West Nile virus (WNV) has spread rapidly across North America, resulting in human deaths and in the deaths of untold numbers of birds, mammals, and reptiles. The virus has reached Central America and the Caribbean and may spread to Hawaii and South America. Although tens of thousands of birds have died, and studies of some bird species show local declines, few region-wide declines can be attributed to WNV. Predicting future impacts of WNV on wildlife, and pinpointing what drives epidemics, will require substantial additional research into host susceptibility, reservoir competency, and linkages between climate, mosquitoes, and disease. Such work will …

Many species of birds in Uruguay frequent vineyards and damage grapes, both species that are considered crop pests and species that are protected by law because their conservation and protection are desirable. We surveyed 70 farmers in the Department of Canalones, the main grape growing region in Uruguay, to determine their perceptions about the nature and severity of bud depredations and the methods being employed to reduce such damage. Sixty-seven percent of respondents reported receiving damage from birds. Bird depredations were considered a serious problem by 58% of respondents, a moderate problem by 19% of respondents, and a minor problem …
