Submission + - Video of wild crow tool use caught with tail cams
willatnewscientist writes: "Scientists from the University of Oxford have recorded New Caledonian crows using tools in the wild for first time after attaching tiny cameras to their tail feathers. The wireless cameras weigh just 14 grammes and can be worn by the crows without disturbing their natural behavior. The trick has provided the first direct evidence of the birds' using tools in the wild and may represent an important development in animal behavior studies."
