Responses of captive blackbirds to a new insecticidal seed treatment
Article Abstract:
A study of red-winged blackbirds (Agelaius phoeniceus) and brown-headed cowbirds (Molothrus ater) reveals that a new seed treatment insecticide, imidacloprid, is an effective bird repellent. Rice seeds and wheat seeds applied with the chemical curbs crop damage. However, imidacloprid does not cause any irritation to the birds and is not a sensory repellent. The insecticide comes into effect only after ingestion, and the birds reject it only after constant feeding. The chemical is cost-effective and acts as a bird-deterrent and insecticide.

Seed color avoidance by captive red-winged blackbirds and boat-tailed grackles
Article Abstract:
One way of preventing damage to crops by birds is to use visual stimuli which repel birds. Diurnal bids can see colors well. The way that red-winged blackbirds respond to food colors has not been researched, and this species and boat-tailed grackles are pests that damage crops in the southern US. A study has found that these species least favor blue, so this color could be used as a way of deterring birds from eating crops. More research into color perceptions by birds is needed.

Methyl anthranilate as a rice seed treatment to deter birds
Article Abstract:
The effectiveness of ReJex-iT AG-36, which contains methyl anthranilate (MA), as a repellent against red-winged blackbirds which feed on rice seeds was tested in both aviary and field conditions. During aviary tests, MA-treated rice seeds were able to reduce consumption by 2.5%. During field tests, however, consumption of MA-treated rice seeds was only between 27-34% while consumption of untreated seeds were as much as 73%.
