Early season challenges at the Canning River shorebird camp

While our Spoon-billed Sandpiper crew was starting their surveys out of Kotzebue, our Canning River shorebird crew was preparing to get into the field on the North Slope of Alaska.
Half the challenge of our field season in the Arctic National Wildlife Refuge is just getting to our study site. Located three miles from the Beaufort Sea on the Canning River Delta, the site is accessible only by bush plane on skis or tundra tires, depending on the conditions. After a week of prep in Fairbanks, we headed north on June 5th on a 10-hour drive on the Dalton Highway to a US Fish and Wildlife Service bunkhouse at Galbraith Lake. From there, we would be close enough to shuttle ourselves and our 3500lbs of food and research gear on hour-long flights to our study site.
The drive was stunningly beautiful as we crossed the White Mountains and the Brooks Range before descending down to the lake in the foothills of the mountains. The plan was to fly in our people and gear from Galbraith to the Canning River camp the next day, weather permitting. Unfortunately, the persistent north wind kept a layer of fog over the coastal plain and, though the weather in Galbraith was perfect, we could not fly into camp.

Over the next eight days we repeated the pattern of gearing up, waiting for the weather to clear, and standing down as the flight was called off again. Our consolation was spending over a week in one of the most beautiful spots on the planet. Galbraith Lake is nestled in among the mountains on the North side of the Brooks Range. The tundra is dryer and features easier walking than our field site and we took advantage of our delay to explore the foothills and landscape around the cabin.

Finally, on June 13, we got a brief window of good weather and were able to make a series of flights into camp to bring in some of the crew and supplies. The snow was unusually deep and persistent on the coastal plain this year so, despite the fact that we arrived two weeks later than last year, the snowpack was much more extensive and birds were still arriving.

The flight into camp is always stunning. As the mountains fall away to the South, the entire coastal plain and vast river deltas open up ahead, with the endless ice sheet over the Beaufort Sea visible to the North. Our early season landing strip is on a frozen lake about a half a mile from camp. Unfortunately, with the extensive snow cover, it was hard to tell which lake was the right one, and the first two crews and gear were dropped off on a lake about two miles away.

Even after finding the correct landing site, we still had to haul all of the remaining gear via sled up to the campsite through ice, slush, and tussock tundra. The weather closed back in the following morning, and the full crew was not united in camp for another two days.

The Canning River camp is larger than it has been in past seasons and features several concurrent studies. The team from Manomet is working closely with the US Fish and Wildlife to search for Semipalmated Sandpipers and Dunlin that had been tagged with GPS trackers last year. We are also deploying new tracking tags on Pectoral Sandpipers and American Golden-Plovers.

These trackers, which sit on the birds like backpacks, record precise locations of the birds after the breeding season and should allow us to identify important staging and feeding sites for conservation along the Alaskan coastlines.

In addition to the tracking study, we are working as US Fish and Wildlife Service volunteers and assisting the University of Alaska, Fairbanks with multiple projects on the coastal plain. One of these projects assesses the efficacy of monitoring nests with cameras and temperature loggers in an effort to reduce the number of nest visits needed to monitor nest survival. At the same time, a team is conducting a study of the Arctic Fox population in the area by collecting DNA from hair snares and scat.

We are also catching waterfowl to assess health indicators and prevalence of disease in the population. Finally, we are collecting information on insect diversity and abundance and the presence of herbivores in the study area.
My next post will describe what we found over the following weeks through long days searching for nests and tagged birds. Despite the weather challenges it is an incredible privilege to be able to work in this beautiful and pristine landscape.
