Methods of identifying the avian repellent effects of a compound and methods of repelling birds from materials susceptible to consumption by birds

A method for identifying compounds for repelling birds from consuming or utilizing a material otherwise susceptible to consumption or utilization by birds consisting essentially of the following steps:

• a) selecting a compound having an aromatic core structure characterized by one of the following core ring structures ##STR3## wherein R.sub.1 or R.sub.1' or R.sub.1" is an electron donating group and R.sub.2 is an electron withdrawing group or a neutral group which group does not substantially hinder electron donation to the core ring structure by R.sub.1 ;
• and b) testing said compound for repellency by comparing (i) the consumption or utilization by a bird of a material with (ii) the consumption or utilization by a bird of the same material to which an avian repellent compound selected according to step a) has been added, whereby a reduction in consumption of at least about fifty percent as compared to the amount which would be consumed or utilized by said birds in the absence of said compound represents repellency.

A method of repelling birds from consuming or utilizing a material otherwise susceptible to consumption or utilization by birds consisting essentially of the following steps:

• a) selecting at least one compound from the group consisting of alpha-aminoacetophenone, ortho-aminoacetophenone, meta-aminoacetophenone, para-aminoacetophenone, ortho-hydroxyacetophenone, ortho-methoxyacetophenone, meta-methoxyacetophenone, para-methoxyacetophenone, 3-aminobenzoic acid, 4-aminobenzoic acid, 4-ketobenztriazine, coniferyl benzoate, cinnamyl benzoate, 3-4-dimethoxycinnamyl benzoate, coniferyl alcohol, cinnamyl alcohol, 3-4-dimethoxycinnamyl alcohol, acetophenone, 2-amino-4,5-dimethoxyacetophenone, methyl-2-methoxybenzoate, methyl-4-methoxybenzoate, methyl benzoate, anthranil, 2-aminobenzyl alcohol, N,N-dimethyl aniline, ethyl phenyl acetate, methyl phenyl acetate, phenathyl alcohol, benzaldehyde, salicylaldehyde, o-tolualdehyde, o-anisaldehyde, pyrole, pyridine, pyrazine, indol, peperazine, isoquinoline, benzothiole, 5,6,7,8-tetrahydroisoquinoline, 2-acetyl thiazole, 2-acetyl thiophene, thiazole, and tetrahydroquinoline;
• and b) providing an avian repellent amount of said compound to said material.

A method for repelling birds from consuming or utilizing non-potable water consisting essentially of providing at least one anthranilic ester selected from the group consisting of methyl anthranilate and dimethyl anthranilate to said non-potable water in an amount sufficient to reduce consumption of said non-potable water by at least about fifty percent as compared to the amount of said non-potable water which would be consumed or utilized by said birds in the absence of said compound.
