In Louisiana and Texas DRC-l339 treated brown rice is used to manage blackbird populations that cause severe damage to newly planted rice. Non-target bird species have been observed on some DRC-1339 bait sites. We conducted dietary toxicity tests to provide additional data on the toxicity of DRC-l339 to the following non-target species observed on DRC-1339 bait sites: savannah sparrows (Passerculus sandwichensis), Canada geese (Branta canadensis), snow geese (Chen caerulescens), mourning doves (Zenarda macroura), western meadowlarks (Sturnella neglecta), and American tree sparrows (Spizella arborea). During our 5-day DRC-1339 dietary …

Nontarget bird use of DRC-1339 bait sites was assessed during operational baiting programs from 2000-2002 in Louisiana and from 2001-2002 in Texas. DRC-1339 is an avicide registered with the U.S. Environmental Protection Agency to manage blackbirds causing damage to agriculture. It was used in Louisiana between 15 February to 15 March and in Texas from January though March to protect newly planted rice. In Louisiana, there were 55 bait sites observed during 316 observation periods (158 observation hours) and 312 flush-counts conducted from 2000-2002. In Texas, there were 26 bait sites observed during 182 observation periods (91 observation hours) and …

Red-winged blackbirds (Agelaius phoeniceus), common grackles (Quiscalus quiscula), and brown-headed cowbirds (Molothrus ater) cause extensive damage to newly planted and ripening rice. The blackbird-rice problem has generated considerable public pressure in states such as Louisiana, Texas, California, Arkansas and Missouri, to find more effective methods of reducing damage caused by blackbirds. USDA/APHIS/WS National Wildlife Research Center (NWRC) works closely with various state rice growers associations and the USDA Wildlife Services (WS) state operational programs to address this high-priority issue. NWRC conducts a multi-faceted research program aimed at resolving blackbird-rice problems. Research focuses on determining …
