Abstract:

Wintering Lesser Snow Geese (Chen caerulescens) were analyzed for lead and mercury residues and lead shot ingestion. Lead shot ingestion paralleled assimilation of lead residues. Snow geese collected in rice-growing areas had significantly (P < 0.01) more lead residues than marsh area geese. This was attributed to different soil finnness, feeding habits, and hunting practices in the 2 areas. Recent deposits of lead apparently played a major role in lead shot ingestion because lead residues and shot ingestion were greatest during the hunting season. Mercury residues significantly (P < 0.05) declined over the wintering season.
