fishing lure and not a live fish. Luckily, I don't think it was injured; just spent a lot of energy for no reward.

  20. Hi there - this is a great post. We can all post images that we hope people will like. but now and them people post posts that are a call to arms - just like this one. I hope that something can be done - but I know how persistent these synthetic materials can be.

  21. Trash in the world's oceans is such an intractable problem as long as there are no penalties for flushing waste down into the ocean, no one to police the shipping and fishing industry. Lost nets, "ghost nets", go on fishing forever until torn up or washed on to the shore, albatross young die of starvation being fed plastic waste by their parents... What can we do? It's minuscule: If you happen to see plastic trash on the beach pick it up... don't buy drinks in plastic bottles, don't use plastic supermarket bags...
