Effective And Sustainable Prevention Of Avian Damage To Planted Seeds Through Seed Treatment, Jeb A. Barzen, Kenneth E. Ballinger Jr.
Proceedings of the North American Crane Workshop
Several species of cranes and other wildlife have recovered from low populations because, in part, they have adapted to resources found in agricultural environments. If future conservation strategies are to succeed in areas dominated by agricultural use, we must develop sustainable models that solve crop damage problems that are caused by expanding wildlife populations. Using crane damage to planted seed as an example, we propose 1 such model of sustainable crop damage prevention. The deterrent, 9,10-anthraquinone (AQ), is a natural product produced by plants, in part to control bird frugivory, and induces gastro-intestinal distress (temporarily sickens an individual) in sandhill …
Sandhill Crane Foraging Behavior And Damage Estimates In Cornfields During Spring, Jeb A. Barzen, Andrew P. Gossens, Anne E. Lacy
Sandhill Crane Foraging Behavior And Damage Estimates In Cornfields During Spring, Jeb A. Barzen, Andrew P. Gossens, Anne E. Lacy
Proceedings of the North American Crane Workshop
Damage to corn in the spring caused by greater sandhill cranes (Grus canadensis tabida) has increased concurrent with growth of the Eastern Population of cranes. Our study was designed to: 1) describe foraging rates and food acquisition behavior where damage was likely and 2) estimate damage in cornfields treated and untreated with a taste deterrent: 9,10-anthraquinone (AQ; Avipel®). Our 6,251.6-ha study area was located near Briggsville, Wisconsin, and we sampled 415 ± 13.2 individuals/ survey (x ± SE), of which 36 ± 1.7% used cornfields. During 10-30 May 2009, 121 observation bouts of 33 marked cranes that foraged …
