There is an increasing demand in New Zealand for nonlethal bird repellents to protect food crops and prevent poisonous mammal baits being eaten by native birds. Three food flavorings, dimethyl anthranilate (DMA), methyl anthranilate (MA), and a peppermint extract (Optamint), were applied to wheat as surface coatings at different concentrations and then offered to individually caged house sparrows (Passer domesticus).
