A banded snowy owl named Baltimore has just returned from the north to his home base in Maryland for the third year in a row, according to his watchers at the organization Project SNOWstorm, his travels providing researchers with a treasure trove of information.
Baltimore, an adult male, age uncertain, sports a high-tech GPS transmitter that has given the project scientists rare insight into the travels of snowy owls. Since first being GPS-tagged in Feb. 2015, he's logged more than 6,200 miles of flight.
"The information we've gotten from Baltimore is by far the most detailed record of the movements of any snowy owl ever tagged," said David F. Brinker, a co-founder of the project and currently a biologist with Maryland's Department of Natural Resources.
"We have locations - accurate to a meter, and in three dimensions, including altitude - every 30 minutes for almost his entire migration," he added. "That's more than 14,000 GPS points, and counting. No snowy owl has ever been tracked for so long with such precision."
How Owls Spin Heads Around
And, oh, the places Baltimore's been!
According to Project SNOWstorm, he spent early 2015 wintering in Maryland and New Jersey along their coastlines, before heading north through Manhattan, up to Lake Ontario and then farther north still, ultimately reaching the northern tip of Ungava Peninsula, just 300 miles below the Arctic circle. (See the image below to glimpse an outline of his flight path.)
Last fall, Baltimore headed south, once the autumn Arctic chill became too much. By last December, he was on the shores of Lake Ontario, and now he's back in Maryland.
Snowy-Owl Migration To U.S. Among Biggest Ever
Baltimore was first captured by U.S. wildlife biologists on his first migration in 2014, at Martin State Airport just outside Baltimore. He was relocated safely away from airplane flight paths, given a leg I.D. band, and then left alone. But he came back to the airport in Feb. 2015, and on that occasion he was given his fancy GPS tracker. Ever since, Project SNOWstorm has kept an eye on his travels.
