Common pest birds in the United States include the non-native European starling (Sturnus vulgaris), house sparrow (Passer domesticus), and the pigeon (Columba livia domestica), as well as native birds including Canada geese (Branta canadensis) and gull species (Laridae). Large concentrations of pest birds can create human health hazards and monetary losses due to consumption of crops, depredation, and fecal contamination and accumulation. Fecal contamination hazards include the potential spread of zoonotic diseases including antimicrobial-resistant zoonoses and human injury due to the accumulation of fecal material on walking surfaces. Additionally, fecal accumulation causes …
Reconciling Sensory Cues And Varied Consequences Of Avian Repellents, Scott J. Werner, Frederick D. Provenza
Reconciling Sensory Cues And Varied Consequences Of Avian Repellents, Scott J. Werner, Frederick D. Provenza

We learned previously that red-winged blackbirds (Agelaius phoeniceus) use affective processes to shift flavor preference, and cognitive associations (colors) to avoid food, subsequent to avoidance conditioning. We conducted three experiments with captive red-winged blackbirds to reconcile varied consequences of treated food with conditioned sensory cues. In Experiment 1, we compared food avoidance conditioned with lithium chloride (LiCl) or naloxone hydrochloride (NHCl) to evaluate cue–consequence specificity. All blackbirds conditioned with LiCl (gastrointestinal toxin) avoided the color (red) and flavor (NaCl) of food experienced during conditioning; birds conditioned with NHCl (opioid antagonist) avoided only the color (not the flavor) of …

An effective, economic, and environmentally safe bird repellent is needed to reduce blackbird (Icterinae) depredations to newly planted rice. We evaluated Flight ControlTM, a 50% anthraquinone product, as a seed treatment for newly planted rice. We treated rice seed with Flight Control at a 2% (g/g) concentration (1% active anthraquinone) the day of planting. This concentration reduced the number of blackbirds (P=0.0003) using treated fields and blackbird damage to rice seed (P=0.0124). The chemical concentration of anthraquinone on rice seed averaged 0.79% (SE=0.06%) at planting; 0.39% (SE= 0.04%) at day I, 0.34% (SE=0.05%) at …
Evaluation Of Chemical Repellents For Reducing Crop Damage By Dickcissels In Venezuela, M. L. Avery, E. A. Tillman, C.C. Lauker
Evaluation Of Chemical Repellents For Reducing Crop Damage By Dickcissels In Venezuela, M. L. Avery, E. A. Tillman, C.C. Lauker

In Venezuela, lethal control of wintering Dickcissels (Spiza americana) is considered a threat to the species survival. To help farmers protect their rice and sorghum crops from depredations by Dickcissels and to minimize the killing of large numbers of these birds, alternative non-lethal crop protection measures are needed. To that end, the responses of captive Dickcissels to three bird-repellent chemicals applied to rice seed were evaluated. In one-cup feeding trials, treatments of methiocarb (0.05% g g-1, applied as Mesurol® 75% wettable powder) and anthraquinone (0.5%, applied as Flight Control® ) reduced consumption of rice by 70% …

1999 Bird Strike Committee-USA/Canada, First Joint Annual Meeting, Vancouver, BC
Birds found at or near airport flight operations pose a threat to aircraft. There were 2843 reported bird strikes in the United States in 1997 and 837 reported bird strikes in Canada for the year 1998. Potential for loss of life and economic losses due to aircraft damage have driven the need for research into effective techniques in lowering the risk of bird strike in the immediate area of flight operations. Flight ControlÔ is a documented bird repellent. Flight ControlÔ was released commercially in January 1999 in the United States for use on turf, ornamental trees and bushes, building surfaces …
Development Of Seed Treatments To Control Blackbirds, Michael L. Avery, David Decker, John S. Humphrey
Development Of Seed Treatments To Control Blackbirds, Michael L. Avery, David Decker, John S. Humphrey
Proceedings of the Eighteenth Vertebrate Pest Conference (1998)
Bird repellents to protect seeds are a potentially important aspect of integrated vertebrate pest management strategies. Yet, there currently are no repellents registered for seed treatment uses. This is due not to lack of effective candidate compounds, but to monetary and regulatory constraints that inhibit commercialization of promising compounds. Two examples of this dilemma are methiocarb and anthraquinone, each of which has considerable potential for bird repellent uses and each of which faces considerable registration hurdles as prospective seed treatment compounds. A concerted, coordinated effort among private industry, producer groups, and state and federal agencies may be the best strategy …
