title: Comparative efficiency and accuracy of surgical and cytogenetic sexing in psittacines.
abstract: Otoscopic surgical sexing and chromosome analysis through lymphocyte culture were undertaken in 22 psittacine birds of eight species for the purpose of establishing their sex. Comparison of the techniques involved considering success rate, quality of determination, cost, efficiency, and risk. Surgical endoscopy appears to be preferable to chromosome analysis in all categories except risk.
