We have already described the work we are doing with the GPS-tagged birds, but this year at the Canning River camp we have several additional, but related projects going on. In addition to deploying GPS tags on shorebirds, we are also color-banding for long-term survival and movement studies and taking blood and swab samples for USGS biologists to track the occurrence of avian influenza. Chris Latty, wildlife biologist-ornithologist for the Arctic National Wildlife Refuge and Will Wiese, a graduate student at the University of Alaska Fairbanks (UAF), are running a study using nest cameras to examine waterfowl nesting behavior, predator type and effects, and looking at any effect of the cameras themselves on nest survival rates. We are also deploying these cameras at half of the shorebird nests which helps us determine what the nest predators are and if this is a good technique to use in the future. Spoiler alert! Arctic foxes eat shorebird eggs. What is a bit more unusual are the red foxes in the study area. Red foxes are a rare sight on the Arctic coastal plain and have only recently been sighted this far North. This change is likely related to our changing climate and spells trouble for Arctic Foxes, which are often killed or driven out by their larger cousins. In another unusual occurrence, we may have had one shorebird nest that was destroyed by greater white-fronted geese.

In an attempt to understand how many arctic foxes are using the study area and how many of those are preying on shorebird nests, the USFWS launched a pilot study to try to capture and mark arctic foxes in the study area. Unfortunately, the foxes were already eating too well and none of them felt the need to take the bait and go into the live traps so we could mark them. We will have to get craftier next year if we want to catch the little guys.

With all of the projects going on the camp has been very busy and crowded at times. We started off with 7 people in camp. From Manomet, Shiloh Schulte, Metta McGarvey, Alan Kneidel, and Alex Lamoreaux. From UAF, Will Wiese, Jessica Herzog, and Elyssa Watford. The UAF crew was in camp from May 31 to June 20 and was focused primarily on waterfowl. Despite the consistently terrible weather during this period, they managed to get out in the field and cover an impressive amount of ground to find goose nests and trap waterfowl for banding and sampling. Despite the long days, they all managed to infuse a huge amount of energy and fun into camp. Will in particular never seems to run out of energy and was generally game for anything from dishwashing, to games, to an epic hike, no matter how long he had spent in the field that day. Jessica is an undergraduate student at UAF and this was one of her first field jobs. Somehow she managed to keep up with Will in the field (no easy task) and remain constantly enthused about the work. Elyssa is starting her master’s work at UAF and will be working primarily with Common Eider on the barrier islands in the Refuge.

On the 15th of June we were joined in camp by Patricia Del Vecchio and Steve Berendzen, the acting refuge manager, bringing in the total in camp to nine. Patricia and Steve were setting up the fox tagging project and were out in the field for long hours deploying and checking traps. Both Patty and Steve have a wealth of knowledge and experience from working in Alaska for many years and dinner conversation was always fascinating. For instance, I did not know that Golden Eagles would hunt Caribou calves! Steve was only able to be in camp for a few days and had to leave on the 20th with the UAF crew. Chris Latty and Patches Flores joined us on the 20th to carry on the waterfowl work. Chris could only stay a few days as well, but Patches remained with Alan and Alex to close out the season.
Our ride home arrives in camp on June 30th.
Metta and I left on June 30th, heading for Fairbanks and back to the “real” world. Lifting off from camp is always a humbling experience. The scope of the study area, which feels huge when you are trudging through it for miles every day, suddenly looks tiny against the sweeping panorama of the landscape from 5000 feet.

After all the coming and going in camp throughout June, the remaining crew is down to Alan, Alex, and Patches for the month of July. I imagine camp will feel empty but peaceful for the remaining weeks. We wish them well and good luck with the mosquitos!
