Based on the award-winning research of a fourth-year biology student, it should be a safe bet that most migratory birds will be a little late this spring getting back to the area from down south.
After analyzing 18 years of bird banding data, Rachel Hasson discovered that nine varieties of song birds, ranging from orioles to warblers, were arriving back to southern Ontario anywhere from three to eight days early, depending on the change in temperature in any given year.
