Us­ing lit­tle back­packs to track a huge bird mi­gra­tion

Canadian Wildlife - - DISPATCHES -

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.
