Title: An ecological risk assessment of lead shot exposure in upland game birds and raptors

Abstract

There is concern about exposure of birds in terrestrial ecosystems to spent lead shot. Upland birds, particularly mourning doves, ingest spent lead shot; raptors ingest lead shot by consuming wounded game. Mortality, neurological dysfunction, immune suppression and reproductive impairment are effects of exposure to lead. The authors conducted an ecological risk assessment (using the new USEPA Ecological Risk Assessment Paradigm) on the impact of lead shot exposure in upland birds. Large amounts of lead shot are released into the environment each year from shooting and hunting. Doves collected from fields cultivated to attract mourning doves for hunting contain ingested spent lead shot. This might underestimate risk because doves ingesting shot may experience lead toxicosis and not be collected by hunters. Because lead can cause both acute and chronic toxicity if ingested and there is evidence of widespread liberation of lead shot in terrestrial ecosystems, concern for impacts on upland game birds and raptors is warranted. Although this ecological risk assessment does not clearly define a significant risk of upland game birds to lead shot, there is little evidence to rebut the presumption of risk. This issue merits continued scrutiny to protect upland game bird and raptor resources.
