Captured Birds Fitted with “Geolocators” to Study Migration Flyways

“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.”


GR:  Animal cruelty outside the lab?  Does the geolocator bother the bird at all? Is it irritating or physically limiting?  Were its capture and the geolocator installation traumatic? It seems unlikely that any bird would volunteer to carry a backpack for the rest of its life just so someone could satisfy his curiosity. Oh, you say the researchers are acquiring knowledge that can be used to protect birds?  So why are so many bird species declining? Could it choose, the bird might prefer that the researchers seek to find ways to preserve essential habitat and eliminate the herbicides and insecticides that poison its food.
