The possible role of uropygial gland-secreted compounds in olfactory discrimination of sex or sex attractants in the budgerigar, Melopsittacus undulatus, was investigated using behavioral 2-choice tests and gas chromatography-mass spectrometry analysis. Our data showed that female budgerigars were capable of distinguishing males from females in a Y maze via body odor, indicating its sexual dimorphism. When we conducted a chemical assay of the uropygial preen gland secretions, we found 4 times… CONTINUE READING
