Update on eider research

30 10 2014

It’s fall, and on Cape Cod, that often means piles of dead eiders rather than piles of rustling leaves. In the multi-year investigation into why so many common eiders turn up dead around Wellfleet most years, the USDA, USFWS and numerous other groups have partnered up and pooled their skill and resources to try to get to the bottom of what’s happening. Right now, the researchers are wrapping up the live bird sampling phase of this fall’s work; they have been trapping birds as they arrive from their breeding islands–some from as nearby as Boston Harbor, some from nearer the Arctic. The idea is to sample their blood and feces to see if they arrive in Cape Cod Bay already having been exposed to, and possibly even shedding the virus. The birds are also banded so that if they ultimately die (of any cause) and are found, we will know what their viral status was as of the beginning of the overwintering season. The Cape Cod Times has posted an article with some rather delightful photos of this work.

Cape Cod is a SEANET hotspot, luckily for us, and many of our dedicated volunteers have offered to help in any way they can. Up to now, biologists were interested in hearing where and when eiders were arriving from the north. With the sampling work completed, the focus will now shift to documenting and collecting dead birds. Anyone, Seanetter or not, can help with this effort, so if you see more than a few sick or dead eiders (and this is not just for Cape Cod), please contact Randall Mickley (randall.m.mickley”at”aphis.usda.gov or 413-658-7113).

The other critical thing to report is any banded bird found dead. Here is a timely time to reissue our dead bird flyer! Please encourage all your friends and neighbors to jot down any band numbers they find and report them. I can’t emphasize enough how valuable those data are!
