Snowy owls tracked through U.P. and Midwest

Snowy owls are becoming a more frequently spotted bird in the U.P., and some scientists are finding that handy as they can be captured for tracking to better understand their habits.
 
Excerpt: Once a rare sight, the birds have begun to move into northern states, including Michigan and Wisconsin, and states in the Northeast, according to the Kalamazoo Gazette. They sometimes create a dangerous nuisance on airports, where they like to perch to watch for mice and voles across the open expanse that may resemble the tundra to them, said Rich Keith of the Kalamazoo Valley Bird Observatory. The large birds, with wingspans of up to five-and-a-half feet, can interfere with flights.
