(Jan. 7)\u003cbr/\u003eScott Wright/National Wildlife Health Center\u003cbr/\u003eWildlife dieoffs of birds and other animals across the globe is a fairly common occurence. It happens every year in numerous species all around the globe.\u003cbr/\u003eThese samples are then used for additional tests including microscopic examination look ing for bacteria, viruses, parasites, fungal organism and even toxins as  potential causes of death.\u003cbr/\u003eWe'll look for underlying causes. Some of these infectious diseases, some of the toxins affect the central nervous system which in turn affect the bird's coordination and ability to fly.\u003cbr/\u003ePotential human activity forced the birds off their nighttime roost, which is abnormal for these species, causing them to fly in large numbers into surrounding objects which happened to be people's
