Abstract

Maturing sunflower (Helianthus annuus L.) is susceptible to damage by birds, especially blackbirds (Agelaius phoeniceus and Quiscalus quiscula). The National Sunflower Association (NSA) identified Blackbird damage as a major issue in the production of sunflower throughout the US. In 2007 bird damage was identified as the number one yield limiting factor in 9% of surveyed fields in North Dakota (Graph 1).
