A vampire bat is caught in a net in Aracy, in the northeast Amazon state of Para, Brazil, on Thursday, Dec. 1, 2005. The bat is being studied for research by assistants at the Goeldi Museum Research Institute of Belem. Continued deforestation of the Amazon region has sent thousands of displaced vampire bats carrying rabies sweeping across northern Brazil, where the flying mammals have bitten over a thousand people, and left 23 dead over the past two months, authorities said.
