Nontarget Bird Exposure to DRC-1339 During Fall in North Dakota and Spring in South Dakota

Metadata Updated: January 29, 2020

Blackbirds frequently use ripening sunflower (Helianthus annuus) as a food source in the northern Great Plains. In 1999 and 2000, the avicide DRC-1339 (3-chloro-4-methylaniline hydrochloride) was used experimentally on fall-ripening sunflower fields in North Dakota so researchers could evaluate its effectiveness for reducing crop depredations by blackbirds. DRC-1339 was applied to rice and broadcast on the ground in a confined area within ripening sunflower fields. One objective of this study was to determine whether nontarget birds, birds other than blackbirds, were eating rice and were exposed to the DRC-1339. In 1999, 8 of 11 (73%) sparrows collected by shotgun in sunflower fields treated with DRC-1339 had rice in their gastrointestinal (GI) tracts. In 2000, 5 mourning doves (Zenaida macroura) and 3 sparrows had measurable DRC-1339 concentrations in their GI tracts, and 3 mourning doves and 1 savannah sparrow (Passerculus sandwichensts) exhibited histopathological signs of kidney damage. In April 2002, 3 or 3 song sparrows (Melospiza melodia) collected by shotgun had rice in their GI tracts. Our results demonstrate that the use of DRC-1339 to control balckbirds in the northern Great Plains will likely expose nontarget birds to the DRC-1339 bait.
