New study shows that migration flyways and winter destinations of sparrows are unique to each bird

New study shows that migration flyways and winter destinations of sparrows are unique to each bird | Garry Rogers | Scoop.it

"A new paper by Dr. Jeremy Ross from the University of Oklahoma describes the use of tiny devices strapped to birds' backs called geolocators, which capture the individual migration routes of  lark sparrows in North America. By sensing the light levels, these backpacks can pinpoint the location of a bird anywhere in the world, even if retrieving the data-logger can sometimes pose a major problem."

Garry Rogers's insight:

Animal cruelty outside the lab?  Does the geolocator bother the bird at all? Is it irritating or physically limiting?  Was its installation traumatic? It seems unlikely that any lark sparrow would volunteer to carry a backpack for the rest of its life just so someone could satisfy their curiosity. Could it choose, the sparrow might prefer that the researchers seek to find ways to preserve essential habitat and eliminate the herbicides and insecticides that poison the sparrow's food.

Canada Silences Scientists, Targets Environmentalists in Tar Sands Push

Canada Silences Scientists, Targets Environmentalists in Tar Sands Push | Garry Rogers | Scoop.it

Five years ago this month, the firm TransCanada submitted a permit request to build the Keystone XL oil pipeline, which would bring tar sands oil from Canada to refineries on the Gulf Coast. The project has sparked one of the nation’s most contentious environmental battles in decades. The Obama administration initially appeared ready to approve Keystone XL, but an unprecedented wave of activism from environmentalists and residents of the states along its path has forced several delays. Among those pressuring Obama for Keystone XL’s approval is the Canadian government, which recently offered a greater pledge of reduced carbon emissions if the pipeline is built.
