Using little backpacks to track a huge bird migration
A new study has found that tiny Connecticut warblers, which spend breeding season every year in Manitoba’s boreal forests, fly a lot farther than previously thought. Using little “backpacks” — tracking devices that sit between the bird’s wings — Emily Mckinnon of the University of Manitoba found that the warblers make jaw-dropping non-stop flights of 48 hours or more during their migration each year. The birds, which fly over water, end up in South America. They winter somewhere in the Amazon, although the exact location has yet to be confirmed. For more on the warbler, visit borealbirds.org.
