Lead poisoning, especially in hunting areas, poses a significant risk to white-winged dove health. A 2010 Texas study found that 66% of doves had elevated lead levels. The study noted that birds with lethal concentrations of lead were not found because accidental ingestion of lead shot can kill birds in just two days, and that they are incapacitated before that point, meaning that such birds died before they could be collected by researchers.
