waterfowl ecology and avian influenza in california: do host traits inform us about viral occurrence?we examined whether host traits influenced the occurrence of avian influenza virus (aiv) in anatidae (ducks, geese, swans) at wintering sites in california's central valley. in total, 3487 individuals were sampled at sacramento national wildlife refuge and conaway ranch duck club during the hunting season of 2007-08. of the 19 anatidae species sampled, prevalence was highest in the northern shoveler (5.09%), followed by the ring-necked duck (2.63%), american wigeon (2.57%), bufflehead (2.50%), g ...201020521673
