Project SNOWstorm and Snowy Owl Research
As a result of the historic irruption of snowy owls into the Northeast and Midwest in the winter of 2013-14, Scott Weidensaul and several colleagues formed Project SNOWstorm, which has grown into the largest effort to study the winter ecology of this Arctic raptor in North America.
Project SNOWstorm (the name derives from the four-letter banding code for the species, SNowy OWl), now involves more than 40 researchers, banders, wildlife veterinarians and pathologists, along with dozens of organizations and agencies, across North America. The work has several major and overlapping components:
--The deployment of GPS/GSM transmitters on wintering snowy owls, which provide an unprecedented level of detail into the movements of these raptors. In just three years, SNOWstorm has tagged 43 owls in 10 states from North Dakota to Maine, allowing us to see on an almost minute-to-minute basis -- and in three dimensions (latitude, longitude and altitude) -- where and how these birds are moving, what habitats they're using, and how they're behaving.
The telemetry data are available in interactive maps, updated regularly through the winter season, that allow anyone to experience the excitement of tracking the movements of these huge, white birds. We also regularly update our blog during the winter field season, and as new information emerges.
--The collection of feather, blood and tissue samples, which allow a range of genetic, toxicological and isotopic analysis. Among the early findings are frighteningly high levels of methylmercury, an air pollutant generated by coal-fired power plants, and which is linked to reproductive and behavioral problems in wild animals.
--Necropsies of dozens of snowy owls salvaged across the irruption zone each winter -- birds that were accidentally killed by vehicles, planes, electrocution and other mishaps. While unfortunate, these birds provide the opportunity to examine the overall health of the wintering population, including parasite loads and diseases.
--Photographers have uploaded thousands of geo-tagged images of snowy owls, showing open wings and tails, which allow us to age and sex most individuals and map age- and sex-class distributions.
Funding for Project SNOWstorm has come from the general public, including several very successful crowd-funding campaigns on Indiegogo, as well as generous donations from a variety of ornithological, birding and natural history organizations. Because everyone involved in Project SNOWstorm volunteers their time, every penny we raise goes directly into research.
