Little songbirds cover more than 300 miles a day on their annual migrations, flabbergasting researchers who expected a much slower flight.

For the first time, scientists were able to outfit tiny birds with geolocators and track their travel between North America and the tropics, something only done previously with large birds such as geese.

New tracking equipment, weighing only a little more than a paper clip, is now allowing the tracking of purple martins and wood thrushes, researchers report in Friday's edition of the journal Science.>

But the proliferation of cataloguing and altering so many creatures makes me wonder sometimes...
